Description

Дл  производстЕза ферросплавов черной металлургии требуютс  Lue литовые концептраты с пониженным еодержаинел кремнекислоты.For the production of ferrous alloys of ferrous metallurgy, Lue requires lite concepts with a reduced content of silicic acid.

Описываемый способ разделени  концептрата, с целью сьп1жепи  содержани  в нем кремнекислоты до 1,2-2%, состоит в том, что полученный при флотации с применением олеиновой кислоты коллективный шеелитовый концентрат подвергаетс  дл  дезактивации силикатов подкислению сол пой или другой кислотой при концентрации 1,5- 2 г/л. При этом олеинова  кислота не переходит в раствор, а остаетс  на поверхности ценных минералов. Благодар  этому, при последующей отмывке кислого раствора до рН 6 флотационные свойства олеиновой кислоты восстанавливаютс  и шеелит , катион которого  вл етс  потенциал-образующим , может быть вновь сфлотирован, а силикаты, сThe 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
