Here is the flowchart for Uganda client.
The mill circuit consists of 1300, 875 and 500 kW ball mills. Classification of leach feed product is handled by 15 inch cyclones. Free gold particles in the cyclone underflow are separated in a concentrator and sent to the gold room for direct smelting, while the remaining underflow goes back to the grinding circuit to be further reduced.
The 12mm ore is then fed into the 600 tonne Mill Bin which feeds the two (of the three installed) 1.8 x 3.6 m rod mills where it is milled down to approximately 70 passing 75 microns, before being passed through two 30 inch continuous Knelson Concentrators where approximately 49 of total gold production is.

The plant is designed to treat an ore throughput of 800,000 tpa. The grinding and wet plant circuits are designed to process ore at a treatment rate of 95.5 tph. Ore is processed through a three stage crushing circuit. Crusher ore is stored in a fine ore bin with a live capacity of 3,000 tonnes. The grinding circuit consists of a single ball mill.
In 2017, a secondary crushing circuit was installed to remove the SAG mill throughput bottleneck and increase production of highly competent underground ore from 1.35 to a minimum of 1.7 Mt a. This paper discusses the findings from the trial phase, the circuit design, project delivery, site optimisation, and the plant performance.
MINING. Mining operations at Kumtor are carried out using conventional open pit mining methods. The Central deposit is mined in a large open pit where total material mined in 2010 was approximately 116 million tonnes, or 318,000 tonnes per day. The overall waste to ore.
Run of mine material is fed to the crushing plant at a design rate of 60 tph with crushed ore storage capacity installed to provide a physical break between crushing and milling operations. Ore is passed through a two stage crushing circuit. Crushed ore is stored in a fine ore.
