Baryte Mining Process Equipment Flow CasesJXSC
Baryte Mining usually applies wet magnetic separation to beneficiate some iron-bearing mineral like siderite which applies to barite ore that is used in barium-based medicine requiring low iron barite. Floatation As for the barite with fine particle size and gravity tailings JXSC Mining applies the process of floatation.

Sulfate Discharge Measurement Removal Saltworks
In mining metals are often extracted from minerals containing sulfur and processing results in oxidation to sulfates. Although not generally very dangerous to humans moderate levels (250–500 mg/L) of sulfates in drinking water are associated with an undesirable taste and higher levels can cause illnesses such as diarrhea (>1 000 mg/L).

SulfatesLenntech
Reverse osmosis (RO) is a water treatment system that eliminates most dissolved elements and chemicals such as sulfate from water by pushing the water through a plastic surface similar to cellophane known as a "semipermeable membrane." Generally it can eliminate between 93 and 99 of the sulfate in drinking water. This depends on the type of unit.
