Acid leaching PTMS MAGNETIC SEPARATOR Iron removal method is mainly the use of quartz insoluble in acid (except hydrofluoric acid), other impurity minerals can be dissolved by acid characteristics, so as to achieve further purification of quartz sand. Acid leaching method can not only remove iron from quartz sand, but also have a good effect on non-metallic impurity minerals.
Acid leaching PTMS MAGNETIC SEPARATOR mainly includes single acid leaching method and mixed acid leaching method. The single acid leaching method is mainly for quartz sand with relatively simple impurities. Mixed acid leaching method is to mix different acids together to collaboratively remove various impurities in quartz sand, which has higher removal efficiency and better product purity.
PTMS MAGNETIC SEPARATOR commonly used acids include sulfuric acid, hydrochloric acid, nitric acid and hydrofluoric acid, etc. Oxalic acid, which is less harmful to the environment, is also used for iron removal. The main factors affecting the acid treatment effect include quartz sand particle size, acid concentration, temperature, time, and the mixing ratio of various acids, and the time of delivery.
