Pilot Flotation & Beneficiation Pilot Flotation & Beneficiation

Core provides pilot flotation programmes for our clients across a wide range of target minerals. Core’s specialist flotation metallurgists can assist with design of the programme, and preparatory bench-scale testwork to establish and optimise flotation conditions.

Our dedicated pilot flotation area is capable of treating several tonnes of material, and can include crushing and grinding of drill core sample (see here for pilot milling capabilities). Core has a wide range of pilot grinding and flotation equipment available for the execution of an integrated pilot flotation programme, including both conventional and Jameson and column cell flotation.  Core also provides screening and magnetic separation capabilities for beneficiation pilot programmes. Ore sorting testing can be conducted by Core through our network partners.
