摘要:河北省A金矿选矿厂针对选矿工艺及环保问题,为了稳定生产、充分挖掘生产技术指标提升潜力,提高
选矿厂的日处理能力和金回收率,开展了技术改造及选矿工艺应用研究。通过改变选矿工艺,将现有炭浆法提金
工艺改为浮选工艺,并通过调节作业制度、优化工艺流程、更换相关设备等方式,将选矿厂生产能力由350 t/d
扩大至450 t/d,稳产年年均处理量达到1.485 ×105 t,选矿回收率由68%提高到了89%,项目达产年年均销售收
入3.806 4 ×107元,年均净利润4.182 ×106元。经过技术改造后,选矿厂以合理的投入获得最大的经济效益和社
会效益。

Abstract: In view of the mineral processing technology and environmental protection problems, A Gold Mine Concentration
Plant in Hebei Province carried out technical transformation and mineral processing process application research in order
to stabilize production, fully tap the potential of production technical index improvement, and improve the daily processing
capacity and gold recovery rate of the concentrator plant. By changing the beneficiation process, the existing carbon slurry
gold extraction process was changed to a flotation process, and the production capacity of the concentrator plant was
expanded from 350 t/d to 450 t/d by adjusting the operation system, optimizing the process flow, replacing related
equipment, etc., the average annual processing capacity of stable production reached 1.485 ×105 t, the mine processing
recovery rate increased from 68% to 89%, and the average annual sales revenue of the project reached 3.806 4 ×107 yuan
and the average annual net profit was 4.182 ×106 yuan. After technical transformation, the concentrator plant obtains the
maximum economic and social benefits with reasonable input.
