  • Cyanidation of gold ores containing copper, silver, lead

    While high gold recoveries (gt; 90%) from free milling ores can be readily achieved, refractory gold ores are often characterized by the low gold extractions (5080%) within a conventional cyanide leaching process (Rubisov et al., 1996, Adams, 2005, Celep et al., 2009). The presence of preg robber components such as carbonaceous matter, sulfide minerals and aluminosilicate have more influence in decreasing of
