金川有色金属公司的二矿区矿石储量最大,矿石可选性好。为开发和提高二矿区富矿石选矿指标,不少单位共同进行大量的酸法、碱法和中性介质的选别工艺流程试验。经技术经济比较,确定中性介质的选矿流程作为一期工程二矿区富矿选矿流程,并作为二选厂扩建和改造的设计依据。鉴于二矿区已形成一定生产能力,1983年生产计划和二选厂实际情况,参照中性介质的连选试验流程,在二号系统磨浮流程的基础上,进行了改
Jinchuan Nonferrous Metals Company’s ore reserves of the two ore maximum, good ore selectivity. In order to develop and improve the beneficiation index of ore ores in No.2 mining area, many units jointly conduct a large number of sorting process tests on acid, alkali and neutral media. After technical and economic comparison, determine the beneficiation process of neutral medium as the second stage ore beneficiation process, and as a second choice of plant expansion and transformation of the design basis. In view of the second mining area has formed a certain production capacity, 1983 production plan and the actual situation of the second plant, with reference to the neutral medium of the election process, based on the No. 2 system grinding process on the basis of change
