Metso has launched its new Cu POX leaching process for the copper extraction industry. The company says that, as ore compositions change due to depletion of deposits and increasing environmental and efficiency demands, this solution not only maximises copper recovery but also reduces environmental impact.
Nickel Asia Corp. (NAC) says that it has completed the sale of its 15.6% stake in Coral Bay Nickel Corp. to its Japanese partner Sumitomo Metal Mining. Nickel Asia says that the sale has been due to “unfavourable market conditions” for the high pressure acid leach (HPAL) nickel processing plant. Although Coral Bay is regarded as one of the most efficient HPAL units in the world, nickel prices have been extremely volatile over the past few years and stood a 4-year lows in January at around 15,000/t, their lowest level since September 2020. Nickel Asia still owns a 10% stake in the Taganito HPAL Nickel Corp.
