What is SELECTIVE LEACHING? What does SELECTIVE LEACHING mean? SELECTIVE LEACHING meaning - SELECTIVE LEACHING definition - SELECTIVE LEACHING explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Selective leaching, also called dealloying, demetalification, parting and selective corrosion, is a corrosion type in some solid solution alloys, when in suitable conditions a component of the alloys is preferentially leached from the material. The less noble metal is removed from the alloy by a microscopic-scale galvanic corrosion mechanism. The most susceptible alloys are the ones containing metals with high distance between each other in the galvanic series, e.g. copper and zinc in brass. The elements most typically undergoing selective removal are zinc, aluminium, iron, cobalt, chromium, and others. The most common example is selective leaching of zinc from brass alloys containing more than 15% zinc (dezincification) in the presence of oxygen and moisture, e.g. from brass taps in chlorine-containing water. It is believed that both copper and zinc gradually dissolve out simultaneously, and copper precipitates back from the solution. The material remaining is a copper-rich sponge with poor mechanical properties, and a color changed from yellow to red. Dezincification can be caused by water containing sulfur, carbon dioxide, and oxygen. Stagnant or low velocity waters tend to promote dezincification. To combat this, arsenic or tin can be added to brass, or gunmetal can be used instead. Dezincification resistant brass (DZR), also known as Brass C352 is an alloy used to make pipe fittings for use with potable water. Plumbing fittings that are resistant to dezincification are appropriately marked, with the letters "CR" (Corrosion Resistant) or DZR (dezincification resistant) in the UK, and the letters "DR" (dezincification resistant) in Australia. Graphitic corrosion is selective leaching of iron from grey cast iron, where iron gets removed and graphite grains remain intact. Affected surfaces develop a layer of graphite, rust, and metallurgical impurities that may inhibit further leaching. The effect can be substantially reduced by alloying the cast iron with nickel. Dealuminification is a corresponding process for aluminum alloys. Similar effects for different metals are decarburization (removal of carbon from the surface of alloy), decobaltification, denickelification, etc. Countermeasures involve using alloys not susceptible to grain boundary depletion, using a suitable heat treatment, altering the environment (e.g. lowering oxygen content), and/or use cathodic protection. Selective leaching can be used to produce powdered materials with extremely high surface area, such as Raney nickel. Selective leaching can be the pre-final stage of depletion gilding.

What is BACTERIAL OXIDATION? What does BACTERIAL OXIDATION mean? BACTERIAL OXIDATION meaning - BACTERIAL OXIDATION definition - BACTERIAL OXIDATION explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Bacteria biooxidation is an oxidation process caused by microbes where the valuable metal remains (but becomes enriched) in the solid phase.In this process, the metal remains in the solid phase and the liquid can be discarded. Bacterial oxidation is a biohydrometallurgical process developed for pre-cyanidation treatment of refractory gold ores or concentrates. The bacterial culture is a mixed culture of Acidithiobacillus ferrooxidans, Acidithiobacillus thiooxidans and Leptospirillum ferrooxidans. The bacterial oxidation process comprises contacting refractory sulfide ROM ore or concentrate with a strain of the bacterial culture for a suitable treatment period under an optimum operating environment. The bacteria oxidise the sulfide minerals, thus liberating the occluded gold for subsequent recovery via cyanidation. The BIOX® process is a proprietary technology owned by Biomin South Africa and used under licence by a number of operating mines. The BIOX® process involves bacterial oxidation in agitated tanks for pre-treatment of refractory ores and concentrates ahead of conventional cyanide leach for gold recovery. Under controlled continuous plant conditions, the number of bacterial cells and their activity is optimised to attain the highest rate of sulfide oxidation. The bacteria require a very acidic environment (pH 1.0 to 4.0), a temperature of between 30 and 45 °C, and a steady supply of oxygen and carbon dioxide for optimum growth and activity. The unusual operating conditions for the bacteria are not favourable for the growth of most other microbes, thus eliminating the need for sterility during the bacterial oxidation process. Because organic substances are toxic to the bacteria, they are non-pathogenic and incapable of causing disease. The bacteria employed in the process do not, therefore, pose a health risk to humans or any animals. The bacterial oxidation of iron sulfide minerals produces iron(III) sulfate and sulfuric acid, and in the case of arsenopyrite, arsenic acid is also produced. The arsenic is removed from the liquor by coprecipitation with the iron and sulfate in a two-stage neutralisation process. This produces a solid neutralisation precipitate containing largely calcium sulfate, basic iron(III) arsenate and iron(III) hydroxide. The iron(III) arsenate is sufficiently insoluble and stable to allow the neutralisation product to be safely disposed of on a slimes dam. The neutralisation liquor, purified to contain an acceptable level of arsenic, can be re-used in the milling, flotation or bacterial oxidation circuits.

Phytoremediation
 
19:10
Phytoremediation, meaning "plant", and Latin remedium, meaning "restoring balance") describes the treatment of environmental problems through the use of plants that mitigate the environmental problem without the need to excavate the contaminant material and dispose of it elsewhere. Phytoremediation is a cost-effective plant-based approach to remediation that takes advantage of the ability of plants to concentrate elements and compounds from the environment and to metabolize various molecules in their tissues. Toxic heavy metals and organic pollutants are the major targets for phytoremediation. Knowledge of the physiological and molecular mechanisms of phytoremediation began to emerge in recent years together with biological and engineering strategies designed to optimize and improve phytoremediation. In addition, several field trials confirmed the feasibility of using plants for environmental cleanup. This video is targeted to blind users.

