a mining attempt in the 1911 - 1924 period recorded an output of 2,450 ounces of gold and mining and processing of a 44,000 tonne bulk sample in 1988 produced 7,300 ounces of gold. the average recovered grade of this mineralization was 6.51 g au/t and it was noted that recoveries in both tests
after the leaching process is complete, the soluble gold must be concentrated and separated from the process slurry. the method of recovery of gold from the process slurry is by carbon adsorption. adsorption is a term used to describe the attraction of a mineral compound to the surface of

the first process that most of the ores or minerals undergo after they leave any mine, is mineral processing or mineral/ ore dressing. it is a process of ore preparation, milling, and ore dressing
mineral that reported to the tailings is gold. the results in table 4 indicate a gold grade of 0.11%. the foregoing indicate that beneficiation by shaking table resulted in gold enrichment of 3.744 at a particle size of -710μm +500μm [table 4] while lead enrichment in the concentrates was 2.051 [table 3]. thus a
