Description
Известные способы обесцинковани свинцовых концентратов, основанные на подавлении свинцовых и флотации цинковых минералов, заключаютс в применении в качестве лепрессора свитово- минепп (галенита) смеси хромпика и извести или смеси сульфита и сернокислого железа. Однако эти способы недостаточно эффективны.Known methods of de-zincing of lead concentrates, based on the suppression of lead and flotation of zinc minerals, consist in using as a lepressor svitovominepp (galena) a mixture of chromium and lime or a mixture of sulphite and iron sulfate. However, these methods are not effective enough.
Описываемый способ заключаетс в том, что концентрат или полупродукт перемешивают с хромпиком и сульфитом или сернистой кислотой, после чего производ т флотацию сфалерита.The described method consists in mixing the concentrate or intermediate with chrompeak and sulfite or sulfuric acid, after which the sphalerite is floated.
Применение способа обеспечивает более высокую степень разделени свинцовых и цинковых минералов и, кроме того, позвол ет обходитьс без медного купороса, который используют дл активации цинкового минерала (сфалерита) и без подогрева пульпы.The application of the method provides a higher degree of separation of lead and zinc minerals and, in addition, allows avoiding copper sulfate, which is used to activate the zinc mineral (sphalerite) and without preheating the pulp.
Сульфит и хромпик можно подавать в процесс и без предварительного смешивани . В этом случае наблюдаетс менее высока степень разделени .Sulfite and bromic can be fed into the process without prior mixing. In this case, the degree of separation is less high.
Если свинцовый концентрат был получен при значительном расходе коллектора, то перед обесцинкованием необходимо произвести десорбцию коллектора.If lead concentrate was obtained with a significant consumption of the collector, then before dezincing, it is necessary to desorb the collector.
Применение аэрации после десорбции в известковой среде позвол ет устранить депрессируюшее вли ние на сфалерит остатка сернистого натри , примен емого дл десорбции.The use of aeration after desorption in a lime medium makes it possible to eliminate the depressive effect on sphalerite of the sodium sulphide residue used for desorption.
Автором приведены результаты лабораторных опытов, подтверждающие эффективность описываемого способа (см. таблицу).The author presents the results of laboratory experiments, confirming the effectiveness of the described method (see table).
