摘要：
A process for alumina and carbonate production from aluminium rich materials with integrated CO2 utilization, comprising: comminuting and leaching Al-rich materials in concentrated HCI; separating unreacted material from metal chloride solution; separating Al3+ from solution by crystallization of AlCl3.6H2O; calcination of AlCl3.6H2O with HCl recovery; precipitation of metal carbonates from CO2; regeneration of HCl and extractive amines; the Al3+ separation the facilitated by increasing HCl concentration; the calcination being performed in two steps, one in the range 400 and 600° C. to generate a HCl-rich gas and one above 600° C. to produce Al2O3; for precipitating metal carbonates, mixing the metal chloride solution with an organic solution containing a selected amine and contacting the mixture with a CO2-containing gas, thereby also extracting HCl by formation of an ammonium chloride salt complex; processing thermally or chemically the organic solution to regenerate the amine for recirculation.
摘要（中）：
一种用于氧化铝和碳酸酯的制造从富铝材料具有集成CO2利用率，方法包括：粉碎和在浓HCl浸出富Al的材料; 分离金属氯化物溶液的未反应的材料; 从由AlCl3.6H2O的结晶溶液中分离的Al 3+; AlCl3.6H2O用HCl恢复的煅烧; 从CO2金属碳酸盐沉淀; HCl和采掘cardamines的再生; 所述Al 3+分离由增加的HCl浓度提供便利; 煅烧正在执行在两个步骤，一个在范围400和600℃下，以产生富含HCl气体和一种以上600℃以产生氧化铝; 用于沉淀金属的碳酸盐，在有机溶液中的金属氯化物溶液与混合含有选择的胺，并用含CO 2的气体接触的混合物，所以由此通过形成氯化铵盐络合物中提取盐酸; 热加工或化学的有机溶液以再生胺用于再循环。
