  METHOD OF PRECIPITATION OF METAL IONS

  摘要：

  本发明涉及一种金属离子沉淀的方法。采用镁和/或钙的矿物、氧化物、羟基物作为原材料，并通过至少一步煅烧、消石灰或碳化的处理将原材料处理成镁重碳酸盐和/或钙重碳酸盐的水溶液，然后将该溶液用作沉淀剂，沉淀稀土，如镍、钴、铁、铝、镓、铟、锰、镉、锆、铪、锶、钡、铜和锌离子。获得至少一种金属碳酸盐、羟化物或碱式碳酸盐，或者进一步将获得的产品煅烧以产生金属氧化物。本发明采用价格便宜、纯度低的钙和/或镁矿物或其氧化物、羟基物代替常见的沉淀剂，如碳酸铵和碳酸钠等。钙、镁、二氧化碳等被高效循环利用，避免了铵氮废水、高浓度盐类废水对环境的污染，减少了温室气体二氧化碳的排放和金属生产成本。

  The present invention relates to a method of precipitation of metal ions. Mineral(s), oxide(s), hydroxide(s) of magnesium and/or calcium are adopted as raw materials, and the raw material(s) is processed through at least one step of calcination, slaking, or carbonization to produce aqueous solution(s) of magnesium bicarbonate and/or calcium bicarbonate, and then the solution(s) is used as precipitant(s) to deposit rare earth, such as nickel, cobalt, iron, aluminum, gallium, indium, manganese, cadmium, zirconium, hafnium, strontium, barium, copper and zinc ions. And at least one of metal carbonates, hydroxides or basic carbonates is obtained, or furthermore the obtained products are calcined to produce metal oxides. The invention takes the cheap calcium and/or magnesium minerals or their oxides, hydroxides with low purity as raw materials to instead common precipitants such as ammonium bicarbonate and sodium carbonate etc. The calcium, magnesium, carbon dioxide etc are efficiently and circularly used, and the environment pollution by ammonium-nitrogen wastewater, high concentration salts wastewater is avoided, and both of the discharge of greenhouse gas carbon dioxide and the production cost of metal are decreased.
