铜官山选矿厂是一个以铜为主的铜、硫、铁多金属选矿厂。磁选车间为选矿厂的一个辅助车间,主要承担从铜尾矿中回收硫、铁的任务。投产初期选铁原流程为先磁(选铁)后浮(选硫)流程,铁精矿含硫高,不能保证产品质量。在毛主席革命路线指引下,在我厂广大工人、技术人员和干部的共同努力下,先后经过1964年和1970年两次技术改造,选铁流程改造成先浮后磁,硫尾矿选铁,磁性矿反浮选脱硫。从而基本上解决了铁精矿产品质量,同时回收了大量的铁精矿和硫精矿,在综合利用的大道上迈出了可喜的一步。 Tongguan Mountain concentrator is a copper-based copper, sulfur, iron and more metal concentrator. Magnetic separation plant for the dressing plant an auxiliary workshop, mainly responsible for the recovery of sulfur from the copper tailings, iron task. Initial iron ore production process for the election of the first magnetic (election iron) after the float (sulfur) process, high iron ore concentrate, can not guarantee product quality. Under the guidance of Chairman Mao's revolutionary line and with the joint efforts of the vast majority of workers, technicians and cadres in our factory, we have successively transformed our iron selection process into the first float-back magnetic and sulfur-tailing iron-smelting works through two technological reforms in 1964 and 1970, Magnetic anti-flotation desulfurization. Which basically solved the quality of iron concentrate products, while recovering a large number of iron concentrates and concentrate, in the comprehensive utilization of the road has taken a gratifying step.
