• Carbon for Recovery of Gold

    Activated carbon is widely used for gold recovery from cyanide leach liquors via carboninleach (CIL) or carboninpulp (CIP) technology. From all the base metals cyanide complexes typically present together with gold in the leach liquor, only copper, and to a lesser extent nickel, are loaded onto activated carbon(6). The loading behaviour of copper cyanide onto activated .

  • Soil Organic Carbon Pulp Paper Activity Module

    RESEARCH: The activity modules refers to research conducted by the Natural Resources Institute Finland which found that 60% of the carbon is consumed by soil microbes and 40% of it is stored in soil for decades or even centuries. If these industrial residues aren't used as soil improvers, they are typically incinerated by pulp and paper mills, especially in Europe. In the .

  • The Metallurgy of Cyanide Gold Leaching – An Introduction

    A paper published by L. Elsner in 1846 first correctly identified the chemical reaction that forms the basis of all gold cyanide leaching processes: 4 Au + 8 NaCN + O 2 + 2 H 2 O → 4 Na [Au (CN) 2] + 4 NaOH. The equation is well known, but the successful appliion of this reaction in a gold mining operation is rarely straightforward.
