Ivanhoe Mines Co-Chairs Robert Friedland and Yufeng “Miles” Sun say that the Kamoa-Kakula Copper JV has agreed to immediately proceed with orders for the long lead time equipment for the second, 3.8 Mt/y concentrator module at the Kakula mine in the DRC, which will double the mine’s processing capacity from 3.8 Mt/y to 7.6 Mt/y.[…]

Sensor-based ore sorting test work from TOMRA Sorting Solutions has shown the potential for lowering the planned capital expenditure and operating costs associated with developing the Santa Comba tungsten-tin project in Galicia, Spain, project owner Rafaella Resources has reported. The “exceptional” ore sorting results showed a 50% rejection of un-mineralised rock and an approximate doubling[…]
