摘要：Deposition of gold ions in the process of agitation with a chloride-hypochlorite solution with 8.15 g/l active chlorine concentration in the model material was studied. Fresh chlorite-hypochlorite solution was used in the study. The effect of the initial pH of the medium on the dynamics of gold deposition is considered. It was found that up to 56% of gold precipitates in alkaline medium. Precipitation is not observed at pH<6. It is established that the ore under investigation has buffer properties and stabilizes the pH of the medium to weak-acid (pH = 5.5-6).
