Description
Дл извлечени медных и цинковых минералов и отделени последних от сульфидов железа исиользуют высокощелочную среду, ири которой подавленный пирит остаетс в хвостах. Эти хвосты подвергают в дальнейшем сгущению и перефлотации. Однако из-за больщой остаточной щелочности хвостов при их перефлотации расходуетс значительное количество реагентов и не обеспечиваетс возможность получени высококачественного конечного продукта (пиритного концентрата ) с высоким содержанием серы.In order to extract copper and zinc minerals and separate the latter from iron sulfides, a highly alkaline medium is used, and the suppressed pyrite remains in the tails. These tails are further condensed and re-flotation. However, due to the large residual alkalinity of the tails, during their re-flotation, a significant amount of reagents are consumed and the possibility of obtaining a high-quality final product (pyrite concentrate) with a high sulfur content is not ensured.
Предлагаемый способ получени пиритного концентрата более совершенен по сравпению с известными подобными способами, так как при использовании его обеспечиваетс повышение качества концентрата . Это достигают применением при флотации хвостов кремнефтористого натри , служащего дл активации пирита, задепрессированного известью .The proposed method for the preparation of pyrite concentrate is more perfect in comparison with known similar methods, since using it provides an increase in the quality of the concentrate. This is achieved by the use of sodium fluorosilicate tailings during flotation, which is used to activate pyrite, depressed with lime.
По предлагаемому способу при флотационной переработке хвостов циклов флотации цветных металлов на медных, медно-цинковых и полиметаллических обогатительных фабриках, которые примен ют известь в качестве реагента-регул тора щелочности пульпы и подавител флотации пирита, используют кремнефтористый натрий. Флотаци пирита с помощью кремнефтористого натри осуществл етс в слабощелочной среде.According to the proposed method, in flotation processing of the tailings of the flotation cycles of non-ferrous metals to copper, copper-zinc and polymetallic processing plants, which use lime as a reagent for regulating the alkalinity of the pulp and suppressor of flotation of pyrite, sodium silicofluoride is used. Pyrite flotation with sodium silicofluoride is carried out in a weakly alkaline medium.
Применение кремнефтористого натри активизирует флотацию пирита , задепрессированного известью. При этом флотационное выделение его осуществл етс в услови х, более благопри тных по сравнению с другими известными способами, так как устран етс коррози аппаратуры и выделение синильной кислоты.The use of sodium silicofluoride activates the flotation of pyrite, depressed lime. At the same time, the flotation separation of it is carried out under conditions more favorable as compared with other known methods, since the corrosion of the apparatus and the release of hydrocyanic acid are eliminated.
