The invention discloses a complex carbon-containing lead-zinc ore collaborative beneficiation method. A low-alkali saline water collaborative beneficiation technological process of partial decarburization, preferential lead selection, lead middling regrinding, efficient copper extraction of lead concentrate and rapid and asynchronous zinc flotation of lead tailings is adopted. The method has the advantages of high recovery rate, low cost, simple technical line and easy industrial application, and is favorable for improving the technological content and comprehensive competitiveness of the nonferrous metal industry.
Description
technical field [0001] The invention relates to the technical field of mining and metallurgy, and the invention relates to a complex carbon-containing lead-zinc ore synergistic beneficiation method. Background technique [0002] The distribution areas of complex carbon-containing lead-zinc deposits in my country mainly include Sichuan, Inner Mongolia, and Guangxi. There is a Canyan produced from Canyan once. Its ore properties have the following characteristics: ① carbonaceous ores need to recover many types of minerals, most of which contain high pyrite content, and most of the zinc minerals are sphalerite. ②The ore has high carbon content, different degrees of carbonization, different buoyancy of carbon, and carbon is closely connected with useful minerals and gangues. ③ Carbon-containing, lead-zinc polymetallic ores are embedded with fine particle size, and the useful minerals have close symbiotic relationship and complex structure. The inclusions and fused bodies of an...
