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.
