Because of soluble copper and floatable gangue minerals in the ore, Cu-S bulk flotation technological flowsheet is adopted and obtain good metallurgical performance.
针对该矿石含有水溶铜及大量易浮脉石，采用铜硫混合浮选工艺，获得了较好的选矿指标。
After microcrack treatment, their leaching rate can be notably increased with decrease of the content of freely soluble copper and removal of flotation reagent on mineral surfaces.
这种金精粉经微爆处理后，由于组成矿物的特性发生了一系列的变化，加之脱除了残留在矿粒表面的浮选药剂，金的浸出率可得到大幅度的提高。
