Baryte Baryte occurs in a large number of depositional environments, and is deposited through a large number of processes including biogenic, hydrothermal, and evaporation, among others. Baryte commonly occurs in lead-zinc veins in limestones, in hot spring deposits, and with hematite ore. It is often associated with the minerals anglesite and . Mineral Processing Introduction The general focus of this document will be on metaliferrous ores represented by run-of-mine material described in egory 3 above. An exception to the above discussion of mineral processing arises when the valuable component of the ore is extracted directly by chemical methods.    Read More
