Heap Leach In Sudan

Ariab

AMC was the first mining company to use the Heap Leach technique in Sudan. As heap leach is one of the conventional processes, AMC has developed a strong measure to ensure the efficiency and cost effectiveness of the process. HSSE has been well considered to mitigate any leakage of the heap leach solutions outside the process channels.

RE-PROCESSING OF GOLD TAILINGS AT ARIAB AREA NORTH-

The main objective of this research is to extract the Gold from the tailings which are dumped at Ariab Mines North East of Sudan by using the processing technology. These tailings dumps amount about 2,500,000 ton and contain Gold between (1.1-1.4)g/t, A bulk sample about 700kg from heap No 102 was used to conduct this study.
