Extraction of Gold
Complete extraction of the gold by amalgamation is impossible, a part remaining in the mud of the stamp mills. Concentration is effected by washing, and the " concentrates " are chlorinated by the Plattner process. A further operation divides the waste products into 60 per cent, of " tailings " and 40 per cent, of "slimes," and these materials are further extracted by the cyanideprocess.

How to Extract Gold from Tailing?miningpedia
· Extracting gold from tailings is one of the effective ways for its resource utilization. After roastingcyanidation process, most of the gold in the tailings is embedded in the iron oxide inclusions and silie (quartz) inclusions. Fully open these two inclusions is the first condition to obtain a higher gold extraction rate. Therefore, the methods of extracting gold from cyanide tailings can ...
