磐石镍矿是个采选冶联合企业,目前只生产高冰镍。1980年1500吨/日选矿厂扩建工程投产时,矿领导在北京有色冶金设计研究总院配合下,狠抓了提高选矿精矿品位的工作,使之由扩建前(设计的)4％提高到6％以上,精矿量减少了34％。由于挖了提高精矿品位的潜力,冶炼电炉能力相应提高0.5倍,高冰镍成本降低30％,节省能源40～45％,从而达到 Rock nickel ore mining and metallurgy is a joint venture, currently only producing high-nickel ice. When the 1,500 tonne / day processing plant expansion project was put into operation in 1980, with the cooperation of Beijing Nonferrous Metallurgical Design and Research Institute, the mine leaders paid close attention to the work of upgrading concentrate concentrates to 4% of the pre-expansion (designed) level More than 6%, the amount of concentrate decreased by 34%. As a result of digging up the potential of improving concentrate grade, the capacity of smelting electric furnace is correspondingly increased by 0.5 times, the cost of high-ice nickel is reduced by 30% and the energy saving by 40 ~ 45%, so as to achieve
