From Multicom FAQ factsheet 2
1. ARE YOU USING PROVEN TECHNOLOGY?
i) The process from mining to the final product (vanadium pentoxide) is in three main parts. i) Strip or panel mining is similar to the method used in bauxite mining, which has been operating in other parts of Australia for more than 50 years and is well suited to progressive rehabilitation. Topsoil is removed and stockpiled nearby for use in rehabilitation.
ii) The exposed ore is excavated and washed with water in a trommel, to separate the larger particles (about 85%) from the finer clays (about 15%). The larger particles and overburden are then returned to the previously mined area, ready for rehabilitation.
iii) The finer clays are processed to extract vanadium. Multicom’s engineering team is currently optimising the processing options as part of the Prefeasibility Study. Each of the processing circuits being considered are proven technologies, which are in use across numerous other successful resource operations globally. The combination of these technologies for use on the Saint Elmo Project is currently being tested and validated by Multicom, to verify historical test work previously successfully completed by others.
