Abstract

Y89\|0 xanthate and isobutyl xanthate were used separately as collector to process the refractory earthy CuO ore in Tonglushan Mine. The test results show that, the dose of Y89\|0 is 30%～40% less than that of isobutyl xanthate, provided the similar separation indexes; in a copper sulphide and cupric oxide bulk flotation flowsheet, with the same dose, Y89\|0 can result in a copper concentrate containing Cu 2\^18% higher, Au 6\^5 g/t higher, the recovery of Cu 1\^37% higher and the recovery of Au 9\^32% higher than those by isobutyl xanthate.
