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.

2.1 Potential-Determining Ions. The surface charge in systems of importance to mineral processing may arise from a variety of different sources. In the case of ionic solids, such as BaSO 4, CaF 2, CaCO 3, and AgI, the surface charge arises from a preference of one of the lattice ions for sites at the solid surface in comparison to the …

Dense medium separation (DMS) is often used to reject a large portion of gangue material upfront to create cost and energy savings during processing. As lower-grade ores with complex mineralogy are being increasingly exploited, the properties of the gangue minerals begin to play a more important role in the upgrading of the ore. It is …

But within the mine, maybe only 2 percent of the rock we mine is valuable mineral and the other 98 percent is waste. In order to do the separation between the valuable minerals and the waste minerals, we need to grind them very finely down to, let's say less than a tenth of a millimetre before we can do the separation. This is called …
