Abstract
The invention relates to a lead-antimony-zinc sulfide ore bulk flotation collecting agent and preparation and application thereof. The gearbox left box body shell is prepared by mixing tert-dodecyl mercaptan and emulsified kerosene. The mass ratio of the tert-dodecyl mercaptan to the emulsified kerosene is 1:(0.9-1.2). The lead-antimony-zinc sulfide ore bulk flotation collecting agent has the better collecting effect on sulfide, and can be applied to lead-antimony-zinc sulfide ore bulk flotation. The lead-antimony-zinc sulfide ore bulk flotation collecting agent has the good foaming property, can adopt a small amount or no foaming agent, and can decrease the consumption of an activating agent copper sulfate; compared with traditional MA or single use of emulsified kerosene and tert-dodecyl mercaptan, the grade and recycling rate of sulfide can be increased, and types and consumption of medicament are reduced.
