Leaching and ion exchange based recovery of nickel

2020-1-1  The proposed flowsheet for Ni leaching from such low grade ore by alkaline glycine leaching consists mainly of heap leaching followed by metals recovery (Ni, Co and Cu) by resin in column (CIC) and recycling glycine solution to the leaching step. Fig. 12 shows the proposed simulated heap application set up to treat such deposits. Bench scale results will provide a basis to investigate nickel and cobalt recovery from various sulfide resources using a benign alkaline leach

WO2001075184A2 - Heap leaching of nickel

A process is provided for heap leaching ore to recover nickel. The process is particularly effective for ores that have a tangible clay component (i.e., greater than 10 % by weight). The process includes sizing the ore (where necessary), forming pellets by contacting ore with a concentrated sulfuric acid lixiviant and agglomerating. The pellets are formed into a heap and leached with a ...
