某铜钼选矿厂低碱介质浮选工业试验研究OA

A copper-molybdenum beneficiation plant has introduced a new sulfur inhibitor BK506 to conduct industrial experimental re-search on low alkali medium flotation in order to solve the problems of low production indicators in the current high alkali flotation process.The research results indicate that,while maintaining the process structure and other reagents unchanged,BK506 can partially replace lime to suppress pyrite,which not only reduces the pH value of flotation operations but also improves production indicators.On site low alkali medium flotation industrial experiment can obtain copper molybdenum mixed concentrate with a copper grade of 25.63%and a copper recovery of 88.57%,molybdenum grade of 1.669%and a molybdenum recovery of 76.67%,with good flotation indica-tors.The industrial experiment of low alkali medium flotation on site can obtain a copper molybdenum mixed concentrate with a copper grade of 25.63%,a copper recovery of 88.57%,a molybdenum grade of 1.669%,and a molybdenum recovery of 76.67%.Compared with the cumulative data of the high-alkali flotation process in the month prior to the industrial experiment,the copper recovery rate in-creased by 3.20 percentage points,indicating favorable flotation indicators.
