Letching meaning

One solution proposed to reclamation problems is the privatization of the land to be mined Woody et al. As of cushion fabrics, which could reduce potential punctures and their leaking, were still being debated due to their tendency to increase risks if too much weight on too large a surface was placed on the cushioning Thiel and Smith While the highest concentrations have stayed near the buffer zones of the mine and in the East Finniss River, those that did make it into the Finniss River pose a serious and ongoing public threat to those living nearby who used the river daily Ferguson et al. This can be amplified over time. Nickel recovery from the leach solutions is much more complex than for copper and requires various stages of iron and magnesium removal, and the process produces both leached ore residue "ripios" and chemical precipitates from the recovery plant principally iron oxide residues, magnesium sulfate and calcium sulfate in roughly equal proportions. Both oxide and sulfide ores can be leached, though the leach cycles are much different and sulfide leaching requires a bacterial or "bio-leach" component.

Letching meaning


In leaching both heap leaching and in-situ leaching produced 3. The simplest in design, conventional pads are used for mostly flat or gentle areas and hold thinner layers of crushed ore. Examples[ edit ] Rum Jungle Mine[ edit ] One of the oldest and most famous uranium mines in the world, the Rum Jungle Mine in Northern Territory , Australia was constructed in the s, and is today experiencing extreme amounts of environmental degradation and acid rock drainage that are leading to further negative impacts on the surrounding river and ecosystems Ferguson et al. Although the leaks happened in the s, and the mine was eventually shut down in , health problems on the reservation persist, and as not all of the mine was properly cleaned up, could potentially cause further damage to the people of Fort Belknap Woody et al. However, it is often difficult to match corporate mining interests with local social interests, and money is often a deciding factor in the successes of any disagreements. Valley Fills are pads situated at valley bottoms or levels that can hold everything falling into it. Copper ores[ edit ] The method is similar to the cyanide method above, except sulfuric acid is used to dissolve copper from its ores. Alternative locations must be analyzed in mining proposals, as well as rehabilitation plans, externalities and possible solutions , groundwater and infrastructure changes, gained or lost opportunities, socio-economic impacts, and risks, as well as measures taken to reduce or eliminate the risks Department of Natural Resources, Environment, the Arts and Sport Reclamation bonds are required. Rio Tinto is commercializing this technology in Namibia and Australia , the French nuclear power company Areva in Niger two mines and Namibia, and several other companies are studying its feasibility.

Nickel recovery from the leach solutions is much more complex than for copper and requires various stages of iron and magnesium removal, and the process produces both leached ore residue "ripios" and chemical precipitates from the recovery plant principally iron oxide residues, magnesium sulfate and calcium sulfate in roughly equal proportions. As of cushion fabrics, which could reduce potential punctures and their leaking, were still being debated due to their tendency to increase risks if too much weight on too large a surface was placed on the cushioning Thiel and Smith Now, years later, it is still posing a serious environmental risk to those around the mine Mudd and Patterson If these lands can be planted with vegetation that can survive more acidic conditions, however likely that may be, they may be able to avoid eroding materials into other, less mine-contaminated ecosystem Riley The final product is cathode copper. A byproduct is iron II sulfate , jarosite , which is produced as a byproduct of leaching pyrite , and sometimes even the same sulfuric acid that is needed for the process. These leach pads caused considerable contamination to soils as chemicals seeped through them. Cultural and Social Concerns[ edit ] With the rise of the environmentalist movement has also come an increased appreciation for social justice, and mining has showed similar trends lately. Given the likelihood of this, though, more rehabilitation measures are being sought after. There currently are no operating commercial scale nickel laterite heap leach operations, but there is a sulphide HL operating in Finland. Both oxide and sulfide ores can be leached, though the leach cycles are much different and sulfide leaching requires a bacterial or "bio-leach" component. Ranger Uranium Mine[ edit ] The Ranger Uranium Mine in Northern Australia showed a significant increase in erodibility of lands when in contact with materials treated from chemical mining Riley Currently, mining on federal land must have a government-approved mining and reclamation plan before mining can start. Dump leach pads hold more ore and can usually handle a less flat terrain. Societies located near potential mining sites are at increased risk to be subjected to injustices as their environment is affected by the changes made to mined lands—either public or private—that could eventually lead to problems in social structure, identity, and physical health Franks
