CTT produces cobalt in the form of broken cathodes, with capacity of about 1,800 tonnes per year. The units are marketed by Switzerland-based Manatrade, of which CTT is a fully-owned subsidiary.

The price for cobalt standard grade, in-whs Rotterdam, which incorporates CTT broken cathodes, was $16.30-16.70 per lb on Monday, down from $16.85-17.15 per lb a week ago as a result of weakening demand. The prices will next be assessed later today.
