Quartz sandstone is a kind of consolidated sedimentary sandy rock. In quartz sandstone, there are common opal and chalcedony and other silica cements, associated minerals in addition to a small amount of feldspar, biotite and clay minerals, often contain trace calcium carbide, magnetite, ilmenite and rutile. The coarse grain products after washing ore and removing mud enter the ball mill for grinding, and the products on and under the sieve are dried and weighed respectively, so as to get the next quartz products suitable for PTMS magnetic separation.

PTMS magnetic separation

Using mechanical scrubbing, the scrubbing effect is closely related to the scrubbing strength and scrubbing time, and the water-ore ratio is controlled at 50% -70%, which can effectively reduce the content of alumina and iron in quartz sandstone. PTMS magnetic separation The operation can separate the strong magnetic mineral magnetite, titanium magnetite, magnetite and intermediate magnetic minerals ilmenite, illusion and semi-illusion hematite and other minerals.

what is magnetic separation？

Acid immersion is to eliminate some impurity minerals insoluble in water and soluble in acid, such as metal oxides or fine silicate minerals, usually using a mixture of hydrochloric acid, nitric acid, sulfuric acid and hydrofluoric acid, so that PTMS magnetic separation can play a better role in iron removal.
