water cooling electromagnetic separator

In actual production, because the amount and type of impurities contained in quartz sand, content, occurrence state and product quality requirements are different, a single method may not be able to achieve the purpose of quartz sand PTMS magnetic separator separation and purification, and sometimes a combined beneficiation process composed of several methods is needed. The common mineral processing and purification process of quartz sand is as follows:

PTMS magnetic separator

Flotation method is mainly to remove feldspar, mica and other non-magnetic associated impurities in quartz sand. Quartz sand PTMS magnetic separator flotation method mainly includes fluorine flotation and non-fluorine flotation. Among them, fluorinated flotation is carried out by cationic collector and hydrofluoric acid activator within the range of acidic pH value. Its disadvantage is that fluorinated wastewater has serious environmental pollution and needs to be treated and discharged.

what is magnetic separation method for concentration of ore？

Fluorine-free flotation is to make use of the difference in the structure composition of quartz and feldspar to reasonably adjust the ratio and dosage of mixed cationic and anion collectors, and prioritize the flotation of feldspar to achieve separation by taking advantage of their different Zeta potentials. Generally speaking, after scrubbing, desliming, PTMS magnetic separator and flotation, the purity of quartz can reach 99.3%-99.9%, which can basically meet the demand of industrial sand.
