Electronic Ore Sorting Copper Ore

12/06/2017  Mineral Sorting Techniques. The plant tests demonstrate the feasibility of using electronic sorting to preconcentrate native copper-bearing materials. Double-pass sorting, however, is necessary to achieve adequate recovery. Copper size and association are found to be important in copper recovery. Tamarack conglomerate ore contained the highest percentage of fine copper

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 hand-sorting and gravity concentration. They resulted in high losses of copper.

copper ore sorting copper - shrawleyparishcouncil.uk

Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals, Initial concentration techniques included hand sorting and gravity concentration. They resulted in high losses of copper. Consequently, the development of the froth flotation process was a major step forward in mineral processing. It made possible the development of the giant Bingham

Ore sorting: Efficiently optimise the treatment of ores in ...

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 entire processing line can be planned in semi-mobile form and consists only of crushers, screens, belts and ...

01/11/2016  The MW-IRT sorting technique presented was not meant to be a diagnostic tool for the accurate determination of fragment-by-fragment copper grade, but rather to provide a means to discriminate fragments with higher or lower copper content to form the basis of a potential separation. In this respect, an attractive separation could be proposed for many of the ores tested, either to remove

Sorting: Possibilities, Limitations and Future

Ore sorting techniques give an opportunity to remove gangue and below grade ore prior to main processing step. However, sorting can be considered and successfully utilized for secondary processing, i.e., waste separation and recycling. On the contrary, costs for installation and operation of sorting machine(s), feeding, sizing and preparation of the feed, as well as loss of valuables to waste ...

Mineral processing - Wikipedia

Modern, automated sorting applies optical sensors (visible spectrum, near infrared, X-ray, ultraviolet), that can be coupled with electrical conductivity and magnetic susceptibility sensors, to control the mechanical separation of ore into two or more categories on an individual rock by rock basis. Also new sensors have been developed which exploit material properties such as electrical ...

Copper Processing: The Quest for Efficiency at Scale E MJ

Sensor-based Ore Sorting One of the best ways to reduce energy and water consumption in concentration or improve leaching is to remove as much gangue as possible as early as possible. “I’m really optimistic on preconcentration and ore sorting,” Boylston said. “The has been used in many places, but it’s not mainstream yet. I think the biggest reasons for that are scaling ...
