01-02-2014· Microbial pre-treatment of refractory carbonaceous ores. Some gold ores have a carbon content that inhibits gold recovery using leaching or lixiviant processes and thus renders them refractory (Brierley and Kulpa, 1993). These include refractory carbonaceous and/or carbonaceous-sulphidic ores.

Refractory Gold Any ore that is not readily amenable to recovery by conventional cyanide leaching at a reasonable grind size can be considered refractory. The three primary factors that cause gold ores to be refractory are: Physical encapsulation – Extremely fine (<10 µm) particles are locked within an impervious, unreactive mineral.
