摘　　要：试验证明了利用高硅氧化锌矿酸浸过程中所产生的可溶硅酸与硫酸镁反应生成硅酸镁沉淀的可能性。对影响脱镁反应参数的考察表明 ,镁的脱除率与可溶硅酸浓度及温度的高低密切相关 ,以其浓度表示则需大于 1 0g/LSiO2 ,脱镁温度 65℃左右为宜。Experimental results have confirmed the possibility of obtaining magnesium silicate by utilizing the soluble silicic acid,generated during the acid leaching of zinc oxide ore bearing high content of silicon,reacting with magnesium sulfate.The study on factors affecting the removal of magnesium indicated that the removal of magnesium was greatly influenced by the concentration of silicic acid and temperature.It has been explored that the condition with SiO 2 concentration of 10g/L and temperature of 65℃ is preferable.
