Abstract
1. Способ флотационного разделении коллективного свинцово-медного концентрата, включающий кондиционирование пульпы, содержащей сульфиды свинца и меди, в щелочной известковой среде с пероксидом водорода, бихроматом щелочного металла, вывод халькопирита в пенный продукт и вывод галенита в камерный продукт, отличающийся тем, что, с целью повышения извлечения свинца в свинцовый концентрат, повышения качества свинцового и медного концентратов, кондиционирование с бихроматом щелочного металла осуществляется после добавления дополнительного депрессора и создания специальных условий для эффективной депрессии флотации галенита. ! 2. Способ по п.1, заключающийся в том, что рН флотации создается добавлением извести в количестве обеспечивающем рН=9-11. ! 3. Способ по п.1, заключающийся в том, что собиратель в основную медную флотацию не подается. ! 4. Способ по п.1, заключающийся в том, что в качестве дополнительного депрессора применяется пероксид водорода. ! 5. Способ по п.4, заключающийся в том, что применяемый в качестве дополнительного депрессора пероксид водорода добавляется в количестве 30-200 г/т руды. ! 6. Способ по п.5, заключающийся в том, что применяемый в качестве дополнительного депрессора пероксид водорода подается перед бихроматом щелочного металла. ! 7. Способ по п.1, заключающийся в том, что после пероксида водорода для депрессии флотации галенита подается бихромат щелочного металла. ! 8. Способ по п.7, заключающийся в том, что бихромат щелочного металла добавляется в количестве 0,05-1,2 кг/т руды. 1. The method of flotation separation of a collective lead-copper concentrate, including conditioning pulp containing lead sulfides and copper in an alkaline calcareous medium with hydrogen peroxide, alkali metal dichromate, output of chalcopyrite into a foam product and output of galena into a chamber product, characterized in that, in order to increase the extraction of lead in lead concentrate, improve the quality of lead and copper concentrates, conditioning with alkali metal dichromate is carried out after adding additional th depressor and creating special conditions for effective depression of galena flotation. ! 2. The method according to claim 1, which consists in the fact that the flotation pH is created by adding lime in an amount providing pH = 9-11. ! 3. The method according to claim 1, which consists in the fact that the collector in the main copper flotation is not supplied. ! 4. The method according to claim 1, which consists in the fact that hydrogen peroxide is used as an additional depressant. ! 5. The method according to claim 4, which consists in the fact that hydrogen peroxide used as an additional depressant is added in an amount of 30-200 g / t of ore. ! 6. The method according to claim 5, which consists in the fact that hydrogen peroxide used as an additional depressant is supplied before the alkali metal bichromate. ! 7. The method according to claim 1, which consists in the fact that after hydrogen peroxide for depression of flotation of galena, alkali metal dichromate is supplied. ! 8. The method according to claim 7, wherein the alkali metal bichromate is added in an amount of 0.05-1.2 kg / ton of ore.
