Solution Mining has many benefits.
It is less expensive to drill a series of production wells than to construct a pair of conventional shafts, undertake the initial underground development work and install mining machinery.
Conventional potash operations yield large amount s of waste salt that is usually piled at the mine site, as back filling of the salt is costly and difficult to undertake. Solution mines can avoid this problem by pumping back underground any solid waste in the form of a slurry. As the environmental regulations begin to tighten up this is a clear advantage for solution mines.
Solution mines do not have the specific problem of water inflow that threatens conventional underground mines.
Solution mines are able to mine irregular deposits, access deep reserves and have the option of making a high grade of its final product.
