Complex Approach to the Development of Potash, Potassium-Magnesium and Salt Deposits

Abstract

Salt minerals of various deposits belong to the sedimentary rocks class. They were formed with the long evaporation of seawater in different geological epochs and therefore consist, as a rule, of salt minerals belonging to chlorides and sulphide of alkali and alkaline-earth metals. Forexample, the Starobinsky deposit is characterized by halogen compounds, and Kalushsky and Stebnikovskoye ones by sulfate salts. In addition, inBerezniki deposit and in other Russian deposits there are mixed rocks, including various potassium compounds. Taking into account the peculiarities of potash deposits caused by their easy solubility, acomprehensive solution for their development, containing both the conditions for conducting mining operations and the conditions for theenrichment of potassium-bearing ores, will be relevant.
