Silica Sand Flotation

Silica Sand Processing & Sand Washing Plant Equipment

The “Sub-A” Flotation Machine has been very successful for silica sand flotation because it will efficiently handle the fast settling sand and move it along from cell to cell positively. Aeration, agitation and selectivity due to the quiet upper zone can be carefully regulated to produce the desired separation.

What Is Sand Mining Process

According to the different minerals density in the silica sand, gravity separation is used to remove the heavy minerals to lower the iron content. Flotation The flotation process is primarily used to remove the iron bearing heavy minerals in silica sand.

Silica / Glass Sand | ArrMaz

Silica sand deposits are most often surface-mined in open pit operations but dredging and underground mining are also used. For industrial applications, deposits of silica yielding products of at least 95% quartz (SiO 2) are preferred. The production of such high purity sand requires that the extracted ore undergo significant processing to reduce impurities through the flotation of gangue minerals such as iron, aluminum and magnesium away from the silica.
