barite as a gangue mineral in hydrothermal veins

Barite Mineral Physical

Barite Mineral Physical

A gangue mineral in lowtemperature hydrothermal veins; in residual deposits from weathered baritebearing limestones; an accessory mineral in igneous rocks; in carbonatites; a primary component of submarine volcanogenic massive sulfide deposits and seafloor chimneys. Uses Area. Barite is the main ore of the element barium.

Therefore, the oxidation of minor sulfide minerals in barite veins may be prone to acid mine generation and of environmental concern. The inhalation of silica dusts released by silicarich barite ores (20% SiO 2 ) during crushing, milling, as well as using in drilling mud may trigger silicosis.
