Mine - Kunooz GypsumKunooz Gypsum

Generally top slicing is adopted for mining, wherein road leading from entry point of the deposit is prepared and mining is progressed from top to bottom in slices equivalent to the bench height. Face height varies from 10m down to 2m, dependent on gypsum bedding width. The gypsum beds are followed by 0.5 to 2m of dolomite/limestone.

Dolomite and dolomitization model - a short review

2018-7-13  Dolomite types On the basis of the mode of formation, dolomites can broadly be divided into two groups: primary dolomite and secondary dolomite.2 Primary dolomite precipitate directly from aqueous solution, mostly at or near room temperature (20-35oC), with no CaCO 3 dissolution involved.3 However, dolomite can also form as a secondary phase

What is Gypsum. Gypsum is a soft sulfate mineral, composed of calcium sulfate dihydrate. Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO4 2H2O) is very similar to Anhydrite (CaSO4).
