  • The composite gold-antimony vein deposit at

    The Kharma antimony deposit in the Cordillera Oriental, Bolivia, is representative of vein-type antimony deposits that have stibnite as the only mineral of economic interest and a low gold content. In this deposit, recovery of gold is difficult because it is not known exactly where the gold is located within the ore shoots or the manner in which it is present in the main minerals of the deposit.

    Gold ores are commonly classified by the metallurgist into two major categories: free-milling and refractory ores. Typically, free-milling ores are defined as those where over 90% of gold can be recovered by conventional cyanide leaching. Refractory ores are defined as those that give low gold recoveries or give acceptable gold recoveries only
