Abstract of Paper presented to NASA Conference in Washington DC August 2006: "Use of CVMR® Technology on Mars" (Presented by Dr. Dmitri Terekhov, CVMR®’s Vice-President, Research & Development.)


Chemical Vapour Metal Refining (CVMR®) is a process of extraction and refining of metals from ore, ore concentrates or recycling materials. The CVMR® process was developed, in its basic form, at the beginning of the 20th century. At present, more than 20% of worldwide annual nickel production is refined using carbonyl technology, a variety of CVMR® process. Carbonyl technology (the Mond process) is a vapour metallurgical refining method based on the ability of nickel, iron, cobalt, etc. to form volatile metal carbonyl compounds. Carbonyl process was suggested as the best method of refining metals on Moon and Mars. We propose to combine metal refining and production of metal parts in the same process. As part of CVMR®’s research for production of high value products (powders, foams and net shapes) from nickel, we have developed a self-contained unit capable to perform extraction of metals and manufacturing metal net shapes at the same time. What is missing, is a carrier to deliver an adaptation of such unit to the other heavenly bodies to begin mining and production of metal structures. In this presentation we review the feasibility of usage of self-contained units to space mining, including the chemistry and engineering challenges. The presentation emphasizes extraction of base metals such as Fe and Ni and production of iron or stainless steel structures in situ. The paper also reviews an application of CVMR® technology to other metals.
