| Abstract: | Flotation tests were carried out to treat a low-grade refractory copper oxide ore in Yunnan Province by adopting sulphidizing flotation method with two stages of roughing, one stage of scavenging and four stages of cleaning, at a grinding fineness of -0.075 mm 74.90%, which resulted in 70.33% Cu recovery to copper concentrate grading 21.48% Cu with a yield of 1.11%. |
