Measuring ROM at Highland Valley Copper - WipWare

Highland Valley Copper is in an almost unique situation of knowing the amenability of the ore they are treating through systems put in place to measure and monitor the ore properties in real-time. This information can then be used by the mine and mill engineers to improve the productivity and efficiency of their operations.

CuDECO Limited | Processing

The jigging process to recover the coarse (-40, +1mm) native copper nuggets was demonstrated on a continuous pilot alljig®. A decision was made to recover the fine native copper (-1mm) prior to the milling process, to ensure that native copper is not accumulated in the mill. Once the native copper ore has been depleted.

Production Process - Southern Copper Corporation

The concentration process starts here, which consists in a first separation of metal from waste material. 4. MILLING Next, the crushed material is sent to the mills, where rocks are ground into fine powder. This stage of the process uses water in order to release copper and molybdenum particles. 5. FLOTATION After milling.
