Abstract

The hydrometallurgical processing of industrial converter mattes with the copper-to-nickel concentration ratios (Ni : Cu) of 2 : 1 and 3 : 4 is studied in order to demonstrate the advantages of hydrometallurgical processing methods, which can improve the environment and increase the number of important components extracted from raw materials. The results obtained indicate the possibility of direct leaching of the converter mattes with different copper and nickel contents under atmospheric conditions. During leaching, the extraction of to 94–95% nickel into a solution takes place; the solution is subjected to electroextraction; and the solid residue (copper cake) contains to 95% copper of its initial content in the converter matte. A high copper content in the converter matte is found to decrease the extraction of nickel into the solution.

铜镍转化器雾面湿法冶金加工的可能性的证实

摘要

为了证明湿法冶金加工方法的优点，可以改善环境并增加环境污染，对铜/镍浓度比（Ni：Cu）为2：1和3：4的工业转炉磨砂进行了湿法冶金处理。从原材料中提取的重要成分的数量。获得的结果表明，在大气条件下，具有不同铜和镍含量的转炉粗砂有可能直接浸出。在浸出过程中，将镍萃取至溶液中的94-95％。溶液进行电萃取；固态残渣（铜饼）在转炉毛面中的初始含量为95％。发现转炉磨砂中的高铜含量会减少镍向溶液中的萃取。
