The presence of cyanide soluble copper in the cyanidation of gold-copper ores and concentrates significantly increases the cyanide consumption in order to achieve sufficient gold recovery. In addition, cyanide recovery or cyanide detoxification/destruction processes are also required which adds extra cost to the process. This research introduces a leaching approach to extract gold, silver and copper from gold-copper ores and concentrates using a synergistic lixiviant leaching process using glycine in the presence of low concentrations of cyanide. The effects of glycine and cyanide concentrations on gold, silver and copper leaching kinetics and recovery were studied. It is shown that, in the presence of glycine, gold, silver and copper extraction increase significantly in solutions containing copper-cyanide species at a very low, or zero, free cyanide concentration.
From humble beginnings, a proud story of growth, vision, commitment, inspiration and innovation. Our roots are deep, our standards are unmatched, our dedication is timeless.
Our clients cover a wide range of sectors including local, state, territory and Commonwealth governments, retail and sales, hospitality, commercial, health and aged care, industrial and manufacturing, civil works and defence, as well as medium-density residential, in the Northern City and South England.
Focusing on medium to large-scale commercial construction projects, we work with both investors and developers to create landmarks that make an impact.
