  • Gold extraction from paleochannel ores using an aerated

    Gold extraction at different levels of glycine concentration was tested, and the results are shown in Fig.6. It is clear that gold extraction increases by increasing the glycine concentrationbut the effect is not a monotonic increase in rate and yield versus concentration. I.e. the rate and extraction was less at 37.5 g/L glycine than at 15 g/L.

  • The Selective Leaching of Copper from a GoldCopper

    Recently, a new process using glycine as an alternative lixiviant in alkaline medium for gold and copper extraction has been invented and published [7,9, 15, 17,16,22,24,25]. Glycine has many

  • Gold extraction from paleochannel ores using an aerated

    Leaching gold oxide ores using glycine as a nontoxic lixiviant. The leaching system is suitable for heap and insitu applications. Effects of glycine, temperature, pH and sodium chloride on gold extraction were evaluated. More than 85% gold was extracted with solutions containing 15 g/L glycine at pH 12.5.

  • Amino Acids Key to Gold Extraction Method

    Using the amino acid glycine to extract gold, he says, has many advantages over the traditional cyanide and sulfuric acid treatments. "It's a bulk chemical, it's affordable and it's benign," Eksteen says. "It forms a stable soluble complex with gold, which is soluble in water."

  • The Case for Glycine Heap Leaching mpsinnovation .au

    Gold ore with high cyanide consumption due to nuisance copper Gold projects where the use of cyanide is prohib ited There are vast mineral resources around the world that have remained undeveloped for these reasons. This article outlines the case for glycine heap leaching and proposes a radical re evaluation of these resources.
