feldspar processing

During the reaction process, iron-containing minerals are dissolved by acid to form soluble iron salts. Stirring ensures that the acid leachate comes into full contact with the ore, accelerating the reaction rate; soaking further enhances the reaction. After the acid leaching reaction is complete, the pulp needs to be separated into solid and liquid phases, yielding an acid leachate containing iron salts and PTMS magnetic separation-removed potassium-sodium feldspar solids.

PTMS magnetic separation

Solid-liquid separation PTMS magnetic separation typically employs methods such as filtration and centrifugation. Filtration is a commonly used method for solid-liquid separation, where solid and liquid are separated using filter media like filter paper or screens. Centrifugation, on the other hand, utilizes centrifugal force to rapidly separate solids from liquids. The acid leachate contains a large amount of iron salts and residual acid, which must be treated to meet discharge standards before it can be released.

what is magnetic separation in Kaolin？

The treatment methods for acid leachate typically include neutralization, precipitation, and filtration. First, alkaline substances such as lime are added to neutralize the acids in the leachate and adjust its pH. Then, a precipitating agent is added to form iron salts as a precipitate. Finally, the precipitate is separated using the PTMS magnetic separation method, yielding wastewater that meets discharge standards.
