In the Congo, cobalt is found in various forms, each leading to a different refinement process. The most common process includes hydrometallurgical refining to directly produce either a cobalt cathode or hydroxide. [4] In other processes, the mined ore is agitated to separate the minerals in a process called separation flotation.

Avima Iron Ore has initiated an arbitration process against the Congo Republic and is seeking $27bn in damages for cancelling its mining permit last year. The arbitration has been filed by the company's subsidiary Avima Fer Congo and its affiliates before the International Court of Arbitration of the International Chamber of Commerce (ICC).

This means that properly selected chemicals in the flotation process is a very important factor that can minimize the toxicity of a generated waste (Brooks et al., 2019) It was also shown that the ion exchange process can be effective in purifying water after the zinc and lead ore flotation process (Woynarowska et al., 2011).
