The finely ground material is treated in two mineral floatation circuits to extract the copper, gold and silver as a copper concentrate. A portion of gold is also separately captured utilising a gravity gold circuit. The concentrate is then piped 156 kilometres south to the Kiunga port facilities located on the Fly River.

The world's gold production has changed over the past 30 years. The exploration and discovery of large, free-milling gold deposits in major mining districts has declined. Mining companies face a difficult decision. Do they process large, low-grade deposits or look for smaller, often more complex ones in remote, often hard-to-reach locations?

The gold beneficiation process is gravity separation, flotation, magnetic separation, cip, cil, heap leaching and other combined methods. Alluvial/Placer gold process: The gold concentrate of placer gold ore has a high content and mostly exists in the form of sand grains. Therefore, gravity separation is often used when sorting. After pretreatment, desliming and washing of ore, …

The structure of the hydrocyclone is relatively simple. Its upper end is a cylindrical part, and its lower part is a conical container. The slurry is fed into the cyclone at a certain speed (generally 5 to 12 meters per second) along the tangential direction, and obtains a rotary motion, thus generating a large centrifugal force (usually tens of times or even hundreds of times greater …

By referring to the tables "Minerals and Their Characteristics" (pages 332-339) it is seen that the perfect grade of a copper concentrate will be 63.3% when the copper is in the form of bornite, 79.8% when in the mineral chalcocite, and 34.6% when in the mineral chalcopyrite. A common association is that of chalcopyrite and galena.
