The Gold Lab Mine For Gold

The Gold Lab – Gold Recovery System. In repeated demonstrations The Gold Lab is able to recover of the gold from test samples. The many hours of testing and tweaking that went into The Gold Lab long before it went into production have resulted in a fail safe gold recovery system.

Leaching of a gold bearing partially roasted sulphide

In the partially roasted sulphides bearing ore, gold was observed by microscopy as particles whose size was in the 10 to 100 mm range, either as completely free or still inserted in grains containing sulphur and arsenium. Most of these grains still contain a few altered core that is bounded by a very porous surface resulting from both the

202055&ensp·&enspGold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, the CIL process lowers the gold mining operation cost and increase the gold recovery rate to a degree of 99%.

Ore characterization, process mineralogy and lab

With the growing size of new and expanded concentrators (150,000–250,000 t), the process risks can be substantially reduced through automated mineralogical lab technology. For example routine daily XRD/NIR analysis can optimize blast indexing, crusher operations, reduce mill performance and/or avoid major flotation problems.
