双增双节是提高企业经济效益的重要途径之一。1987年2—4月,我矿针对锡选矿厂回收率多年来徘徊不前的状况,组织21人的技术攻关组,以提高锡回收率为我矿双增双节的主攻方向。采取以下六项技术管理措施,取得了可喜的成绩。(一)进行磨矿试验,寻找最佳磨矿细度磨矿细度是提高选矿回收率的一个关键因素。我矿井下层状锡矿体和管状锡矿体有用矿物嵌布粒度不同,而磨矿细度一直固定在50%-200目。为此,我们进行磨矿试验,实践表明,层状锡矿石和管状锡矿石的最佳磨矿细度分别为55%和45%-200目。(二)用科学方法监督生产长期以来,浮选部分的药剂用量凭经验目测控制,这势必影响选矿指标。因此,我们改用波密计控制药剂用量,用机
Double increase by double is one of the important ways to improve the economic efficiency of enterprises. From February to April 1987, I ore mined the technical recovery group of 21 people in response to the recovery rate of tin beneficiation plant over the years, in order to improve the recovery rate of tin as the main direction of double-double-double-section mine. Take the following six technical management measures, has made gratifying achievements. (A) grinding test to find the best grinding fineness grinding fineness is to improve the beneficiation recovery rate of a key factor. Mine mine tin ore layer and tubular tin ore beneficiation buried minerals of different sizes, and grinding fineness has been fixed at 50% -200 mesh. For this reason, we conducted grinding tests, the practice shows that the optimum grinding fineness of layered tin ore and tubular tin ore are 55% and 45% -200 mesh respectively. (B) the use of scientific methods to monitor production For a long time, flotation part of the amount of pharmaceutical control by empirical inspection, which is bound to affect the dressing indicators. Therefore, we use the Bomi meter to control the amount of pharmaceutical use machine
