【摘要】 本文报道了以本省天然矿石粉碎而得的矿粉为原料，直接用酸分解制取氯化锌的实验过程，经硫酸除铅、钙、钡盐除多余的ＳＯ_４^２－，再经氢氟酸除镁并深度除钙后，制得质量指标完全达到国家标准的氯化锌．该工艺能充分利用我省资源，耗能少，产品质量可靠更多还原

【Abstract】 This paper reports the experimenfal process of preparing zinc chloride by means of direct aciclolysis from pulverized raw oves of our province.The product whose quality is well up to the National Standard has been prepared after the processes of first excluding lead, calcium, barium and superfluous SO by sulphuric acid and then excluding magnesium ornd the rencaining calcium by hydroflccoric acid. By using this technological method, full use can be made of the natural resources of our province and the consumption of energy can be cut down. Moreover the quality of the product is reliable.更多还原
