Description
При обогащении калийных руд, содержащих до 3-5% глинистых шламов, осуществл ют депрессию последних, а при высоком содержании шламов предварительно механически обесшламливают с последующей депрессией остаточных шламов.With the enrichment of potash ores containing up to 3-5% of clay sludge, the latter are depressed, and with a high sludge content, mechanically slime is preliminarily slime followed by depression of residual sludge.
В качестве реагентов-депрессоров примен ют натровую соль карбоксиметилцеллюлоза (КМЦ), смесь кремниевой кислоты с полиакриламидом (ПАА), смесь КМЦ с продуктами гидролиза древесины и т. д.As depressant reagents, sodium carboxymethyl cellulose (CMC), a mixture of silicic acid with polyacrylamide (PAA), a mixture of CMC with wood hydrolysis products, etc. are used.
Недостатком известного способа флотации руд с депрессией шламов вл етс их высока стоимость.The disadvantage of the known method of flotation of ores with depressed sludge is their high cost.
С целью удешевлени процесса и улучшени технологических показателей по предлагаемому способу при флотации калийных руд примен ют в качестве реагента-депрессора коллагено-танидный реагент (КТР).In order to reduce the cost of the process and improve the technological parameters of the proposed method, in the flotation of potash ores, a collagen-tannide reagent (CTE) is used as a depressant reagent.
Предлагаемый реагент получают путем щелочного или кислотного гидролиза отходов переработки краснодубных кож-краснодубной стружки. Данный реагент содержит р д аминокислот, а также растительные и синтетические дубители-таниды.The proposed reagent is obtained by alkaline or acid hydrolysis of waste from the red-tan leather-red carbon chips. This reagent contains a number of amino acids, as well as plant and synthetic tannins-tannins.
Опытными данными установлено, что наиболее оптимальным соотношением реагентов вл етс 150-200 г/т руды. КМЦ и 200 г/т руды коллагено-танидного реагента.Experimental data established that the optimal ratio of reagents is 150-200 g / ton of ore. CMC and 200 g / t of collagen-tannid reagent ore.
Предмет изобретени Subject invention
Способ флотации руд, содержащих глинисто-карбонатные шламы, отличающийс тем, что, с целью удешевлени процесса и улучшени технологических показателей, депрессию глинисто-карбонатных шламов, например в калийных рудах, провод т с применением коллагено-тапидпого реагента с расходом 300-500 г/т руды, а при содержании в руде указанных шламов выше 3%-смесью реагентов КМЦ в количестве 150-200 г/т руды и коллагено-танпдного реагента-в количестве 150-200 г/т руды.The method of flotation of ores containing clay-carbonate sludge, characterized in that, in order to reduce the cost of the process and improve technological performance, the depression of clay-carbonate sludge, such as potash ores, is carried out using collagen-taped reagent with a consumption of 300-500 g / tons of ore, and when the content in the ore of these sludge is higher than 3% mixture of CMC reagents in the amount of 150-200 g / t of ore and collagen-tangda reagent in the amount of 150-200 g / t of ore.
