东鞍山铁矿浮选车间,今年以来,采取在浮选精矿脱水过程中扩大浓缩面积、强化过滤设备的维护检修等措施,使浓缩机的溢流浓度由1—2％(最高达7％)降低到0.02—0.04％(一般为0.02％),使浓缩机之精矿流失量由原来150吨/日减少到5吨/日,七月份实际金属回收率达到77.46％,比1963年最高月份提高10.5％,超过了历史上的最高水平,解决了投产以来所形成的“细泥粘”细级别精矿难沉降、难过滤或水份大的问题。
Since the beginning of this year, Dongsanshan iron ore flotation plant has adopted such measures as expanding the condensing area in the process of dehydration of flotation concentrates and strengthening the maintenance and overhaul of filtering equipment so that the overflow concentration of the concentrator will increase from 1-2% (up to 7% ) To 0.02-0.04% (usually 0.02%), reducing concentrator concentrate loss from 150 tons / day to 5 tons / day. Actual metal recovery in July reached 77.46%, up from the highest level in 1963 Increased by 10.5%, surpassing the highest level in history, and solved the problem of difficult settling, difficult filtration or heavy water of fine grade fine clay formed since put into production.
