Victor Mann, RUSALs Technical Director, commented: The fact that UC RUSAL has its own raw materials and a unique production process for making scandium oxide, master alloys and aluminium scandium alloys will allow the company to bring a brand new value-added product to market, for which there may be a lot of demand across a broad range of mechanical engineering industries.
The Lucknow mineralisation has emerged as larger and higher grade than our existing Kokomo scandium resource to its north, and it is not unreasonable to expect that the NORNICO Stage 1 plant could ultimately, within the decade, convert from a Ni-Co-Sc ore facility to a predominantly Sc ore operation and a major long term world supplier of scandium oxide".
