一种机械化学强化黄铜矿浸出的方法
摘要：
本发明公开了一种机械化学强化黄铜矿浸出的方法，将黄铜矿与氧化剂按质量比0～7:1进行混合，经行星式球磨机机械活化处理0.25～3h后，黄铜矿和氧化剂发生固相反应形成新的化合物，再经pH为1～7溶液在40～85℃下进行浸出，浸出时铜以铜离子的形式进入溶液中。与传统酸浸方法相比，本发明具有更快的浸出速率，且铜浸出率高达98％，因此具有广大的应用前景。
摘要（英）：

The invention discloses a method for strengthening chalcopyrite leaching through the mechanochemistry. The method includes the steps that chalcopyrite and an oxidizing agent are mixed according to themass ratio of 0-7:1; after a planetary ball mill conducts mechanical activating treatment for 0.25-3h, the chalcopyrite and the oxidizing agent carry out a solid-phase reaction to form a new compound; and then leaching is performed at the temperature of 40-85 DEG C through a solution with the pH being 1-7, and copper enters the solution in the form of copper ions in the leaching process. Comparedwith a traditional acid leaching method, the method for strengthening chalcopyrite leaching through the mechanochemistry is higher in leaching rate, the copper leaching rate reaches high to 98%, andthus the application prospects are wide.
