    The gold mine pool leaching process has strict requirements on the dosage of cyanide solution; too much is of a waste and too little can't guarantee the leaching effect. When using ExAurum eco-friendly gold leaching reagent, the requirements can be appropriately relaxed in terms of dosage,and the same leaching effect of cyanide can be obtained, which saves cost and reduces environmental pollution.

    2019-9-11  Anglo Asian Mining’s Gedabek mine is situated in the Lesser Caucasus mountains in Western Azerbaijan. The ore body is a complex copper-gold porphyry deposit, comprising intermixed oxidized, transition and sulphidic gold and copper-bearing ores. Gold in the sulphide ores is generally not refractory and is recoverable by cyanide leaching, but the secondary copper minerals, which are also cyanide soluble, lead to high cyanide consumptions. Ore processing at Gedabek is by agitation leaching for high grade ore (>1g Au/t) and heap leaching for lower grade ore. In order to cope with the high copper concentrations in the cyanide leach liquors, a unique combination of resin-in-pulp for selective gold extraction and SART processing for copper removal and cyanide recovery is used. In 2015, a flotation plant was added to treat the tailings from the agitation leach
