Baryte occurs in a large number of depositional environments, and is deposited through a large number of processes including hydrothermal, biogenic, and evaporation. Baryte commonly occurs in lead-zinc veins in limestones, in hot spring deposits, and with hematite ore, anglesite and celestine.
Barytes quarry, qarytes crusher and qarytes separate from zinc
The ore from the barites quarry was first dumped on the vibrating screen to screen out lumps of rock that were too large to begin the production process. These would be broken up by stone breakers and returned to the grid.
From beneath the vibrating screen the rock was moved by conveyor belt to the primary crusher - jaw crusher that began the process of reducing the size of the ore particles. Any coarse material was screened out and returned to the jaw crusher.
The finely crushed ore was next delivered to a four compartment jig which made use of the different specific gravities of the different minerals in the ore to separate them out through agitation in water. The heaviest minerals - cadmium and galena - would drop first, followed by pyrite and manganese, then zinc and barytes. Light country rock that remained was destined for the waste tip.
Then the zinc and barytes were crushed or grinded to powder in the ball mill or Raymond mill. The final product, included zinc and barytes, out of mills is crushed again.
To separate the zinc from the barytes, the finely crushed powder next went through a flotation process whereby a carefully calculated mix of oils was added to a slurry of powdered ore and water. The oil was attracted to the zinc mineral particles and was helped to float to the surface through the introduction of gas bubbles into the mix. The bubbles were creamed off from the surface, filtered and dried. The barytes slurry that remained was pumped to a separate flotation cell to begin a similar process.
