Bioleaching of Lateritic Nickel Ores | SpringerLink

Pressure acid leaching has been applied to the Caron process to reduce high-energy consuming phases in direct ore leaching. Direct leaching eliminates the need for drying and reduction steps, which then leads to energy savings (Buyukakinci, 2008).The acceptable nickel content in this method is 1–5% (Dalvi et al., 2004).Also, the crushed ore is dissolved directly with sulfuric …
