Originally the mine started operating for gold extraction in 1984 however 3 years later the operation diversified into copper production. Gold production ceased in 1988. World wide Ok Tedi is one of the largest copper mine, with a total ore reserve in 1996 of over 400 million tonnes.

The Ok Tedi copper and gold mine in Papua New Guinea has discharged more than two billion metric tons of tailings, overburden, and waste rock into the Fly River system since the mid 1980s, polluting the river corridor from the mine to the sea, a distance of one thousand kilometers (Tingay 2007, 5).

Gold Extraction Process The mechanical and chemical gold extraction process used at Charters Towers has evolved to become a highly sophisticated, technical process. Today, modern processing plants commonly practice a chemical extraction method, whereby carbon is used to recover gold.
The Mining Process. 1. Mining open pit and underground. this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.
The gold room uses the Anglo American Research Laboratories stripping system to strip gold from loaded carbon in batches of approximately 1.9 tonnes. The process is fully automated and controlled by electronic sequence controllers which switch both pumps and valves for each step.

Of all the methods of extracting gold amp; processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration.
However, extraction of gold also has different gold leaching methods, but generally, it uses gold leaching methods such as gold ore gravity separation, gold ore magnetic separation, gold ore flotation separation, gold ore amalgamation, gold ore cyaniding and the latest resin pulp separation, carbon paste adsorption as well as dump leaching.
After gold is extracted, wastewater or process solutions may contain three principle types of cyanide compounds free cyanide, weakly complexed cyanide and strongly complexed cyanide (WHO ECEH, 2000). Gold and cyanide can form a strong complex in relatively weak cyanide solutions.
Carbon samples loaded with gold over this general range all responded similarly to the desorption process. Residual gold levels on the desorbed carbon can easily be held to well less than one ounce per ton. Ok Tedi Mining Limited Elution process and apparatus and extraction of particulate material from a vessel Elution process and
