Copper oxides are more abundant near the surface, but are considered low-grade ore, with a lower concentration of copper. Although this requires more ore to be extracted and processed, this process is less expensive, so oxides can still be mined at a profit. On the other hand, while copper sulfide ores are less abundant, they contain higher amounts of copper. Although the processing costs are

Generally, crush the copper ores to 0 ~ 5 mm or 0 ~ 9 mm, and then group them by the jigger or shaking table: 1 Separation of lean and rich ores. Some sedimentary primary copper oxide ores are processed by dense media and jigger to remove gangues to obtain massive concentrates because of the depletion of mining. 2 Separation of coarse and fine
