Producing nickel matte in this way is CO2 intensive, page-3

All smelters use coal to turn ore into metal. This is a new process able to produce nickel matte using the existing rotary kiln, and at only $1 million conversion costs seems straightforward process of adding another material into the feed lines. So many analysts still think it is the HPAL process. This is why nickel mines will succeed They saw an opportunity and are making the most of it. In 5-8 years the new technology in batteries might not require nickel but in the mean time NIC can supply the market as a low cost producer. I wouldn’t be surprised if NIC find a way of extracting gold or some other valuable mineral from the process in years to come such has been their forward thinking. GLTAH.
