摘要： A method of manufacturing zinc carbonate for animal feed by reacting waste containing zinc ash and an ammonium bicarbonate solution and then heating is provided to recover zinc carbonate from waste at low cost. Waste containing zinc oxide such as zinc ash is reacted with an ammonium bicarbonate solution to give a zinc ammonium carbonate complex which is heated at 90 to 95deg.C to give zinc carbonate. For an example, 10kg zinc ash with a zinc oxide content of 80% and 8kg ammonium carbonate are poured into 30L water, agitated at 50deg.C for 3hr, added with 30g zinc powder, agitated for 30min and filtered. The filtrate is added with 100g potassium permanganate to precipitate iron and filtered. The filtrate is heated at 90 to 95deg.C, sprayed with a zinc ammonium carbonate solution to eliminate ammonium of zinc ammonium carbonate. The generated ammonia and carbon dioxide are poured to recover 7.8kg zinc ammonium carbonate complex which is heated to give 11.5kg zinc carbonate with a purity of 99.5%.
摘要翻译：提供了通过使含有锌灰和碳酸氢铵溶液的废物反应然后加热来制造用于动物饲料的碳酸锌的方法，以低成本从废物中回收碳酸锌。将含有锌灰的氧化锌的废物与碳酸氢铵溶液反应，得到碳酸锌铵络合物，将其加热至90〜95℃，得到碳酸锌。例如，将10kg氧化锌含量为80％的锌灰和8kg碳酸铵倒入30L水中，在50℃下搅拌3小时，加入30g锌粉，搅拌30分钟并过滤。滤液中加入100g高锰酸钾沉淀铁并过滤。将滤液加热至90〜95℃，用碳酸锌铵溶液喷雾以除去碳酸铵铵的铵。将所生成的氨和二氧化碳倒入以回收7.8kg碳酸锌铵络合物，将其加热得到11.5kg纯度为99.5％的碳酸锌。
