Study on beneficiation of a low-grade refractory copper oxide ore in Tajikistan

摘要

Experimental investigation was conducted on a low-grade copper ore in Tajikistan with grade of 0.89% and oxidation rate of 99%, which belongs to refractory oxide copper with low-grade and high oxidation rate. According to the property of process mineralogy, using vulcanization xanthate flotation process, determined once rough concentration, three times cubic concentration and three times scavenger concentration process, eventually obtained copper concentrate with grade of 15.26% and recovery rate of 85.90%.
