    Once extracted, the gold is refined with one of four main processes: floatation, amalgamation, cyanidation, or carboninpulp. Each process relies on the initial grinding of the gold ore, and more than one process may be used on the same batch of gold ore. Mining

    processing techniques required, gold . ores are commonly classified into two major ores. Typically, freemilling ores are defined as those where over 90% of gold can be recovered by conventional cyanide leaching. Refractory ores give low gold recoveries only with the use of significantly more reagents or more complex pretreatment process. 1

    Extraction of gold and other precious metals from their ores by treatment with mercury is called amalgamation. Gold dissolves in aqua regia, a mixture of hydrochloric and nitric acids, and in sodium or potassium cyanide. The latter solvent is the basis for the cyanide process that is used to recover gold from lowgrade ore.

    Typically, mill tailings range from sand to siltclay in particle size (40 to 90 percent passing a mm (No. 200) sieve), depending on the degree of processing needed to recover the ore. The basic mineral processing techniques involved in the milling or concentrating of ore are crushing, then separation of the ore from the impurities.

    Rcovery of gold in pyritic ores

    In most instances, visible gold can not be seen under microscopic examination of pyrite gold ores. However, if the ore is ground to 200 mesh, most times, a few specs of gold can be visibly seen under microscopic examination. Based upon numerous case studies, it appears that gold particles in pyrite are generally fine, ranging from 75 microns ...
