SU107651A1 - Method for flotation separation of collective scheelite concentrate - Google Patents

Description

For the production of ferrous alloys of ferrous metallurgy, Lue requires lite concepts with a reduced content of silicic acid.

The described method of separating the concept product, in order to reduce the silicic acid content in it to 1.2-2%, is that the collective scheelite concentrate obtained by flotation using oleic acid is subjected to acidification with salt or another acid at a concentration of 1.5 - 2 g / l. At the same time, oleic acid does not go into solution, but remains on the surface of valuable minerals. Due to this, during the subsequent washing of the acidic solution to pH 6, the flotation properties of oleic acid are restored and scheelite, the cation of which is potential-forming, can be re-floated, and silicates with

The method of flotation separation of collective scheelite concentrate, obtained with the use of oleic acid and containing silicates, is so that, in order to obtain conditioned shealite concentrates with a reduced from 1.2 to 2% silica content, the collective the concentrate is acidified with hydrochloric or other mineral acid. at a concentration of 1.5-2 g / l, washed to pI 6 and subjected to scrubbing without the use of reagents.
