摘　　要：“天然碱”是指由自然界地质作用形成的各种含碳酸钠、碳酸氢钠的可溶性盐类矿物。天然碱矿采出后经工厂加工,主要产品是碳酸钠(纯碱)和碳酸氢钠(小苏打)。目前国内外主流的天然碱加工方法有蒸发法和碳化法,其中,蒸发法还可以依据原料组成不同进一步细分为一水碱工艺和倍半碱工艺。经统计,天然碱加工工艺的占比如下:一水碱工艺占比66.4%,倍半碱工艺占比21.2%,碳化工艺占比12.4%,一水碱工艺是目前国内外主流的天然碱加工工艺。“Natural alkali”refers to various soluble salt minerals containing sodium carbon-ate and sodium bicarbonate formed by the geological action of nature,and the main products are so-dium carbonate(soda ash)and sodium bicarbonate(baking soda)after natural alkali ore is ex-tracted and processed by the factory.At present,the mainstream natural alkali processing methods at home and abroad are evaporation method and carbonization method,among which evaporation method can be further subdivided into monohydrate alkali process and sesqui-alkali process accord-ing to the different composition of raw materials.After statistics,the proportion of natural alkali technology:66.4%for monohydrate process,21.2%for sesqui-alkali process,12.4%for carbon-ization process,monohydrate process is the mainstream natural alkali processing process at home and abroad.
