Способ относитс к обогащению полезных ископаемых, в частности к флотационному обогащению горючих сланцев .The method relates to the enrichment of minerals, in particular to the flotation enrichment of combustible shale.
Известен способ получени концентратов керогена из горючих сланцев, включающий измельчение, разделение исходного продукта на пески и шламы, кондиционирование в присутствии реагентов, основную контрольную и перечистную флотацию ij.A known method for producing kerogen concentrates from combustible shale, including grinding, separation of the initial product into sands and sludges, conditioning in the presence of reagents, the main control and clean-up flotation ij.
Недостатком известного способа вл етс невысокое извлечение керогена в концентрат.The disadvantage of this method is the low extraction of kerogen into the concentrate.
Цель изобретени - повышение извлечени керогена.The purpose of the invention is to increase the recovery of kerogen.
Цель достигаетс тем, что в кондиционирование в качестве реагента ввод т обесфеноленный педистиллированный легкосредний конденсат полукоксовани горючих сланцев, содержащий , вес.% углеводороды 61,5-63, карбонил- и гидроксилсодержащие соединени 37-38,5.The goal is achieved by introducing defenolated, pedistilled, light-medium condensate of semi-coking of combustible shale, containing, by weight,% hydrocarbons 61.5-63, carbonyl and hydroxyl-containing compounds 37-38.5.
Пример. Цульпу, содержащую измельченный до 95% класса минус 0,074 мм горючий сланец, раздел ют) в гидроциклоне на пески и тламы. Шламы (содержание керогена 45-47%) и пески (содержание керогена 18-20%) перед флотацией обрабатывают дбесфеноленным недистилпированным легкосреднИм конденсатом полукоксовани горючих сланцев (к.к. 170С, до ЗбОС выкипает 42-44%) при обшем расходе 1500-2000 г/т, вспениватель ИМ-68 затем флотируют по схеме, включающей основную флотацию, контрольную флотацию и три перечистные Example. The pulp containing crushed shale crushed to 95% class minus 0.074 mm is divided into sands and tlamas in a hydrocyclone. Sludge (content of kerogen 45–47%) and sand (content of kerogen 18–20%) before flotation are treated with non-phenolic non-distilled light-intermediate condensate of semi-coking of combustible shale (q. 170 C, to Zbos boils 42-44%) at a total consumption of 1500–2000 g / t, the blowing agent IM-68 is then floated according to a scheme that includes main flotation, control flotation and three cleaner
15 операции, причем промежуточные продукты первой, второй перечисток-и концентрат контрольной флотации шламового цикла направл ют на основную флотацию песков, а промежуточный 15 operations, with the intermediate products of the first, second cleaning out-and concentrate of the control flotation of the sludge cycle directed to the main flotation of sand, and the intermediate
20 продукт третьей перечистки nujaMOBOго цикла направл ют на основную флотацию шламов.20, the product of the third cleaning of the nujaMOBO cycle is directed to the main flotation of sludges.
