Bosite's new technology and process for processing refractory gold concentrate, all-mud cyanide carbon slurry gold leaching process
The types of gold ore are divided into: placer gold ore, gold-bearing quartz vein ore, silver-rich gold ore, and oxide gold Mines, iron-bearing sulfide gold mines, copper-bearing sulfide gold mines, arsenic sulfide gold mines, antimony-bearing sulfide gold mines, polymetallic sulfide gold mines, telluride gold mines, carbonaceous gold mines, etc. According to the occurrence state of gold in the ore, it can be classified into: independent natural gold, gold in a dispersed state in gold-bearing minerals, gold in an adsorbed state, and crystals showing homogeneous and isomorphous substitution. Ge gold or solid solution gold, etc.
The beneficiation method of gold ore should not only be selected based on the physical and chemical properties such as ore type, mineral composition, mineral structure and embedded characteristics as basic conditions, but also should consider the content of valuable components and adaptability to antimony metallurgical technology. requirements and final economic benefits and other factors.
According to surveys, about % of rock gold mines in my country use flotation to prepare gold. In recent years, the product structure has undergone major changes, and most of them are processed on site (of course, due to conflicts between selection and smelting and pricing, etc. (problems, forcing mines to deal with them on site) have led to greater development of flotation technology, which occupies a very important position in gold production. There are usually two processes: preferential flotation and mixed flotation.
In recent years, there have been new developments in process modification and chemical addition systems, and the flotation recovery rate has also been significantly improved. According to the survey results of flotation process indicators in many gold processing plants across the country, the recovery rate of sulfide ore flotation is %, and a few are as high as %~%. The recovery rate of oxide ore is around %~%. The staged grinding and flotation process, combined heavy & flotation process, etc. are the main trends in the development of flotation technology in my country. Of course, flotation, like other methods, is not a panacea and cannot be effective for all gold-bearing ores. The properties of the ore must also be considered. When selecting a process, multiple demonstrations and tests are required.
