Ore processing plant means that extracts and purifies some elements in the raw ore through a series of complex ore beneficiation flow and professional beneficiation equipment. The refined concentrate powder is mainly used in metallurgy and industry base.
In this plant, gold ore is mainly natural gold among the ore to be processed, but it is mostly distributed in the crack of poisonous sand, pyrrhotite and quartz crystal gap, which significantly improves the processing difficulty of the gold ore. The custo
Related Equipments: two PE600×900 jaw crushers, two impact crushers, two cone crushers, two sand makers and three circular vibrating screens.
Calcium carbonate is the main raw material to make cement, lime and calcium carbide, and it is an indispensable flux limestone in metallurgical industry.
Limestone is mainly composed of calcium carbonate (CaCO3), MO's Hardness 3 degrees. The limestone particles or powders can be used in building materials, road construction, metallurgy, chemical and other industries after crushing or grinding.
Gold ore whose types of deposits are diverse and complex is the mineral assemblage of gold. With features of chalcophile affinity and high melting point, the gold ore includes conglomerate type, porphyry type, quartz vein type and volcanic rock type, etc.
