Bulk ore sorting improves profitability and sustainability
Bulk ore sorting improves profitability and sustainability. Highgrade ore deposits are depleting fast. Consequently, the mining industry has to take on lowergrade deposits, which are more difficult to extract. These deposits require the mining, movement and processing of larger volumes of material per ton of valuable mineral.

Ore sorting Preceding processing Ausenco.
Guthrie said the second case sorting of ore to increase grade and reduce subsequent processing and transport costs is generally only economically favourable if the processing and ore transport costs are high (in relation to head grade) and the recovery of values is also high (eg >95%) .

Sorting out waste CSIRO
It illuminates batches of ore with short pulses of radio waves, assessing ore grade and enabling high tonnage sorting at extremely high speeds. Sorting ore based on magnetic resonance signatures NextOres ore sorter is able to detect the magnetic resonance signatures of many minerals, including the most common economically significant ironand copperbearing minerals.

Use ore sorting equipment to concentrate ores and cut
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.

Copper extraction Wikipedia
However, as the concentration of copper in the ore bodies decreased, the energy costs of smelting the whole ore also became prohibitive, and it became necessary to concentrate the ores first. Initial concentration techniques included handsorting and gravity concentration. They resulted in high losses of copper.

ORE SORTING BTW Plant Solutions
ore sorting is a process for upgrading mineral bearing materials at large particle sizes, typically between 150 and 10 mm. Some particularly high value materials justify sorting down to even smaller sizes. [It] involves evaluating the mineral content of individual rocks as they pass through the ore sorter

COPPER Copper production TU Delft
Copper concentrators typically treat up to 100 000 t of ore per day. They are located directly at the mines to achieve low transport costs. The copper recovery efficiency is over 90 %. About 95 % of the ore input goes into the tailings, which are stored in large dams near the mine and are used for water recycling to the flotation stages.
