李家湾铜矿本着综合利用尾矿的指导思想,根据其选铜尾矿的化学成分和目前建材水泥行业掺合料不足,品种单一的情况,进行将尾砂作为水泥掺合料的试验,取得了较好的效果。(一)原矿性质李家湾铜矿矿床属中-高温热液接触矽卡岩型矿床。主要有用矿物为黄铜矿、斑铜矿;主要脉石矿物为硅灰石、钙铁石榴石、方解石和石英等。选铜尾矿及各种原料(分别磨至+0.08毫米占3.8—7%)的化学成分、熟料参数见
Lijiawan Copper Mine in line with the guiding ideology of comprehensive utilization of tailings, copper tailings according to their chemical composition and the current lack of admixture in building materials and cement industry, a single species, the trial of tailings as a cement admixture , Achieved good results. (I) Ore properties The Lijiawan copper deposit is a medium-high temperature hydrothermal contact skarn deposit. The main useful minerals are chalcopyrite and bornite; the main gangue minerals are wollastonite, calcium iron garnet, calcite and quartz. Selected copper tailings and various raw materials (respectively, to +0.08 mm accounted for 3.8-7%) of the chemical composition, clinker parameters see
