Environmental Risks of Mining

In situ leach (ISL) mining. ISL mining has environmental and safety advantages over conventional mining in that the ore body is dissolved and then pumped out, leaving minimal surface disturbance and no tailings or waste rock (World Nuclear Association, 2012). There is no ore dust or direct ore exposure to the environment and a lower consumption of water is needed in the mining process

In-situ leach Mining, Mineral Mining, Copper

In-situ leach mining entails pumping of a leachate solution into the ore body via a borehole, which circulates via the porous rock dissolving the ore and is extracted by means of a second borehole. The leachate solution differs according to the ore deposit - for salt deposits the leachate may be fresh water into which salts may willingly dissolve. For copper, acids are generally required to

Heap leaching - Wikipedia

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

What is "In Situ" Mining? – Protect Water for

16.03.2017· In situ leach mining (ISL) is a method of uranium mining where hundreds of wells are drilled in a "grid pattern" over an ore body that is located in a groundwater aquifer. Water mixed with sodium bicarbonate concentrate is pumped down into the aquifer, across the uranium ore bed, and them up and out other wells. The mining solution is injected into the aquifer

In situ leaching | Grundfos

In situ leaching or solution mining is a process of recovering minerals such as copper and uranium through boreholes drilled into the formation, without the need for conventional mining. Grundfos can supply submersible and end-suction pumps that ensure the effective pumping of barren or pregnant solutions into the formation and back up to the mineral processing plant.
