LEACH PILOTPLANT FACILITY HIGHPRESSURE ACID LEACHING (HPAL) Major reserves of nickel are contained in laterite ores, which have traditionally been treated by pyrometallurgical methods. Hydrometallurgical treatment, by direct acid leaching of the ore at temperatures above 240°C, is however an alternative treatment option for several new projects. The basic steps in the process are: There are ...

metal ores (<1% copper, <1g/ton gold, < % nickel) previously considered uneconomical, became feasible with introduction of heap leaching technologies (Marsden, 2009). In consideration of ore types, a generalized diagram showing the applicable ore beneficiation technologies for oxide and sulphide ores versus ore grade is given in Figure 2.

In the first stage (leaching), acidic water (dilute sulfuric acid) is distributed over 60foot high ore pile layers by wabblers, drip irrigation devices or sprinklers (rain birds), and allowed to percolate through the pile dissolving copper as it penetrates. The copperladen water or "pregnant leach solution" exits from the bottom of the ore pile or dump and flows to a collection pond from ...

Leaching and washing of leached solids from the percolation tanks by the crosscurrent methods will inevitably result in weak solutions of the solute. The strongest solution will result if a countercurrent scheme is used. Here the final withdrawn solution is taken from contact with the freshest solid and the fresh solvent is added to solid from which most of the solute has already been leached .
