The genesis of calcite and dolomite carbonatite
When calcite sinks into a region rich in earlier precipitated calcite, this creates disequilibrium crystallization of dolomite and produces calcite–dolomite assemblages. Once the peritectic is bypassed, either in equilibrium or disequilibrium conditions, dolomite is the sole carbonate crystallizing and will lead to the formation of …

It is an essential and major mineral in limestones and marbles, occurs in cave deposits, and occurs as a vein mineral with other carbonates, sulfides, barite, fluorite, and quartz. Calcite also occurs in some rare carbonate-rich igneous rocks and is a common cement in some sandstones. Calcite is an accessory mineral in rocks of many sorts. It ...

Carbonate Replacement Deposits (CRDs) » Geology Science
Carbonate Replacement Deposits (CRDs) are geological formations that result from the replacement of pre-existing carbonate rocks by ore minerals, often metals such as lead, zinc, and copper. These deposits are significant sources of base metals and are of economic importance due to the concentration of valuable minerals within them.

Limestone
Limestone. Composed primarily of Calcite, Limestone appear white or nearly white in color. The mineral is used in cement plants for clinker and cement production.
Reverse calcite flotation applied for the beneficiation of the …
Consequently, the flotation behavior of calcite and quartz with amines must be studied for each deposit and results from other limestone deposits cannot be directly applied to the Queguay Formation. The aim of this work is to evaluate the reverse flotation of a limestone sample from the Queguay Formation.
