Figure 6.5.2.1 6.5.2. 1: Map of world mining areas. Mining is defined as the extraction, from the Earth, of valuable material for societal use. Usually, this includes solid materials (e.g. gold, iron, coal, diamond, sand, and gravel), but can also include fluid resources such as oil and natural gas. Modern mining has a long relationship with ...

Minerals such as potash, trona (raw soda ash), etc., are readily soluble in water thus they could be suitable for solution-mining. In case of these minerals, solution mining targets the dissolution of the so called "evaporates" fraction, which commonly consists of soluble rock material. Essentially, the process consists of pumping water ...

Solution mining is an alternative to mechanical excavation of salt ores (Richner et al. 1992). Since most waste components in solution mining are not soluble they are left behind to settle to the bottom of the expanding cavern, as the brine product is removed to a surface processing facility. Unlike conventional mining, there are no large above ...

strip mining, removal of soil and rock (overburden) above a layer or seam (particularly coal ), followed by the removal of the exposed mineral. The common strip-mining techniques are classified as area mining or contour mining on the basis of the deposit geometry and type.

Solution mining through injection wells is an option that can minimize the environmental footprint and potential impact to surface water compared to more traditional mining processes. To prevent contamination of ground water (which in many cases is a USDW) by Class III wells, more fluid is extracted than is injected in solution mining …

Solution mining is used to recover deep deposits that would be uneconomical using underground methods, but only if the ore can be easily dissolved by a solvent. In this method, holes are drilled from the surface into the deposit. A solvent is pumped down one hole, and the resulting solution with the dissolved mineral is pumped out another hole.
