BARITE FROM CERRO HUARIHUYN, PERU

Barite is a major industrial mineral and the source of all barium and barium compounds. Some eight million metric tons of barite are recovered worldwide each year by open-pit mining of barite-rich sandstone. Because of barite’s substantial density, crushed ore is easily concentrated by hydraulic, gravitational-separation methods.

Barite (BARIUM) - Altervista

2012-6-21  Barite (BARIUM) Introduction Barite is a mineral composed of barium sulfate, BaSO 4. It is usually colorless or milky white, but can be almost any color, depending on the impurities trapped in the crystals during their formation. Barite is relatively soft, measuring 3-3.5 on Moh’s scale of hardness. It is unusually heavy for a non-metallic ...

The fine calcined dolomite, ferrosilicon, and fluorspar are weighed in batch lots and mixed in a rotary blender. This mixture is then briquetted in briquetting presses. Briquettes are then conveyed to the reduction furnaces.
