钙钛矿的分子式为CaTiO_3,在金伯利岩中含量较高,以TiO_2计含2—4%,以钙钛矿计含4—8%以上。以往地质学家认为它无实用价值。其钛、钙成分正是做钙钛型焊条之有益成分。以往焊条涂料—金红石,主要靠进口,为寻找代用品并节省外汇,进行了钙钛矿选收研究,取得了一定效果。(一)原料性质试料来自金刚石重选尾矿。先将尾矿用φ300毫米旋流器脱去+200目沉砂,溢流用φ75毫米旋流器脱-10微米细泥,-74+10微米粒级为试料。试料金属矿物以磁铁矿、黄铁矿和钙钛矿为主;脉石矿物以蛇纹石、绿泥石、角闪石、方解
The formula of perovskite is CaTiO_3, which is high in kimberlite, 2-4% in terms of TiO_2 and 4-8% in terms of perovskite. Geologists in the past think it has no practical value. Its titanium, calcium composition is the beneficial component of calcium-titanium electrode. In the past electrode coating - rutile, mainly by imports, in order to find substitutes and save foreign exchange, the perovskite election study, and achieved some results. (A) the nature of raw materials from the diamond re-election tailings. First tailings with φ300 mm cyclone off +200 mesh grit, overflow with φ75 mm swirling off -10 micron fine mud, -74 +10 micron particle size for the sample. The main metal minerals in the sample are magnetite, pyrite and perovskite. The gangue minerals include serpentine, chlorite, amphibole,
