The Experimental Research On the Separation of Sulur and Arsenic in a Sulphur-gold Ore

The sample was from the tailings of gold's flotation of a sulfur-gold mine. Using the technology flowsheet of magnetic separation -priority floating sulfur and removing arsenic, by the test of small closed circuit in the lab, the results were obtained that the sulfur grade of magnetic concentrate is 39.32% with 27.97% of recovery, the sulfur grade of pyrite concentrate is 49.78% with of 43.97% of recovery, and the arsenic -gold concentrate contained 18.42% of arsenic with 89.47% of recovery, 12g / t of gold with 68.72% of recovery.
