laterite crushing process
Nickel and Cobalt Production. Laterite ores are upgraded before smelting or leaching. The upgrading entails gently crushing and/or grinding the ore and then separating the resulting small, soft, low-density Ni-rich laterized mineral particles from large, hard, dense, Ni-lean, unlaterized precursor rock and by-product laterization products, e.g., quartz [4, 5].
