Description

The invention relates to biotechnology, in particular, to the targeting of iron from synarynite using microorganisms, and can be used in the preparation of feldspar concentrate in ceramic and glass industry.

The purpose of the invention is to increase the yield of feldspar concentrate with an iron oxide content of less than 0.3%,

The miners are ground to (-0.1) - (+0.04) I-IM, the nutrient medium is introduced and

process growing monocultures of fungi at 25-35 C for 60-96 h with a solid-liquid phase ratio (T: W) equal to 1: 10-1: 20, followed by magnetic separation

As a result of this treatment, synonyrite is destroyed by dissolving calcilite and releasing iron minerals from intergrowths, which can be removed more completely and with high selectivity by magnetic separation. In addition, there is:: l
