circuit rod mill at a rate of 24 tph. From the rod mill the discharge combines with the 16'x12' regrind. mill product and is pumped to two 30" CD-Knelson concentrators. that are connected in parallel. Knelson Concentrates are further. treated on the Gemini table to produce a much cleaner concentrate which is calcined before smelting on site.

Yes, there is no ball mills in that grinding circuit. The p80 to the SAG mill was at about 6" while its product (flotation feed) was at 40 microns. So the answer to your question is yes, a SAG mill can be installed in an operation milling 2,000 tpd and it can be operated efficiently if the operators have the knowledge to operate it well.

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 recovered.
Classification for each ball mill line was provided by a cluster or 5-10" diameter cyclones, with Knelson concentrators treating a bleed stream from the cyclone underflow that was being fed to each ball mill. Gemini tables in each grinding line were used to clean the Knelson gravity concentrates. The primary cyclone overflows were then ...

A Knelson concentrator gravity recovery circuit treats the entire ball mill discharge for coarse, free gold recovery. The Knelson concentrate is processed in an intensive leach reactor (ILR). ILR leach solution is treated by direct electrowinning. The cyclone overflow stream flows by gravity to a linear trash screen ahead of a pre-leach thickener.

Deya machinery is the main manufacturer of centrifugal concentrator in China, in the concentrator it has a ribbed rotating cone into which the pulp of 20 to 40% solids is fed and the concentrate is accumulated in the riffles. Compaction of the concentrate layer is avoided by injection of water in counter flow.
A two-stage PGPGM procedure is introduced using a standard Knelson Concentrator (KC-MD3) followed by variable speed KC-MD3 operated at higher bowl speed. This combination proved successful in recovering the fine liberated PGMs. The GRPGM was about 80% on the ball mill-cyclone circulating load, similar to that determined for the ore.
A Knelson concentrator is a type of gravity concentration apparatus, predominantly used in the gold mining industry. It is used for the recovery of fine particles of free gold, meaning gold that does not require gold cyanidation for recovery.
