The Process Flowsheet CCD CY-1 shows (below) the continuous counter-current decantation system, in which all the ore is first reduced to a very fine state in the grinding mill-classifier circuit, in a cyanide solution.The slime overflow of the classifier, usually 70%—200 mesh, or finer, is sent to the first thickener, known as the primary thickener.
The operations in Queensland state include the Osborne copper gold processing plant, Mount Elliot mine, infrastructure including an airport, roads and a power plant and a number of development sites.
CIL (Carbon In Leach), the gold carbon leaching method, is the carbon leaching method for gold extraction.Normally, the CIL process can concentrate gold from 2.5–3.5 g/t in ore to 2000 to 6000 g/t in carbon. The CIL gold process is suitable for beneficiating oxidized gold ore with low sulfur and mud content; Or process the gold tailings after gravity separation and mercury mixing.

Using a gold wash plant, exposed gold-bearing gravels are mined using a bulldozer that pushes and stockpiles the gravel near a wash plant.The stockpiled gold-bearing gravel is then fed into the wash plant by a front-end loader or large backhoe. This practice promotes equipment efficiency by allowing the bulldozer to continue mining while the loader or backhoe feeds the …

Gold processing equipment example. The discharge from the Unit Cell is higher than the feed inlet, thus making it possible to place the Unit Cell in the ball mill-classifier circuit without an elevator or pump. Still another important unit in these cyanide circuits is the "Spiral Rake" Thickener with the beam type, lowhead superstructure.
In this process sodium cyanide, in a dilute solution of ranging from 100 ppm to 500 ppm or 0.01% to 0.05% cyanide, is used to selectively dissolve gold from ore. The two most common processes that use cyanide for gold recovery are heap leaching and milling, also known as carbon-in-leach (CIL).
