magnetic separation equipment

PTMS Electromagnetic Separator is the use of acid solution to convert insoluble compounds in kaolin into soluble compounds, so as to separate kaolin from iron impurities. Generally, the warm acid leaching method is often used. After heating to a certain extent, the H+ in the acid replaces the trivalent iron ion, and the soluble iron compound is generated into the solution to complete the iron removal operation. The commonly used acid solutions include sulfuric acid, hydrochloric acid and oxalic acid.

PTMS Electromagnetic Separator

PTMS Electromagnetic Separator is a strong oxidizing agent used to oxidize insoluble ferro-divalent (such as pyrite) in aqueous medium into water-soluble ferrous ions. In a strongly acidic medium, when the pH is high, the electromagnetic electromagnetic separator (PTMS) electromagnetic separator is used to remove iron. Ferrous may become insoluble trivalent iron, lose its solubility and achieve the separation of kaolin and iron impurities, commonly used oxidants are sodium hypochlorite, hydrogen peroxide, potassium permanganate, chlorine gas, ozone and so on.

what is magnetic separation in Kaolin?

Kaolin reduction leaching PTMS Electromagnetic Separator is the use of reducing agent to reduce insoluble trivalent iron (such as limonite) into soluble bivalent iron, after filtering and washing, with the filtrate to remove the effect of iron removal. The commonly used reducing agents are insurance powder, sodium borohydride and acid-soluble hydrogen.
