Column tests were conducted to evaluate the amenability of poor Greek laterites to with dilute sulphuric acid at ambient temperature. The ore tested was limonitic laterite with less than 1% and it was subjected to a suitable pretreatment with water prior to it being loaded into columns, following findings of ...

Nickel ores This method is an acid heap leaching method like that of the copper method in that it utilises sulfuric acid instead of cyanide solution to dissolve the target minerals from crushed ore. The amount of sulfuric acid required is much higher than for copper ores, as high as 1,000 kg of acid per tonne of ore, but 500 kg is more common.
