Abstract

The low-grade associated gold in copper ore is often overlooked to recover，due to its difficult to enrich to valuation grade.According to the low gold high-sulfur copper ore，which contains 1.84% of Cu，11.09% of S，and 0.12×10^-6 of Au，P10 is taken as collector for copper and gold，sulfuric acid as activator and butylxanthate as collector for sulfur.A closed-circuit flotation test was conducted at a low alkalinity，which a copper concentrate are produced with content of 20.98% Cu with a recovery of 86.23% and 1.2×10^-6 Au with a recovery of 74.80%， and sulfur concentrate of 48.9% S with a recovery of 74.47%.Therefore，a comprehensive and efficient recovery of copper，sulfur and gold can be realized.Low alkali separation technology of copper-sulfur，which greatly reduced the amount of activator，is conducive to comprehensive recovery of sulfur and lower processing costs.

Key words： high-sulfur copper ore; low-grade associated gold; P10 collector; copper-sulfur separation at low alkalinity
