Introduction Technological developments and changes in metal market increased the demand for rare earth elements and their importance significantly. In this content, Scandium became substantial as one of the rare earth element, which is commonly used in military, fuel cells and aircraft industry. Geologically, Scandium can be deposited in different formations such as placer deposits and weathered crust elution deposits (ion adsorbed clay deposits). The objective of this study is determining the possibility of obtaining a Scandium (Sc) pre-concentrate from altered serpentinite mineral, which scandium is adsorbed on as a result of weathered crust elution, by making attrition scrubbing process. The motivation of obtaining a pre-concentrate is preparation of a feed, relatively enriched in scandium content for increasing the efficiency and effectiveness of subsequent hydrometallurgical processes. Through attrition scrubbing process, the rejection of gangue minerals that would cause negative impacts during hydrometallurgical treatment, at the highest possible extent, is also targeted. Pre-concentration work is focused on application of attrition scrubbing process to recover scandium at possible highest rate from altered serpentinite mineral. .
