Some of the world class Nickel Laterite ore deposits have Cobalt, Copper and PGE values. Recovering all these metal values in a single refining step is a major challenge. Carbonyl Vapor Metallurgical process is a viable technology to over come this challenge, and also Feasibility Study shows better economics in refining laterite ore via Carbonyl Technology. The technology is a better option for low grade laterite ore as well.

Coltan can be refined economically leaving all the radio active materials behind.
A study has been successfully completed based on CVMR’s proprietary technology on material received from Africa.
