Explained in plain English
What is a 'concentrate'?
A concentrate is a raw mineral ore that has been partially processed to remove impurities, making it richer in the desired metal. It's not the final refined metal but a step towards it. Congo wants to do the full refining itself, rather than just selling these semi-processed materials.
