摘　　要：研究了由蛇纹石或其尾矿制取硅酸镁和超细氢氧化镁的工艺。结果表明,在最佳工艺条件下制取的三硅酸镁、六硅酸镁和氢氧化镁产品的主要技术指标均达到了标准(或药典)要求,氢氧化镁颗粒呈近似球形,为超细粒子。In this paper,the magnesium silicate and ultrafine magnesium hydroxide is prepared by using serpentine or its tails as raw material.One can analyse the composition of original serpentine,acid leaching filter cake and its alkaline leaching residue by XRD and the morphology and particle-size of the magnesium hydroxide by SEM.The results indicated that the product quality of magnesium trisilicate,magnesium hexasilicate and magnesium hydroxide prepared under the optimum technological conditions,can up to the national standards or pharmacopoeia.In addition,the morphology of magnesium hydroxide is nearly spherical.It is the superfine particle.
