Abstract:This article introduces the importance of sulfur concentrates further concentration, and comments on the use of high-quality sulfur concentrates as an important way to increase the overall interest rate and environmental protection level of mineral resources. The technical difficulties and importance in further concentration of sulfur concentrate were analyzed. The progress of flotation, magnetic separation, chemical beneficiation and combined processes for the comprehensive recovery of useful components and the reduction of arsenic content and gangue mineral content in the further concentration of sulphur concentrates are reviewed. It is pointed out that flotation is the most effective technology for upgrading of sulphur oncentrates. The research focus of arsenic-containing sulfur concentrates for arsenic reduction is focused on the use of new depressants of arsenic mineral. Combined processes can make sulfur concentrates more economical, environmentally friendly, and simple to implement. Some refractory sulphur concentrates may require the use of a combined process.
