Embodiment Construction

[0027] In order to make the purpose, technical solutions and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below, so as to facilitate the understanding of the skilled person.

[0028] 1 laboratory test

[0029] 1.1 Test ore preparation

[0030] The test ore is collected from the production ore, that is, the ratio of Jiawula: 10#: 40#: 48#: 3-1#: 76# = 1:1:1:1:1:1, and 150 kg is collected. Crushed to less than 2mm by a laboratory crusher, stirred evenly, and divided into one bag for every 500g ore sample.

[0031] 1.2 Grinding fineness and time

[0032] The test grinding fineness directly determines the production fineness -200 mesh accounts for 60%. Determine the test grinding time required for fineness to -200 mesh accounting for 55% by 4 test grindings. The test grinding was 47% at 2 minutes and 10 seconds, 55% at 2 minutes and 40 seconds, 60% at 3 minutes and 00 seconds, and 65% at 3 m...

Abstract

The invention relates to a beneficiation collecting agent for recycling copper and silver associated with multi-metal vulcanization lead zinc ores and a beneficiation method of the beneficiation collecting agent and belongs to the field of metal ore processing. The beneficiation collecting agent and the beneficiation method have the advantages that the mixed chemical of ammonium dibutyl dithiophosphate and dianilinodithiophosphoric acid and No. 25 aerofloat are used in a mixed manner in the beneficiation of the multi-metal vulcanization ores, adverse effects on lead-zinc indexes are avoided, copper and silver recycling rate is increased greatly, and copper concentrate grade is stable (above 20%); low cost and quick action are achieved, good economic and social benefits can be generated, and promising application prospect is achieved.

Description

technical field [0001] The invention belongs to the field of metal mineral processing, and in particular relates to a collector and a beneficiation method for recovering associated copper and silver from polymetallic lead-zinc sulfide ores. Background technique [0002] As complex polymetallic sulfide ores continue to expand and change with the mining ore body, the grades of copper and silver in the original ore decrease, and the distribution of useful minerals is complicated. In addition, there are many types of copper minerals in the ore, and the useful anti-pollution particle size is fine, The characteristics of close symbiotic relationship, high sulfur content, and easy oxidation of ore reduce the buoyancy of ore. [0003] There are more than 10 kinds of minerals in the five categories of sulfide, oxide, silicate, carbonate and phosphate. Copper exists in chalcopyrite as an independent mineral; zinc exists in sphalerite as an independent mineral; lead exists in galena a...
