In many cases, the valuable minerals are mixed with gangue, commercially useless material, and the ore must be separated. The first step of many separation processes is comminution (size reduction) followed by classification (separation by particle size) either for further grinding or the next step, concentration of the ore.

What is Galena? Galena is a lead sulfide mineral with a chemical composition of PbS. It is the world''s primary ore of lead and is mined from a large number of deposits in many countries. It is found in igneous and metamorphic rocks in medium to lowtemperature hydrothermal veins. In sedimentary rocks it occurs as veins, breccia cements, isolated grains, and as replacements of limestone and ...

Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO 3).The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 3 as "calcite".. Other polymorphs of calcium carbonate are the minerals aragonite and will change to calcite over timescales of days or less at temperatures exceeding 300 °C, and vaterite is even ...

The names in the above chart are root names and should be preceded by appropriate terms for any significant feature of the rock. The proper order is color, structure, grain size (sandstones only), minor constituents, cement, and root name.

Normally, a faceted stone breaks during cutting, and the finished gem is much smaller than the originally intended size. Therefore, a cut calcite over 50 carats is extremely rare. Faceted stones cut from material from many localities might turn up, but the lack of scarcity value is not encouraging to potential calcite .
