(54).СПОСОБ ОБОГАЩЕНИЕ ШЛАМОВ(54). METHOD FOR ENRICHMENT OF SLUDGE
1one
Изобретение относитс к обогащению полезных ископаемых.This invention relates to the beneficiation of minerals.
Известен способ разделени железосодержащих щламов, включающий классификацию исходного материала по зерну 40 мкм и полиградиентную электромагнитную сепарацию 1.A known method for separating iron-containing slimes, including the classification of the starting material by a grain of 40 µm and polygradient electromagnetic separation 1.
Известен также способ обогащени щламов , включающий измельчение, классификацию , дещламацию и магнитную сепарацию исходного материала 2.Also known is the method of enrichment of sludge, including grinding, classification, delamatization and magnetic separation of the starting material 2.
Недостатком указанных способов вл етс низка эффективность процесса разделени .The disadvantage of these methods is the low efficiency of the separation process.
Цель изобретени - повыщение эффективности процесса разделени .The purpose of the invention is to increase the efficiency of the separation process.
Поставленна цель достигаетс тем, что после классификации провод т реагентную обработку раздел емого материала.This goal is achieved by the fact that after the classification the reagent processing of the material being divided is carried out.
Причем реагентную обработку осуществл ют при рН 7,5 - 8,0, в качестве реагента используют полиакриламид.Moreover, the reagent treatment is carried out at a pH of 7.5-8.0, polyacrylamide is used as a reagent.
При этом магнитную сепарацию провод т при напр женности магнитного пол 10 - 12 кГс, а дещламацию провод т по зерну 20 мкм.In this case, the magnetic separation is carried out at a magnetic field strength of 10–12 kG, and the distillation is carried out over a grain of 20 µm.
Предлагаемый способ осуществл ют следующим образо.м.The proposed method is carried out as follows.
Исходный материал, например гидро;етит , измельчают, классифицируют по зерну 40 мкм. класс 40 мкм подвергают реагентной обработке при рН 7,5 - 8,0, использу в качестве реагента полиакриламид, дещламируют по зерну 20 мкм и обрабатывают в электромагнитном поле напр женностью 10-12 кГс, при этом расход полиакриламида составл ет 75 г/т.The starting material, for example hydro; ethitol, is ground, classified by grain 40 microns. the 40 µm class is subjected to reagent treatment at pH 7.5-8.0, using polyacrylamide as a reagent, and discarded with a grain of 20 µm and treated in an electromagnetic field with a strength of 10-12 kgf, while the consumption of polyacrylamide is 75 g / t.
Проведение реагентной обработки после классификации вызывает интенсивную флокул цию частиц железа, что позвол ет повысить эффективность последующих операций иувеличить извлечение железа в концентрат на 23%.Conducting a reagent treatment after classification causes an intensive flocculation of iron particles, which makes it possible to increase the efficiency of subsequent operations and increase the extraction of iron into concentrate by 23%.
Таки.м образом, проведение реагентной обработки после классификации позвол ет повысить эффективность процесса разделени .In this way, carrying out the reagent treatment after the classification makes it possible to increase the efficiency of the separation process.
