The principal gold minerals that affect the processing of gold ores are native gold, electrum, Au-Ag tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the Au-Ag tellurides, and very fine-grained gold (<10 µm) locked ...

Using this hypothetical value of 1 ozt./ton, each pound of ore would contain approximately 0.0005 ounces of gold. Now let's assume that gold is valued at $1500 per ounce. That would make the gold in a one pound ore sample worth approximately 75 cents, and this is assuming that the ore is extremely rich.

There are three main classification categories for gold ores, namely free-milling, refractory and complex ores (Brooy 1994). Free-milling gold ores are defined as those from which standard cyanidation (which takes about 20-36 h) can extract more than 90% of the gold, under the condition that the ore size is p80 = (− 75 μm) (Zhou et al. 2004).

On this page, we summarize some of the techniques in mercury-free artisanal and small-scale gold mining. Using Concentration Methods Concentration means increasing the amount of gold in ore or sediment, by selectively removing lighter particles. If employed effectively, concentration methods can eliminate or greatly reduce the need for mercury.

Free-milling ore is the name for when gold can be recovered by crushing, grinding and cyanidation (treatment with a dilute cyanide solution) without additional processing. In refractory ore the gold is locked in sulphide minerals, so to achieve satisfactory levels of gold recovery additional processing is required before cyanidation.

Pyritic ores are free-milling to mildly refractory, or rarely moderately refractory. Pyrite in pyritic ores contains negligible to low levels of submicroscopic gold (<5 ppm). Other reasons for refractory behaviour in pyritic ores include very fine-grained native gold inclusions in pyrite, or the presence of gold-bearing tellurides.
