本文提出一种基于使用浮选气体（空气、氮等）的方法用于电位控制浮选。以复杂硫化矿物和两种金矿为例．用这种控制方法，在整个浮选阶段电位可在2－5mV之间保持恒定。与不控制电位相比较，在控制电位的条件下从复杂矿浮选铜矿物的选择性显著提高．在低电位下硫化矿物回收率很低的而在由过量充气产生的高电位下选择性也不好。大约0mV（相对于SHE）选择性最大。在金矿浮选中，用电位控制可使铁和砷化矿物例如黄铁矿和砷黄铁矿的回收减至最小。对于金浮选最佳电位是＋250到＋300mV（相对于SHE）。
This paper presents a method based on the use of flotation gas (air, nitrogen, etc.) for potential-controlled flotation. Take complex sulphide minerals and two gold deposits for example. With this control method, the potential can be constant between 2-5 mV throughout the flotation stage. The selectivity to flotation of copper minerals from complex mines at controlled potentials is significantly improved compared to uncontrolled potentials. Sulfur mineral recovery is low at low potentials and not good at high potentials due to overcharging. About 0mV (relative to SHE) the most selective. In gold flotation, potential control minimizes the recovery of iron and arsenic minerals such as pyrite and arsenopyrite. The best potential for gold flotation is +250 to +300 mV (relative to SHE).
