Method for comprehensively reclaming quartz vein polymetallic oxidized ore resources

Abstract

The invention provides a method for comprehensively reclaming quartz vein polymetallic oxidized ore resources, which comprises the following steps: firstly, crushing and grinding crude polymetallic oxidized ore, and then carrying out flotation for separating the crushed and ground ore into molybdenum concentrates and ore tailings; secondly, alkaline-leaching the molybdenum concentrates with the pH value of 11-14 for forming leaching residue and leaching solution, adopting the carbon-in-pulp process for extracting rough gold from the leaching residue, and carrying out flotation on the ore tailings after the extraction for obtaining lead concentrates; thirdly, extracting the leaching solution in the step two, adding medicaments into the residual extract liquor, reclaiming ammonium rhenium acid, back-extracting the extract liquor, and then forming ammonium molybdate by acid precipitation; and fourthly, carrying out gravity separation to the ore tailings in the step one for obtaining quartz concentrates and the ore tailing, acid-washing the quartz concentrates for obtaining arenaceous quartz, and discharging the ore tailings. The method adopts the manners of separating step by step and extracting layer by layer, integrates a plurality of processes, and fully reclaiming valuable metals such as gold, molybdenum, lead, rhenium and the like, so the comprehensive utilization rate of the ore is over 80 percent.

Description

technical field

[0001] The invention relates to a method for comprehensive recovery of quartz vein polymetallic oxide ore resources, which belongs to the technical field of mineral processing. Background technique

[0002] At present, the existing technologies in the field of mineral processing are all developing and researching on primary ore, and the development of primary ore is relatively mature, because primary ore has the characteristics of easy mineral processing, high enrichment ratio, simple process, and low cost. Compared with primary ores, polymetallic oxide ores have a high oxidation rate and serious muddying, making it difficult to concentrate and collect, which is a major technical problem at home and abroad. In addition, due to the low grade of ores, they cannot be directly used, so they are all regarded as " "Stay ore" treatment or direct abandonment cannot produce economic benefits. At present, there is still no effective method to recover various metals in ...
