Sb & Au Occurrence Geochemistry Research And Utilization In Tailings Of Qinglong Antimony In GuiZhou

The major industry constituent of the Qinglong antimony in Guizhou is stibium. There are kinds of paragenetic and associated minerals, such as pyrite, fluorite, gold, coal, etc. Through the data collected showed that only the main industrial constituent antimony (stibnite) was recycled by Qinglong antimony. Plenty of pyrite and fluorite, gold, and many paragenetic and associated components were not conducted comprehensive utilization. Therefore, this paper makes the paragenetic and associated components investigating as a starting point or clues, focus on the distribution of antimony and gold (useful and valuable elements) in the antimony ore tailings and smelting slag of Qinglong antimony.There still have a large number of available sulfide minerals such as antimonite in the tailings reservoir. It should be utilized before it's oxidized. It is raised that there have 33805t Sb metal potential resource and 1590.30kg Au metal potential resource by systematically sampling and analysis in the tailings and slag. It is indicated the potential resources is rich in the tailings of Qinglong antimony.Based on fully study of previous researches in tailings and the researches of Qinglong antimony, makes the tailings reservoir as a key research object, with the way of detail evidence, by using the geochemical methods of pH test, geochemistry of trace element, rare earth geochemistry and phase analysis, carried out the table tailings geochemical characteristics of the environment, including pH, magnetic susceptibility, electrical conductivity and other characteristics of factors, combined analysis of rare earth element analysis, phase analysis and X-ray powder diffraction test, systematically researched the Sb grade and Au content as well as their occurrence in the tailings. It is considered that the environment of Qinglong antimony tailing reservoir is alkaline-oxidation. As tailings buried depth, the hosting minerals of the Sb are obviously different, mainly transformed from sulfide minerals to the oxide minerals and antimonite minerals.With the analysis above, it is believed that there existent a large number of unsorted antimonite in the tailings. The easily sorted and using mineral antimonite has transformed into the hard sorted and using mineral oxide minerals and antimonite minerals by hypergenesis and elevation in the supergene environment. It makes a large waste of resources. Meanwhile, the antimony is a toxic element in the natural environment.
