iron separator machine

Acid leaching iron is the use of quartz insoluble in acid (except HF), and the impurity minerals containing Fe can be dissolved by acid solution, so as to achieve the purpose of removing iron-containing minerals from quartz sand. PTMS Electromagnetic Separator Acid immersion method can remove iron-containing minerals in quartz sand, but also has a good removal effect on other non-metallic impurity minerals in quartz.

PTMS magnetic separation

The general commonly used acids are sulfuric acid, hydrochloric acid, nitric acid, hydrofluoric acid, etc., but the price of these acids is high, and has a great impact on the environment. Using oxalic acid as leaching agent to remove iron in quartz sand minerals, is the use of oxalic acid and the surface of Fe3 + reaction to form complex dissolved in water to achieve PTMS Electromagnetic Separator iron removal purpose,

In this case, the dissolution mechanism of iron is different from that of inorganic acids. Its main advantage is that the soluble complex formed during leaching can be decomposed under the action of microorganisms and sunlight. High pure quartz sand with SiO2 purity of 99.99% and Fe content of 235ppm can be obtained with PTMS Electromagnetic Separator.
