01.11.2019Preconcentration of low-grade Cu–Co ores using gravity separation methods is also of growing importance for a number of concentrators in the DRC, as it contributes to making the beneficiation of previously uneconomic ore deposits possible, and significantly reduces the processing time and costs. HMS and spirals are now installed at a number of concentrators.

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 technology has been used in many places, but it's not mainstream yet.

As mineral deposits become more complex, difficult to process and contain lower grades, extraction of resources require costly mining and processing of increasingly larger volumes of rock per tonne of product. The aim of pre-concentration is to remove barren material as early in the mining process and at as coarse a particle size as possible. This has the main objective of
