Description

The invention relates to the enrichment of minerals, in particular to the flotation of potash ores containing clay-carbonate impurities, and can be applied to existing potash plants processing ores by the flotation method.

The purpose of the invention is to increase the recovery of clay-carbonate sludge

due to the increased flotation activity, a concomitant increase in the extraction of NO, in the putter, while simultaneously reducing the stability of the foam.

The composition of the emulsope EGT includes, wt.%:

swelling product by 3.0-5.0%, and also as a result of more effective flotation of potassium chloride, a decrease in its loss by 0.6-2.4%.

Higher flotation results compared with the known method are achieved by applying the additive emulsol EGT, taken at a ratio of ethoxylated fatty acids with emulsol EGT 1: 0.02-1.5.

The rate of destruction of the flotation foam increases with an increase in the emulsol content.

Example. In the flotation bullet-25 formula of the invention, the solution was introduced sequentially

polyacrylamide - 40 g / t of ore (time-flotation method of clay-carbonate mixing for 30 s), a solution of spam from potassium-containing ores,

including, a preliminary fraction of 500 g / t of ore (mixing time 30 s) and emulsol EHT 500 g / t of ore (mixing time 30 s).

It is possible to co-administer oxyethylated fatty acids from emulsion-35 carbonate Nshamov by enhancing the salt EGT in the form of an emulsion. After this () sootactivating of the collector, the clay-carbonate spam is floated for one minute during one minute.

In this way
