Leaching of nickel and copper from soil contaminated by ...

The described lysimeter experiment has shown that the most leaching rate of nickel and copper was observed when irrigation was of slightly acid conditions (pH 5–6). This seems to be the essential evidence that formation and leaching of organic metal compounds are the determinants for leaching of heavy metals from soils, but not the precipitation acidity.

The reported irrigation flow flux was 10 l/hr/m 2, which is at the high end of conventional copper and gold heap leaching practices. Nickel laterites have a rather high acid consumption (hundreds of kgs. of acid per ton of ore versus about ten kgs. per ton of copper ore) because of the soluble magnesium content,...
