If the ore is a high grade, it may be feasible to tank leach it. By high grade, it would

Gold Absorption Carbon Genuine Shell Carb

The CIL process is frequently used when native carbon is present in the gold ore. This native carbon will absorb the leached gold and prevent its recovery. This phenomenon is referred to commonly as “preg-robbing”. The carbon added in CIL is more active than native carbon, so the gold will be preferentially adsorbed by carbon that can be recovered for stripping. The CIL

Photos of gold ores, quartz, telluride gold ore and gold

Within gold ores, the element occurs in nature chiefly as native gold, which is by far the most common gold bearing mineral. In various gold ores, the native gold commonly occurs as tiny particles contained within sulfide minerals such as pyrite. Iron pyrite is an exceedingly common associate with gold, but it also serves as a reducing agent. Therefore whenever gold is found
