Study on the Mineralogy of a Marmatite Ore from Dulong
摘要
Abstract
Process mineralogy is conducted on a marmatite ore from Dulong by chemical multi-el-ement analysis, microscopic observation, energy spectrum analysis of mono - mineral chemical components, MLA automated quantitative surveying technique to provide guidelines for marmatite extraction from the ore. The main results are obtained as follows: although the raw ore contains many metallic minerals,the main target minerals are sphalerite accounting for 7.715% and a small amount of hemimorphite;the results of energy spectrum analysis of sphalerite chemical components show that the sphalerite ore contains 12.04% iron and hence belongs to the marmatite; sphalerite has a close symbiosis relationship with pyrrhotite and chalcopyrite; almost 50% of -0.2 mm sphalerite exists as the intergrowth particles, which contains approximate 7% magnetite and 10% pyrrhotite. According to the above conclusion, it is recommended that the low intensity magnetic separation is first used to enrich magnetite and pyrrhotite; the flowsheet of floating copper and in-hibiting zinc is adopted to recover copper-bearing minerals;and a highly effective activator is used to activate zinc-bearing minerals for flotation.关键词