What is RHIZOFILTRATION? What does RHIZOFILTRATION mean? RHIZOFILTRATION meaning - RHIZOFILTRATION definition - RHIZOFILTRATION explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Rhizofiltration is a form of phytoremediation that involves filtering water through a mass of roots to remove toxic substances or excess nutrients. Rhizofiltration is a type of phytoremediation, which refers to the approach of using hydroponically cultivated plant roots to remediate contaminated water through absorption, concentration, and precipitation of pollutants. It also filters through water and dirt. The contaminated water is either collected from a waste site and brought to the plants, or the plants are planted in the contaminated area, where the roots then take up the water and the contaminants dissolved in it. Many plant species naturally uptake heavy metals and excess nutrients for a variety of reasons: sequestration, drought resistance, disposal by leaf abscission, interference with other plants, and defense against pathogens and herbivores. Some of these species are better than others and can accumulate extraordinary amounts of these contaminants. Identification of such plant species has led environmental researchers to realize the potential for using these plants for remediation of contaminated soil and wastewater. This process is very similar to phytoextraction in that it removes contaminants by trapping them into harvestable plant biomass. Both phytoextraction and rhizofiltration follow the same basic path to remediation. First, plants are put in contact with the contamination. They absorb contaminants through their root systems and store them in root biomass and/or transport them up into the stems and/or leaves. The plants continue to absorb contaminants until they are harvested. The plants are then replaced to continue the growth/harvest cycle until satisfactory levels of contaminant are achieved. Both processes are also aimed more toward concentrating and precipitating heavy metals than organic contaminants. The major difference between rhizofiltration and phytoextraction is that rhizofiltration is used for treatment in aquatic environments, while phytoextraction deals with soil remediation. Rhizofiltration is cost-effective for large volumes of water having low concentrations of contaminants that are subjected to stringent standards. It is relatively inexpensive, yet potentially more effective than comparable technologies. The removal of radionuclides from water using sunflowers was estimated to cost between $2 and $6 per thousand gallons of water treated, including waste disposal and capital costs. Rhizofiltration is a treatment method that may be conducted in situ, with plants being grown directly in the contaminated water body. This allows for a relatively inexpensive procedure with low capital costs. Operation costs are also low but depend on the type of contaminant. This treatment method is also aesthetically pleasing and results in a decrease of water infiltration and leaching of contaminants. After harvesting, the crop may be converted to biofuel briquette, a substitute for fossil fuel. This treatment method has its limits. Any contaminant that is below the rooting depth will not be extracted. The plants used may not be able to grow in highly contaminated areas. Most importantly, it can take years to reach regulatory levels. This results in long-term maintenance. Also, most contaminated sites are polluted with many different kinds of contaminants. There can be a combination of metals and organics, in which treatment through rhizofiltration will not suffice. Plants grown on polluted water and soils become a potential threat to human and animal health, and therefore, careful attention must be paid to the harvesting process and only non-fodder crop should be chosen for the rhizofiltration remediation method.

Copper Mining
 
01:12
Mining is a very serious environmental issue. First of all, when a mine is dug, the workers have to destroy the land that is there to make a hole. Also, when the mine is dug, the minerals that are found there release gasses that pollute the air. Water is polluted by: chemicals that the mine releases, by the waste and by the soil runoffs. Soil is polluted by the same chemicals, and by the polluted water that gets into it. Mining is an issue because we can't stop using copper; because we need copper for every single electrical device. People can help solve this issue by recycling copper; so instead of dumping your old T.V. in the trash, recycle it, take out the copper wires and other parts that still work, and use them to make a new television. The only problem with that is that copper wire recycling machines can cost up to a million dollars. If we want a recycling center, or a place where people can recycle their electrical devices, a lot of machines would be needed for that, which means that a lot of money would be needed.

ECOLOGICAL ASPECTS—PROTECTION OF SURFACE AND UNDERWATER ENVIRONMENTS This lecture provides an overview of what scuba diving businesses can do to achieve environmental sustainability goals, including the promotion of ecological awareness among staff and clients. Underwater ecosystems are under threat from stressors counting climate change; ocean acidification; eutrophication; pollution; hard and soft engineering; extraction of resources; and diving activities. The resulting impacts can affect the structure and functioning of ecosystems, leading to their degradation or loss. These impacts would also affect the scuba diving industry negatively. Scuba diving business responsibility towards ecological sustainability and awareness is underpinned by actions including: proper training and education; reducing the carbon footprint; active promotion of environmental awareness top-down; reducing pollution and litter; actively protecting dive sites; not selling endangered species; collaborating with local businesses for the promotion of sustainable initiatives; and collaborating with governance bodies. Staff are a critical interface between the client, the environment, and the diving business. Businesses need to properly form their staff so that these can be aware of environmental responsibility, and be capable of imparting this awareness to the clients. This can be achieved through properly training the hired staff in diving skills; environmental education of staff; active promotion of environmental awareness; training on appropriate interfacing with clients; intervention upon misconduct; motivation and empowering; and role modeling. The best practices adopted by dive businesses and staff can impact positively on the clients. Key steps to follow in order to create long-lasting environmental awareness among clients include: displaying clearly all the rules that apply to the diving practice and the business’s philosophy; education and briefing; intervention upon misconduct; eco-friendly marketing; involvement; role modeling; and asking for feedback. The primary benefit of embracing eco-friendly philosophies is the guarantee that ecosystem services provided for diving can continue to exist and be delivered. Without healthy and functioning ecosystems, dive sites cannot attract tourism, and cannot sustain the livelihoods of people who depend on the diving industry.
