苏联利萨科夫采选公司重磁选流程选矿厂于1972年投产,所处理的矿石为鲕状褐铁矿石。矿石中的主要金属矿物为水针铁矿、针铁矿、铁绿泥石;非金属矿物为石英及少量粘土物质、碳酸盐、长石、玉髓、绢云母等。水针铁矿鲕粒的尺寸为0.05～0.6mm;石英颗粒的尺寸为0.1～1.0mm。选矿厂现有的工艺规定,矿石经破碎和磨碎后,其粒度达到1.6mm 以下,再经重选、磁选得到的精矿,含铁约49%,尾矿含铁26～27%。根据采用的流程,磨矿后的矿石、跳汰的中矿和精矿,都要在 KCH-24及 Soviet Lisakov mining company gravity magnetic separation process put into operation in 1972, the ore processing for the oolitic brown iron ore. The main metal minerals in ore are goethite, goethite and iron chlorite; the non-metallic minerals are quartz and a few clays, carbonates, feldspar, chalcedony, sericite and the like. The size of the oozeite gypsum is 0.05-0.6 mm; the size of the quartz grit is 0.1-1.0 mm. Concentrator existing process requirements, the ore after crushing and grinding, the particle size of 1.6mm or less, and then by re-election, the concentrate obtained by magnetic separation, about 49% of iron, iron tailings 26% to 27%. According to the adopted process, the ore after grinding, jig and concentrate in the jig, should be KCH-24 and
