It estimates that it can recover 72% of the copper inside the rock using its proprietary leaching process, without the need for a smelter or costly and expensive refinements. There's no denying, that this new copper-leaching technology has a lot of potential even if it is half as effective as claimed here. Let's find out the company behind it.

WhatsApp: +86 18221755073"At Nuton's core is a biological leach process that transforms copper-bearing rock or mine waste into 99% pure copper cathode. "Our leaching process starts by creating a heap – a very large pile of crushed rock. Depending on the site, that could be newly mined ore or previously mined rock that has been discarded as waste.
WhatsApp: +86 18221755073Copper doesn't evaporate. It is a metal. It has to be washed out; chelated; ionically changed, for it to come out of the rock. Letting rock sit for a long period of time that has been treated with copper is called rock containing copper. No change will occur over time in regard to copper content.
