Quartz/Quartz Mining

A common silica mineral found in all kinds of rocks and mineral veins and in many primary gold deposits. Such deposits were formed when siliceous liquids bearing gold were forced up through fissures in the earth’s crust, where they cooled to form lodes or veins. Auriferous quartz deposits account for a significant number of mining operations, particularly in Canada. In South Africa, gold is extracted from a quartz-pebble conglomerate of the Witwatersrand Basin.
