在硫化矿浮选中矿浆的氧化是一个重要因素。黄铁矿尤其磁黄铁矿比例越高,氧化就越重要。既然如此,我们可以通过流程中试样点和试验时间调节氧饱和率。将实验室批量试验所需的氧化时间与半工业厂连续试验所需的氧化时间进行比较,其结果近似。用工业磨矿分级流程中生产的矿浆,其氧化率相当于实验室浮选槽中氧比15分钟的矿浆氧化率。在闪锌矿的浮选中,要获得良好的回收率,必须使氧饱和率保持最小,其氧化时间相当于实验室的90分钟。假如氧化后添加硫酸铜,而硫酸铜起到活化作用,可以使氧化率提高。
Oxidation of pulp in sulfide flotation is an important factor. The higher the proportion of pyrite, pyrrhotite, the more important the oxidation. In this case, we can adjust the oxygen saturation rate through the sample points in the process and the test time. The oxidation time required for laboratory batch tests is compared with the oxidation time required for continuous testing in semi-industrial plants and the results are approximate. Pulp produced in an industrial grinding and classification process has an oxidation rate equivalent to the oxidation rate of slurry in the laboratory flotation tank for 15 minutes of oxygen. In the flotation of sphalerite, to obtain a good recovery rate, the oxygen saturation rate must be kept to a minimum and the oxidation time corresponds to 90 minutes in the laboratory. If added after the oxidation of copper sulfate, and copper sulfate play an active role in the oxidation rate can be increased.
