湖南青山硫铁矿老厂为手选厂,1988年10月建成新选厂为机选厂,两厂年处理原矿10万吨。为扩大生产能力至15万吨,矿山委托湖南化工研究院对该厂进行技术改造。 一、选厂生产概况 手选厂处理井下含硫23～25％原矿,流程包括碎矿→分级→选矿→筛上手选→产品破碎。选矿结果如图所示。 Hunan Qingshan Pyrite Plant for the hand-selected plant, in 1988 October to build a new plant for the election machine plant, two plants in the processing of 100,000 tons of ore. In order to expand production capacity to 150,000 tons, the mine commissioned Hunan Chemical Research Institute to carry out technological transformation of the plant. First, the selection of plant production Hand-selected factory processing underground sulfur 23 ~ 25% of the ore, the process includes crushing → classification → dressing → screen on hand → product crushing. Beneficiation results as shown.
