The most effective way to remove both kaolinite and goethite is by washing, followed by attrition scrubbing and desliming through removal of clay-rich super fines in hydro-cyclone. Processing of bauxite for smelter grade alumina is quite sensitive to bauxite recovery and total cost for processing of ore, particularly in wet beneficiation.

Our laboratory has the capability to create multi‑stage pilot scale circuits to treat bulk samples (80‑100 tonnes) for process testing and circuit optimisation. We then deliver concept, pre-feasibility and feasibility studies as well as cost effective flowsheet design to safely and efficiently extract the iron ore.
The MP618 ash beneficiation technology can be delivered as a portable or stationary system depending on client requirements. Charah Solutions' recently completed unit operating in Louisiana processes utility generated ash and can be used to test site-specific fly ash, allowing for a complete analysis of material both pre and post processing.
