Production technology of high-grade sulfur concentrate

The invention belongs to the field of beneficiation, and particularly relates to a production technology of high-grade sulfur concentrate. The technology comprises the steps of conducting preliminaryroughing, concentration and enrichment, tailings scavenging and recycling and the like on zinc tailings. The sulfur-containing grade of the sulfur concentrate is improved, the recycling rate of the sulfur concentrate is increased, the technology process is simple, the production cost is low, and thus the production technology is suitable for industrial application and popularization. 本发明属于选矿领域，具体涉及一种高品位硫精矿的生产工艺，该工艺将锌尾矿通过初步粗选、精选富集、尾矿扫选回收等过程，提高了硫精矿的含硫品味并提高了硫精矿的回收率，工艺流程简单，生产成本较低，适用于工业推广应用。
