The Mining effects and green solutions Mining has several environmental impacts that people around the globe are surprisingly ignorant about Erosion groundwater depletion and also loss of biodiversity is caused by the mining effect Moreover there are several chemicals that blend with the surface water during this process

Recovery and dilution usually are interrelated with some methods of stoping a high recovery involves contamination of the ore from the walls or capping and often clean ore can be obtained only by leaving some ore in the mine In open stope mines the greatest loss of ore is that tied up in pillars left for support of the back or hanging wall

Heap leaching is an industrial mining process used to extract precious metals copper uranium and other compounds from ore using a series of chemical reactions that absorb specific minerals and re separate them after their division from other earth materials Similar to in situ mining heap leach mining differs in that it places ore on a liner then adds the chemicals via drip systems to the

Among the major concerns about open pit mining are the change in landform the generation of an acid mine drainage and the deprivation of water supply All these however can be reversed mitigated if not totally avoided with the proper engineering solutions using advances in technology

 · Open pit mining does offer some advantages over traditional deep shaft mining Pit mining is more cost effective than shaft mining because more ore can be extracted and more quickly The working conditions are safer for the miners because there is no risk of cave in or toxic gas Open pit mining is the preferred

Mining Part 3 In his three part series Dr Buck Emberg presents a balanced examination of both the need for mining and the environmental consequences of extracting minerals He explains that mining has been a human activity since before the Stone Age and will remain so in the future He contends that mining is here to stay and we must learn to live with mines and mining companies must learn
