optical sorting of minerals and ore

Performance evaluation of optical sorting in mineral

10-12-2017· Optical sorting is increasingly playing an important role in mineral processing since they have the capability to remove a huge amount of barren particles before crushing and grinding. To this end, more work needs to be done with optical sorters and their response to meet the requirements that are important for the mining industry in terms of capacity, efficiency, and performance.

This means a wide range of mineral types can be separated using an ore sorting machine. Dense medium separation relies solely on particle density for sorting material, limiting the range of minerals that can be used with this process. Ore sorting is a completely dry process which requires no water.

Optical sorter for absolutely pure industrial minerals

Our optical sorters are fitted with colour cameras and lasers or near-infrared (NIR) with hyperspectral imaging (HSI) to identify surfaces exactly. The laser helps to detect the surface structure. Thus it is possible to separate crystalline rock such as quartz or fluorspar efficiently from calcium, talcum or other minerals even when these are the same colour.

While the deposit qualities for mineral raw materials are constantly decreasing, the challenges for sustainable raw material processing are increasing. This applies not only to the demand for minimizing the consumption of energy, water, and reagents, but also to the reduction of residual materials, especially fine and difficult-to-landfill materials. Sensor-based ore sorting can be used as a
