Hard rock ores have formed the basis of the majority of commercial gold recovery operations since the middle of the 20th century where open pit and or sub-surface mining techniques are used. Once the ore is mined it can be treated as a whole ore using a dump leaching or heap leaching processes. This is typical of low-grade, oxide deposits.

Gold deposits can be grouped into two primary classes: placer deposits, where the gold is exposed from weathering and erosion, and hard rock, where the gold is still trapped within the host rock. Gold recovery methods for these two types of deposits vary greatly from simple panning to a complex network of grinding, chemical leaching, gravity concentration and more.

For example, one miner improved his recovery from 40% to 70% simply by screening his feed from 8mm to 2mm. No gold was lost, because his largest gold was around .5mm. The iCON method will improve your process by screening your feed to the proper size. This will reduce the volume of feed and increase the percentage of gold that you recover.

The melting point of gold is 1063 ˚C, which is a higher temperature than can be obtained by cheap torches and burners. By adding borax to the heavy mineral concentrate, the melting point temperature decreases, allowing people to melt gold out of their concentrate and salvage. By using borax, no mercury flour is produced, and gold recovery
