Summary
The application of chlorine extractive metallurgy was evaluated for three applications: recovery of pure copper from chalcopyrite ore, recovery of pure chromium from chromite ore, and recycling of contaminated scrap metals. Main emphasis was given to chalcopyrite processing, and a unique process with many attractive features was proposed. Relative to energy conservation, the new process has the potential for a reduction factor of 5 to 10 in the energy consumption for recovery of copper metal from chalcopyrite. Some experimental chalcopyrite chlorinations of a scoping nature were also carried out. For chromium production, chlorination offers the potential of a reduction factor of 2 in energy consumption, as well as production of very low carbon, pure chrome that may have useful metallurgical advantages. Chlorination is particularly suited for the recycling of metals from low-grade contaminated scrap containing many different metals. Energy savings by scrap recycling is indirect; it reduces the amount of new metal that must be produced by mining, concentration, and smelting.
