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.

23-10-2018· The principle of operation of the machine is to measure the light reflectance characteristics of each and every particle, and as a result is suitable for processing a wide range of minerals that show a reliable and consistent optical difference between ore and waste. A prerequisite for efficient sorting is the preparation of the feed material.

What is Sorting? Ore sorting is a mineral concentration process where individual ore particles are separated from the unwanted material based on some physical (or chemical) property Ore Sorting can be used for: Pre-Concentration / Waste Rejection Ore-type diversion Concentration to product Sensor Based Sorting is the automation of

Optical sorting and lasers are very well suited to the detection of ores with different colours, such as copper oxide, or crystalline structures in quartz. By using ore sorting equipment, ore concentrates can be created at very low cost in small or remote mining installations.

The optical sorting by NIR can be applied nevertheless. Due to the mineralogical differences between spodumene and quartz / feldspar, an identification of spodumene is possible. The identification module idSpodumene was developed for identification of waste rock

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.

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

Successful ore sorting of this nature relies on feed prep and ore heterogeneity. While you can’t control the mineral makeup of the feed, you do have significant control over particle size. Control Particle Size for Improved Mine Economics. Effective ore sorting is dependent on the heterogeneity of the feed.
