For the PTMS magnetic separation reduction method of the insurance powder, the amount, reaction temperature, acidity and other parameters of the insurance powder should be strictly controlled, because the process requirements are strict, and the small changes of these parameters may affect the effect of iron removal. Providing a suitable reaction environment for the chemical bleaching reaction, such as the stirring speed and the sealing ability of the reaction vessel, helps to improve the effect of iron removal and whitening.
In the acid immersion hydrogen gas PTMS magnetic separation reduction method, suitable acids (such as hydrochloric acid, sulfuric acid, oxalic acid, etc.) and reducing agents (such as zinc powder, aluminum powder) are selected and their ratio is optimized to ensure that the iron-containing components can be fully converted into soluble Fe² is removed. In the high temperature roasting method, the amount of chlorinated agent (solid chlorine salt or chlorine gas), the amount of carbon reducing agent and roasting temperature and other parameters need to be precisely controlled,
Because this method is very strict on the material and operation control requirements of PTMS magnetic separation equipment. Different chemical bleaching reactions require appropriate reaction time. Too short reaction time may lead to incomplete iron removal, and too long reaction time may cause other side reactions or increase production costs.
