Ore sorting has a potential to upgrade a range of mineral ores to processing plant leading to substantial reduction in downstream costs, limiting environmental harm by reducing mine wastes and improving ore quality and mineral recovery. Ore sorting techniques give an opportunity to remove gangue and below grade ore prior to main processing step.
There are several pre-concentration technologies that can be applied at each stage of mineral processing and the ideal operation should combine those tools to remove the liberated gangue at multiple stages of the processing plant in order to achieve the most sustainable process (ie bulk/particle ore sorting, selective breakage, coarse flotation).
Bulk ore sorting is a key means of addressing these areas of concern. The concept of ore sorting is broad, frequently including sorting by particle size, grade and mineralogy across various mineral processes. The installation of an on-line elemental analyzer facilitates early, accurate measurement of material grades transferred to the process ...

Many mineral processing operations are taking a hard look at ore sorting to improve their bottom line. Even the slightest sorting inefficiencies can lead to huge financial loss, not to mention easily preventable downstream and environmental impacts.
TOMRA's sensor-based sorting has been a proven concept in minerals processing, recycling, and the food industry for nearly 50 years. It can reduce specific energy consumption by 15 percent, as well as the amount of water used by three to four cubic meters per tonne of ore.
Ore sorting is a very broad concept that includes sorting by grade, particle size and mineralogy across many different mineral processes. Installing an online elemental analyzer enables early and accurate measurement of the grade of material being sent to the process plant and enables a decision to sort material that is below target grade and ...
Ore Sorting vs. Dense Medium Separation In Mineral Processing Written By: Team Sepro | Date: 18.07.19 For successful mineral processing design it's critical to evaluate the possibility of preconcentration or waste diversion before grinding.
sizing and sorting process help removing larger particles and other unnecessary impurities in the ore material. Through those process, ore particles with good particle size are obtained, and the efficiency and benefit of beneficiation are improved.
The integration of the ore sorting plant into the main processing plant was completed smoothly, with TOMRA's full involvement in the ore sorting plant design. TOMRA also had a team onsite for the first three months of operation to ensure a seamless transition, and will continue to provide ongoing support for the entire life of the equipment.
Summary. The contribution of X-ray ore sorting to the efficiency of mineral processing is growing, and TOMRA's new COM XRT 2.0 sorters are taking the value added by this technology to another level. com-xrt-2_500px-540388.jpg. This upgraded model features higher belt speed and throughput, which translate directly into increased productivity ...

Ore sorting has been used in mineral processing since the dawn of mining (Agricola, 1556), allowing materials to be separated into valuable and gangue minerals. In the early times, particles would be
Sensor-based technologies: Ore Sorting • Sensor-based sorting is typically used for particle sizes ranging between 0.5 to 300 mm • Completed prior to the application of fine comminution and chemical processing techniques. • The goals are to remove waste before it enters production and recover the viable ore.
The tests have confirmed that simultaneous sorting of two size fractions is possible on the sorter, allowing a single machine to sort both sortable size fractions (10 mm-25 mm and 25 mm-75 mm), Northern Minerals says. The sortable fraction (>10 mm material) of Wolverine ore can be successfully sorted (90% TREO recovery in 50% of the mass) and ...
Mineral processing equipment supplier Outotec and mining materials handling company TOMRA Mining have agreed to continue the non-exclusive cooperation to supply particle ore sorting ...
By using ore sorting equipment, ore concentrates can be created at very low cost in small or remote mining installations. The entire processing line can be planned in semi-mobile form and consists only of crushers, screens, belts and sorting machines. This allows immense cost savings for transport, since the waste rock is disposed of on-site.
Manganese minerals are weak magnetic minerals (specific magnetization coefficient X=10×10-6~600×10-6cm3/g), can be effectively recovered in a strong magnetic field magnetic separator with a magnetic field strength of Ho=800-1600kA/m (10000-20000oe), and the grade of manganese can generally be increased by 4-10%.
The ore sorting process helps concentrate the metals of commercial interest from the Kutcho deposit, which are principally associated with high density sulphide minerals. Rocks are individually scanned, and low grade (low density) waste material is selectively diverted away from downstream processing using compressed air jets.

TOMRA Sorting Mining designs and manufactures sensor-based sorting technologies for the global mineral processing and mining industries. As the world market leader in sensor-based ore sorting, TOMRA is responsible for developing and engineering cutting-edge technology made to withstand harsh mining environments.
To date, most members of the mining and mineral processing industry have been aware of ore sorting and the benefits it offers. Introduced nearly thirty years ago, sorting was first adopted by the diamond and precious metal industries. In these sectors, the value of the minerals sorted was so high that the capital payback could be easily justified.
Ore Sorting helps the economics of mining when ore becomes diluted by country rock because of narrow slopes or because of weak wall rock, or when it naturally contains barren material which is distinguishable from the ore, sorting and rejecting the worthless rock may be economical. This is done in a casual manner at some small mines and on a large scale at others, as was the case at …

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 ...
Ore sorting as a class of technologies addresses these issues by reducing the amount of material fed to the milling circuits, eliminating much of the waste before any further capital or operating expenses are invested into its processing. In the simplest sense, ore sorting constitutes a sensor, a processor, and a sorter .
Bulk ore sorting may be used to increase the production rate, reduce the size of downstream processing equipment, or upgrade uneconomic or marginal reserves improving the resource utilization.
