This invention belongs to the field of mineral processing technology, specifically relating to a selective sulfidation roasting-flotation separation method for a smithsonite-calcite mixed ore. The method first involves crushing and grinding the smithsonite, calcite, and sulfiding agent, then mixing them in a certain proportion and subjecting them to sulfidation roasting, preferentially causing the smithsonite to undergo sulfidation. After cooling the roasted product in an inert atmosphere, flotation separation is performed using xanthate as a collector to obtain zinc concentrate. By controlling the atmospheric conditions during the sulfidation roasting process, the sulfidation reaction efficiency of the smithsonite can be improved, and the generation of sulfur oxide gases during roasting can be reduced. When using this method to process the smithsonite-calcite mixed ore, effective recovery of the smithsonite can be achieved, with a flotation recovery rate exceeding 88%. This invention features a simple process flow and easily controllable operating conditions, providing a new technical approach for the efficient utilization of smithsonite resources.

The invention discloses a low-grade zinc oxide ore amine sulfide process defoaming agent and application thereof.The low-grade zinc oxide ore amine sulfide process defoaming agent is characterized in that firstly, ore is crushed and ground to achieve monomer dissociation between minerals, and meanwhile, a small amount of sodium carbonate and sodium sulfide are added into a grinding machine to serve as regulators; lS-X1 is used as a selective defoaming agent for amine sulfide flotation of smithsonite, and zinc sulfide concentrate is obtained after a section of roughing operation; and sodium sulfide and sodium carbonate are added into the zinc sulfide tailings for activation, and zinc oxide concentrate and tailings are obtained after the one-roughing, one-refining and one-scavenging flotation process. The efficient flotation defoaming agent LS-X1 has high selective defoaming capacity, has high defoaming capacity on amine collecting agents, does not affect the flotation performance of the amine collecting agents, and can greatly reduce the foam stability of the amine collecting agents, so that flotation closed cycle can be carried out; the method has the advantages of high feasibility, wide application range, high product index and the like.

The invention discloses purple sand pug rich in trace elements. The purple sand pug comprises the following components in percentage by weight: 6%-8% of selenium silver ore, 8%-12% of strontianite, 25%-30% of spodumene, 3%-6% of smithsonite and 44%-58% of purple sand raw ore pug. The finished product is obtained by mixing the purple sand pug and the mineral aggregate rich in trace elements in the firing process, and trace elements are separated out after the purple sand pug and the mineral aggregate are soaked in water. The invention provides the purple sand pug rich in trace elements, which is high in yield and convenient to form after being fired, and the trace elements are separated out after being soaked in water, and the preparation method thereof.
