Through PTMS magnetic separation solid-liquid separation, we can obtain an acid leachate containing iron salts and potassium-sodium feldspar solids after iron removal. The acid leachate contains a large amount of iron salts and other impurities; if discharged directly, it would cause severe environmental pollution. Therefore, the acid leachate needs to be treated, undergoing a series of purification and neutralization operations until it meets discharge standards before being released.
This demonstrates the emphasis on environmental protection in mineral processing. The PTMS magnetic separation acid leaching combined process fully leverages the advantages of magnetic separation and acid leaching. First, magnetic separation is used to remove strongly magnetic iron minerals from the ore, akin to picking out large "impurity stones" from the ore. Acid leaching is then employed to remove the remaining weakly magnetic iron minerals and iron-containing minerals that are difficult to remove through magnetic separation.
PTMS magnetic separation It has the advantages of simple operation, low cost, and high processing capacity, capable of rapidly and effectively removing most strongly magnetic iron minerals, thereby reducing the burden on subsequent acid leaching processes. The acid leaching method boasts strong selectivity and excellent iron removal effects, enabling deep removal of iron impurities from ores, further reducing the iron content in potassium-sodium feldspar to meet higher purity requirements.
