近十五年来,由于高压湿法冶金技术的迅速发展,氨浸法得到了广泛地探索和应用,它不仅在銅、鎳、鈷有色金属方面已付諸工业实践,同时在鈾、錳、鋅等矿石处理方面也引起了注意;它不仅在处理精矿及毓方面有許多长处,而且在直接处理低品位矿石,特別是难选性氧化矿方面也有許多无可比拟的优点。在氨法处理金属矿物的流程中,自氨性溶液中如何有效而經济地回收金属,乃是一个重要的部分。在
In recent fifteen years, due to the rapid development of high pressure hydrometallurgy, ammonia leaching has been widely explored and applied. It has not only been put into practice in the fields of copper, nickel and cobalt nonferrous metals, but also has been applied in uranium, manganese and zinc Ore processing has also drawn attention; it has many advantages not only in concentrates and concentrates, but also in its direct handling of low-grade ores, especially refractory oxides. How to recover metals efficiently and economically from ammoniacal solutions is an important part of the process for treating metallic minerals with ammonia. in
