This treatment processes pre-concentrated ores in bulk by acid or acid/oxidising agent leaching. The solution is recovered either directly or after a cascade wash/clarification. Most of the time, purification/concentration is carried out by selective precipitation of impurities. It is at this stage that recyclable impurities are recovered.
