Abstract

The invention discloses a feldspar quarry beneficiation process which includes conducting breaking and grinding on feldspar quarry raw ore, adopting SLon magnetic separators to conduct strong magnetic separation and weak magnetic separation, then conducting secondary floatation to obtain feldspar concentrate with the content of Fe2O3 smaller than 0.1%. The beneficiation process is characterized in that under the condition that the raw ore is ground to certain fineness, a weak SLon magnetic separator and a strong SLon magnetic separator are sequentially adopted to conduct magnetic separation, then floatation is conducted under the specific process condition to enable the content of iron in the feldspar quarry raw ore to be reduced to below 0.1% to obtain good feldspar quarry and reach the use standard in the glass industry. The process turns waste into wealth, adopts the mode that magnetic separation is conducted first and then floatation is conducted, the content of medicament added later is greatly reduced, the pollution is small, and the cost is lower.

Description

technical field [0001] The invention relates to the field of chemical metallurgy, in particular to a feldspar ore beneficiation process. Background technique [0002] Feldspar is the most widely distributed rock-forming mineral in the earth's crust, accounting for about 50% of the total weight of the earth's crust; it is an anhydrous framework silicate of potassium, sodium, calcium and barium; rich in potassium feldspar (KAlSi 3 o 8 ), albite (NaAlSi 3 o 8 ) Mineral feldspar mineral products are not only used as the main raw material of glass industry and ceramic industry, but also widely used in chemical industry, abrasive abrasives, glass fiber and other industrial sectors; however, natural high-quality feldspar raw materials are facing resource depletion, while ordinary With high iron content, feldspar raw material resources that cannot be directly used in industrial production are very rich. [0003] At present, the domestic feldspar processing industry usually adopt...
