    Determination of Gold in Antimony Ores by AAS after

    A method for the determination of gold in antimony ores by AAS was reported in this paper. Samples ignited were decomposed with HCl and Sb was driven off to eliminate the interference effect from Sb on determination of Au by AAS. The optimized conditions and effectiveness for the removal of Sb in samples by HCl were discussed. The method has been applied to the determination of gold in

    Pretreatment of a refractory arsenopyritic gold ore using

    Mar 01, 2015 An arsenopyrite refractory ore was pretreated with NaOH to increase gold extraction. After pretreatment, gold and silver were leached with copper ammonium thiosulfate solution. Thiosulfate leaching of the as-received ore extracted only 21% and 29% of silver and gold, respectively. Up to 81% of the gold and 50% of the silver were recovered after

    Evaluation of Refractory Behaviour of Kaletaş (Turkey

    Gold ores can be broadly categorized as free milling and refractory depending on their response to cyanide leaching (La Broy, 1994, Gunyanga et al, 1999) A gold recovery of 90% can be readily achieved with a conventional cyanide leaching of free milling ores (Rubisov et al, 1996) However, refractory gold ores are often

    Mar 01, 2015 1. Introduction. The recovery of precious metals from refractory ores has been widely investigated due to depletion of the deposits from which gold can be easily leached (Abrantes and Costa, 1996, Ofori-Sarpong et al., 2011).There are numerous causes and degrees for refractory behavior: the presence of carbonaceous matter, passivating films, finely disseminated gold particles in solid solution
