鑫汇公司350 t/d选矿厂工艺优化改造

摘要

基于对低能耗及设备高效利用的要求,鑫汇公司350 t/d选矿厂原工艺流程已无法满足现场的生产需求,对其进行了工艺优化改造.通过调整破碎机安装位置、振动筛安装方向、药剂制度以及更换细碎设备、筛网尺寸等措施,达到了节能降耗的目的,不仅增加了选矿厂的生产能力,而且提高了金的回收率,由89.08%提高到92.58%,年增创收益达1494.41万元,经济效益和社会效益显著.%In terms of the requirement of low energy consumption and efficient use of equipment , the previous process flowsheet operated in the 350 t/d mill of Xinhui company is no longer able to meet the demand of production . So process optimization is conducted .The measures,including adjustment of installation place of the crusher ,installa-tion direction of the vibration screen ,agent regime ,and the update of finely grinding equipment and screen mesh size , reaches the goal of low energy consumption and high efficiency .The production capacity is improved for the dressing plant and the gold recovery rate is increased from 89.08%to 92.58%,with annual profits of 1.49441 million yuan. The economic and social benefits are evident .
