A small-scale Pilot-Plant test was performed in 2008 (Figure 4). According to the results, the production of high quality copper concentrate and saleable nickel-cobalt concentrate is verified.
Concentrate customers will be in Finland, Europe, Russia and/or China. Copper concentrate (+Au+Ag) is now at an acceptable price level. Cobalt price has exceeded 50 000 usd/t level, but nickel price, recently under 10 000 usd/t, is not yet satisfactory.
