S Nadolski, R Haycock, K Li, S Seiler, A Kumar SAG Conference Vancouver, Canada September 22 – 26, 2019 ABSTRACT A comprehensive energy study was carried out for the Red Chris mill, which processes copper-gold ore at a rate of 30,000 tonnes per day (t/d) and is .
• 12.8 Mt/a of copper-gold bearing ore from the open pit • Plant Feed Grades are 0.75% Cu and 0.33g/t of Au and 3.8g/t of Ag • Concentrate quality is +25% Cu, 7 g/t of Au and 60g/t of Ag • Primary Grinding Circuit contains – 34 ft × 18 ft (13MW) SAG mill – 24 ft × 39 ft (13 MW) ball mill • Regrinding Circuit .
In the first three years of continuous operation, Vale investigated different alternatives for improving the circuit’s performance by investigating operating conditions, mainly focusing on the SAG mill. It was decided to further assess the performance of the comminution circuit as a function of ore .
Sossego was the first Vale SAG mill operation to process copper-gold ore. It is located in the State of Para, southeastern Amazon region of Brazil. In the first three years of continuous operation, Vale investigated different alternatives for improving the circuit`s performance by investigating operating conditions, mainly focusing on the SAG mill.
SAG Mill Grinding Circuit Design. The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account.

SAG/ball mill (gravity gold recovery in ball mill circuit), cyanidation and CIL Ore throughput progressively increased by ~300% from plant design: 4.8Mtpa to 12.0 Mtpa over first 5 years; seven open pits – blend of soft and hard ores; saprolitic Single CIL circuit (design) split into 2 parallel circuits .
mill gold ore processing - discobol. Gold is usually found alone or alloyed with mercury or silver, but can also be found in ores such as calaverite, sylvanite, nagyagite, petzite and krennerite. Most gold ore now comes from either open pit or underground mines. The ores sometimes contain as little as 5/100 of an ounce of gold .
SAG Mill Grinding Circuit Design - Mineral Processing ...
Two separate carbon-in-leach ("CIL") circuits recover the gold from the re-ground concentrate and from the flotation tails, with final gold recovery accomplished by electrowinning and refining. The mill was originally designed with a capacity to process 4.8 million tonnes of ore per year, but the actual mill throughput in 2011 was ...
The high unit capacity SAG mill/ball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs, which has in turn made many low-grade, high-tonnage operations such as copper and gold ores feasible. Future circuits may see increasing use of high pressure grinding rolls (Rosas et al., 2012).
