Abstract

The present disclosure discloses a combined collector for zinc oxide ore flotation, including the following components in percentage by mass: 60-95 wt % of a fatty acid, 0-10 wt % of a hydroxamic acid and 5-35 wt % of a mercaptobenzothiazole. In the flotation process of zinc oxide ore, due to the use of the combined collector of the present disclosure, it is not required to deslime. On the premise of ensuring the zinc grade in the zinc concentrate, the flotation recovery rate of the zinc concentrate is improved and the zinc grade of mineral processing tailings is reduced by using the combined collector, thereby reducing the loss of zinc metal.
