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 down to 2 or 3 microns. The .

Modern gold deportment studies
The most efficient gold extraction processing route is directly related to the inherent mineralogical features of the gold ore being processed. The mineral assemblage determines the performance of all chemical and physical processes involved in gold extraction ( Chryssoulis and Cabri, 1990; Marsden and House, 1992; Chryssoulis and McMullen, 2005). It is therefore .
VEIN DEPOSITS
Minor amounts of sulphide minerals and other gangue minerals such as calcite and various clay minerals often occur; gold is rarely visible. Veins range in thickness from a few centimetres to 4 metres, the average mining width being around metres ( at Bridge River). They can be several hundreds of metres long and extend to depths in excess of 1,500 metres. .
What is Clay Bar Detailing, and How Does it Work?
· Clay bar detailing takes place after a wash and dry, but before a polish. Using a clay bar is pretty simple. We just need 3 things: First, we apply the detailing spray or clay lubricant to a small area of your car. This is important: without some sort of lubricant, the clay could damage your car's paint. Then we slowly glide the clay along ...
