Investigation of Beneficiation for a High Arsenic & Sulfur-containing Gold Ore from Anhui Province

Abstract

Abstract: The detailed mineralogical study about a high arsenic & sulfur-containing gold ore is carried out，and based on this，a magnetic separation-gravity joint test process is proposed.After the conditioning tests of grinding size for magnetic separation，magnetic strength，fineness for gravity separation etc.，the qualified sulfur concentrate with a 17.81% of recovery containing 36.11% of sulfur and 0.03% of arsenic，and gold concentrate with a 47.63% of recovery containing 16.84% of gold and 13.63% of arsenic are obtained.

Key words: Refractory gold ore, Process mineralogy, Gravity concentration
