摘要
对临桂县白云石矿石的化学成分和物相进行了分析，得出临桂县白云石中MgO的平均含量为21．1％，接近白云石的理论组成。属于晶质的白云石类型，单晶体常呈菱面体，集合体常呈粗粒至细粒状，结构致密。经过适当温度（750—800℃）煅烧后，所得苛性白云石的活性氧化镁含量可达到27％左右，是生产苛性自云石的较好原料。
The chemical composition and mineral phase of the dolomite ore from Lingui county area in Guangxi province have been analyzed. The average content of MgO in the dolomite was 21.1%, which approaches the theoretical composition of the dolomite. The dolomite is crystalline. Its monocrystal presents rhombohedron surface. Its mass is composed of the thick grains to small particles and the texture is compact. The dolomite can be calcined as the magnesia cementitious material which contains the active magnesia of 27% or so under the temperature condition from 750% to 800℃. The dolomite is a better raw ore to produce the caustic dolomite.
