马钢姑山选矿厂原设计的选别流程是跳汰-磁选-浮选联合流程。即跳汰获得合格粗粒精矿和丢弃尾矿,阶段磨矿阶段选别跳汰中矿,一次磨矿产品用强磁选丢尾矿,二段磨矿产品由浮选获得合格细粒精矿。其生产指标远远低于设计指标。1978年以来,采用螺旋选矿机取代强磁选选别跳汰中矿粗磨产品,获得较好指标。姑山铁矿床系中温热液交代矿床。铁矿物以赤铁矿为主,有少量假象赤铁矿、磁铁矿。脉石矿物主要是石英,次为高岭石、玉髓、蛋白石等。矿石
Magang Gushan ore dressing plant selection process is the original jig - magnetic separation - flotation joint process. Jig access to qualified coarse ore concentrate and discard tailings, stage grinding stage jig selection jig, a grinding product with strong magnetic separation lost tailings, two paragraphs of grinding products obtained by flotation qualified fine granules mine. Its production index is far below the design targets. Since 1978, the use of spiral concentrator instead of strong magnetic separation jigging jig products, get better indicators. Gushan iron ore bed in the hydrothermal fluid replacement deposit. Iron ore mainly hematite, a small amount of illusion hematite, magnetite. Gangue minerals are mainly quartz, followed by kaolinite, chalcedony, opal and so on. ore
