Calcite is the principal mineral of the rock group known as carbonates. Calcite is a major component in limestone and dolomite. Uses Calcite is the mineral component of limestone which is used primarily as construction aggregates, and in production of lime and cement.
inquiry Precipitation of extensive calcite cement during burial diagenesis can strongly modify the depositional permeability of a sandstone reservoir and affect fluid flow during production. To predict subsurface flow through cemented reservoirs, permeability distributions used in fluid-flow models must reflect this diagenetic overprint.
inquiry Fluorite is an important strategic mineral. In general, fluorite ores will contain a certain amount of calcite gangue mineral. Thus, they need to be separated from each other. For an economic separation, a reverse flotation process is used to float calcite gangue from fluorite. However, little information on the separation is available.

inquiry Effect of depressants in the selective flotation of . calcite have been studied through microflotation. The single mineral flotation tests show that LSC can depress calcite, but it has little effect on flotation. Flotation separation of a mixture of smithsonite smithsonite and calcite can be completed to obtain a zinc concentrate grade up to 33 ...
inquiry With its excellent calcium-chelating ability, PBTCA was used as a novel depressant to selectively separate scheelite from calcite in this study. The flotation results of single mineral, binary mixed minerals, and real ore showed that PBTCA could selectively depress calcite at pH using sodium oleate as collector.
