Clean TeQ Water Project Updates

DRC CLX Impurity Removal Plant

Clean TeQ Water is pleased to announce the successful handover and customer acceptance of the 20,000 tonnes/day CLEAN-IX® metal impurity removal plant located at ERG’s facility in the Democratic Republic of Congo (DRC).

Clean TeQ Water was engaged by Multotec, Clean TeQ Water’s partner for sales and project delivery in Africa, under a design, procure and construct (EPC) contract, to deliver a metal liquor purification system at ERG Africa’s Metalkol operation in the DRC. The CLX® plant, utilising the Company’s proprietary continuous ion exchange technology, removes the impurity from the liquor at the ERG facility thereby supporting the final cobalt product quality. Over the past few months cold and hot commissioning milestones have been successfully achieved by a Clean TeQ team supporting the customer and end-user in the DRC.

At present, the quality of the feed liquor entering the ion exchange circuit is outside the design specification, primarily due to the performance of existing upstream solids-liquid separation steps. This feed deviation is impacting the efficiency of uranium removal, although the ion exchange circuit is still able to operate at reduced capacity. In the meantime, other purification options have been implemented by the client to ensure cobalt production is not impacted. While any original equipment warranties only apply when feedwater conditions are meeting design specifications, Clean TeQ Water continues to support Multotec and Metalkol in addressing these upstream feed quality issue so that the Metalkol operation can fully realise the benefits of uranium removal from the ion exchange plant.
