We are offering dolomite.Dolomite is a double carbonate rock with composition of calcium & magnesium occurring as arhombohedral crystals, proportion varying as per mining zone. Dolomite is harder and denser than the calcite form of calcium carbonate or limestone, and is more chemically inert and more impervious to acid attack. Chemically and structurally it is similar to calcite with half the calcium ions replaced by magnesium.
We are offering mica.Mica describes a group of complex hydrous aluminium silicate minerals. Crystals of mica exhibit perfect basal cleavage and split easily into tough, flexible platelets or sheets. Electrically, mica is fire proof and has the unique combination of high dielectric strength, endurance, uniform dielectric constant, low dielectric loss (or high q), high electric resistivity and superior insulating properties.
We are offering limestone.Limestone is a sedimentary rock composed of the mineral calcite (calcium carbonate). Limestone may be crystalline, clastic, granular, or dense, depending on the method of formation. We have high quality limestone in our mines to produce high quality quick lime and hydrated lime.
