Bavarder sur Internet2021.11.30 Electrowinning is the electrolytic process of “winning” or recovering dissolved metal using an applied potential. An example of an electrowon copper plate is shown in Fig. 7.1. This process is practiced extensively in the metals industry. Copper, zinc, and gold, as well as other metals are produced by this process.

Bavarder sur Internet2023.7.28 The use of thiosulfate to extract gold from refractory ores is promising because of its non-toxicity and high selectivity. Sulfide minerals (i.e., pyrite, arsenopyrite, chalcopyrite), major gold carriers in refractory gold ores, however, hinder gold extraction due to the high consumption of a lixiviant. In this study, a new method to improve gold
