Abstract

The invention discloses a lead-zinc sulfide mineral flotation carbon inhibitor and a process. The carbon inhibitor comprises the following components in parts by weight: 35-65 parts of a flotation agent, 12-23 parts of sugar, 2-5 parts of organic acid and 2-5 parts of vegetable dye. The carbon inhibitor has the effect of inhibiting carbonaceous gangue, carbonate gangue and other minerals, and has very obvious effects of inhibiting carbon and extracting silver, stabilizing foam, inhibiting groove running, eliminating reagent removal and improving the lead-zinc separation effect. According to the method, the influence of high carbon on lead-zinc ore flotation is effectively solved, the first-grade quality of lead-zinc concentrate products is achieved, the associated silver recovery rate is greatly increased, and economic benefits, social benefits and ecological environment benefits are remarkable.

Description

technical field [0001] The invention relates to the field of mineral processing, in particular to a carbon inhibitor for flotation of lead-zinc sulfide minerals and a process. Background technique [0002] Lead and zinc are important non-ferrous metals, which occupy an important position in the development of the national economy. At present, the extraction of lead metal and zinc metal mainly comes from lead-zinc sulfide ore, and galena and sphalerite are the main carrier minerals of lead and zinc metal. However, lead and zinc have common mineralization reasons and similar electronic structures, and to a large extent have the same hydrophilic and hydrophobic properties. In addition, lead and zinc are often closely symbiotic and difficult to completely dissociate, resulting in difficulties in the separation of lead and zinc. Conventional lead-zinc sulfide ores are generally processed through principle processes such as lead-zinc priority flotation, lead-zinc mixed-priority f...
