These compounds are soluble in water, and contains the hemiacetal hydroxyl free, so in alkaline solution can reduce silver ions and copper ions.
这些化合物能溶于水，并含有游离的半缩醛羟基，所以在碱溶液中能还原银离子和铜离子。

Because of solublecopper 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 solublecopper and removal of flotation reagent on mineral surfaces.
