摘要：

The reaction of mechanically activated galena with ferric chloride solution was investigated in the concentration range [Fe3+] = 0.01-0.6 M at temperatures between 303 and 338 K. The mechanical activation lasting 5-30 min was carried out in a planetary mill. It has been found that this reaction is sensitive to the microstrains produced in the structure of galena during grinding as well as to the concentration of Fe3+ in the solution. The influence of Fe3+ concentration is in operation practically only in the region [Fe3+] < 0.2 M.
