我国磷矿资源丰富,全国各地均有不同规模的钙镁磷肥厂,在磷肥的生产工艺中,产出一定数量的镍磷铁合金,该合金进行电解以回收金属镍,副产为阳极泥,除含有镍铜等有价金属外,还有相当数量的金、铂、钯、钌等贵金属,其总含量一般为100~150克/吨.无疑,这是贵金属生产的一个重要原料,若将全国大中小磷肥厂的镍磷铁合金或
China is rich in phosphate rock resources. There are different sizes of calcium magnesium phosphate fertilizer plants all over the country. In the production process of phosphate fertilizer, a certain amount of Ni-P ferroalloy is produced. The alloy is electrolyzed to recover nickel metal and the by-product is anode mud. Containing nickel and copper and other valuable metals, there are a considerable amount of gold, platinum, palladium, ruthenium and other precious metals, the total content is generally 100 ~ 150 g / t .Undoubtedly, this is an important raw material for precious metals production, if the national Medium and small phosphate fertilizer plant nickel-iron-phosphorus alloy
