Abstract
The invention relates to a method for improving the silver recovery rate of silver concentrate by improving separation concentration. The method comprises press filtering stirring and floating, the grade of silver of zinc melting acid-leaching slag is 450-550g/t. Through returning tailings obtained after fine selection in floating process and concentrate obtained after first scavenging back into a pulpifying mixing tank, the concentration of the pulpifying mixing tank is improved so as to ensure that the pulpifying concentration of ore pulp in the pulpifying mixing tank can be kept at 38-42% after the ore pulp in the pulpifying mixing tank is added with clear water and press filter solution, thus ensuring that the crude separation concentration in floating is 38-42% so as to improve the recovery rate of silver in the acid-leaching slag.
Description
Technical field
The present invention relates to technical field of smelting, particularly a kind of by improving the method that selected concentration improves the silver preparation concentrate silver raising recovery rate.
Background technology
Contain multiple valuable metals such as silver, gold, copper in the zinc metallurgical process in the acid leaching residue of output.For example, the acid leaching residue of mountain, the mouth of a river, Hunan non-ferrous metal Group Co.,Ltd output in zinc metallurgical process, wherein the grade of Ag is 450～550 g/t.
At present, generally from acid leaching residue, obtain silver preparation concentrate by method for floating, the preceding press cake by two sections press filtration outputs of flotation enters and carries out the pulp stirring after the pulp agitation vat is added clear water, pulp density is 38-42%, then by the stirring of sizing mixing, promote and stir, enter after stirring for slurry and roughly select flotation column and roughly select operation, pulp density is 38-42% when roughly selecting operation, since sweep in the floatation process foam promptly for the first time scavenger concentrate return and enter to behind the slurry agitation vat, the pulp density that can cause starching in the agitation vat descends, and makes that pulp density is reduced to 24-26% by 38-42% when roughly selecting operation.Because pulp density reduces when roughly selecting operation, thereby the silver loss too much in the mine tailing after causing reclaiming, and silver raising recovery rate is not high.For example, the silver-colored grade in the acid leaching residue is 537 g/t, and the concentration of roughly selecting in the floatation process is 25%～30%, silver preparation concentrate silver grade after the recovery is 6712g/t, the rate of recovery 65.59%, productive rate 5.25%, mine tailing silver grade 195 g/t after the recovery, mine tailing silver grade is too high, and silver raising recovery rate is not high.
According to floating principle, the flotation of the high more suitable more employing high density of head grade so not only helps mineral processing index and improves, and also can reduce reagent cost.Proof by experiment, cause the not high major cause of silver raising recovery rate be silver-colored roughing flotation concentration cross low due to.。
