Processing of Silver mine-containing Lead zinc copper Ores
According to preliminary statistics, the silver associated Pb-Zn deposits accounted for 57.4% 34.g% in the copper deposit, quartz vein-type deposits accounted for 1.7%, other 6%.
Associated with lead, zinc copper silver ore beneficiation Is generally the main metal in accordance with process conditions and reagent system for sorting and does not elect a single silver concentrate, Usually silver enriched in lead, zinc, copper concentrate, and then recovered by smelting. However, in the smelting process, the silver in lead concentrates with the main metal into crude lead; Silver in copper concentrate into the matte, the recovery process is simple, low cost, high recovery rate. Silver in the zinc concentrate fire method or the wet process, are incorporated into the slag fuming recovery process complexity, high cost, low recovery rate. Therefore, the dressing should be silver enriched in lead, copper concentrate.
Occurrence and characteristics of Silver mine-containing Lead zinc copper Ores
Silver was independent silver minerals form. Silver and sulfur, copper, lead, tin, antimony, tellurium, selenium, arsenic and other elements in the formation of various compounds in a variety of deposits in common: the argentite a spiral-shaped sulfur Silver Mine, and hui of silver and copper, dark red silver, brittle silver, proustite, sulfur antimony silver and copper, lead Silver Mine of sulfur antimony, stibnite lead Silver Mine, tellurium, silver, selenium Silver Mine.
Various silver minerals, lead, zinc, copper and other sulfide minerals in close quarters, and mostly micro-fine disseminated, its granularity is almost below 0.04 mm, the vast majority of silver mineral particle size of 0.04 to 0.02 mm, the smallest0.001 mm, the particles fine silver mineral with the form of a living body, inclusions, micro body distribution in galena, sphalerite, sulfide copper minerals.
And silver mineral sulphide minerals in the flotation process has become its carrier, silver enrichment of the various concentrate products. Therefore, the mode of occurrence of the silver minerals embedded Bute comprehensive collection of silver have a significant impact.
