Technological Transformation and Practice of Grinding and Floating Process of A Gold Mine Concentrator Plant
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.
