Leaching or Smelting; SX/EW or Electro Refining; Copper is processed in several stages from extraction and crushing of the ore to electrolytic refining, which allows obtaining % pure Copper Cathodes. The beginning for all copper is to mine sulfide and oxide ores through digging or blasting and then crushing it to walnutsized pieces.

PIONERA's BioPolymers are highly effective for use in leaching ore concentrates. PIONERA products are modified natural polymers acting as a dispersant that can prevent elemental sulphur from coating the desired ore particles. Sulphur formation on the ore particles can interfere with the extraction process and result in decreased metal recoveries.

Copper ore leaching processing

Copper ore leaching processing

The coarser ore goes to the heap leach, where the copper is subjected to a dilute sulfuric acid solution to dissolve the copper. Then the leach solution containing the dissolved copper is subjected to a process called solvent extraction (SX). The SX process concentrates and purifies the copper leach solution so the copper can be recovered at a ...

ProcessEdit. The role of the bacteria is the further oxidation of the ore, but also the regeneration of the chemical oxidant Fe 3+ from Fe 2+. For example, bacteria catalyse the breakdown of the mineral pyrite (FeS 2) by oxidising the sulfur and metal (in this case ferrous iron, (Fe 2+ )) using oxygen.

Oxide copper was first discovered at Nifty in 1981 by WMC Limited ("WMC"). Drilling of the oxide resource ultimately led to the discovery of the deep sulphide resource in 1983. WMC commenced an open pit, heap leach, SXEW operation on the relatively high grade part of the oxide mineralisation in 1993.
