CRC ORE
172 in material that was originally designated as mineralised waste ( not even ore feed ). A 450 tons per hour Metso Loko-Track mobile screening plant was deployed on site to assist in the production scale testing . The trial focused on upgrading this and other waste targets from the pit to determine if a metal-rich stream could be generated that could be economically combined with Run of Mine ( ROM ) feed to the concentrator .
“ So far , results show that by applying Grade Engineering to areas previously designated as ‘ mineralised waste ’, 25 % of the material has a feed grade to the mill some 2.5 times higher than ROM ore ,” says Dr Adair . “ There is now the potential to convert this waste material into high grade ore-feed , with associated opportunity to increase metal production and reduce process power and water intensities . We ’ re now in the process of operationalising the process for the site going forward .”
MSC Operations Director Dave King believes the opportunity for the mine is huge . “ One of the exciting things about Grade Engineering is that when people hear about it , they think that it ’ s ‘ what
