Mill throughput is a key driver for maintaining profitability at Mt Keith because of the low head grade (~0.5% Ni) and inherently low nickel recoveries due to the mineralogical makeup of the ore. The Nickel West Mt Keith Concentrator (NMK) has 2 parallel grinding modules consisting of one SAG Mill and one BALL Mill per module.

DRA has been engaged by BHP Nickel West to provide detailed engineering and design services to support the expansion of the crushing and grinding circuit at their Mt Keith operation, including new stockpile feed conveyors, coarse ore stockpile, reclaim conveyor, 16MW SAG Mill grinding circuit and an 11kV substation.
The resultant flowsheet consisted of primary crushing using a sizer, a scrubber with minimal power input to remove the limonite, followed by high ball charge SAG milling to grind the saprolite. A third saprolite source was treated in a single stage SAG mill. Together, three products were to be produced from the grinding circuit. Outcome
3.2.1 Primary FAG/SAG Mill Circuit Ore is withdrawn from the conical stockpile via 2 of 4 apron feeders and delivered to the primary mill feed conveyor. A semi-automatic ball loading system is available to load steel balls onto the mill feed conveyor. The fresh feed ore size detection is done via a Lynxx optical size analyser.

Outotec says it has signed an agreement to deliver its "industry-leading comminution equipment" to Norilsk Nickel's refurbishment project at the Talnakh processing plant in Norilsk, Russia. The contract includes delivery of one SAG mill and two ball mills with a total installed power of 36 MW, as well as two HP series pebble crushers.
SAG and AG Mills operate by lifting ore/grinding media and dropping it on the operating bed of the mill charge. High impacts from lifting ore and media promote impact breakage which is the primary mechanism for size reduction in the mill. Via the use of sophisticated instruments and software, we closely monitor the mill impact location to boost ...

The crushed ore will be ground in a semi-autogenous (SAG) mill and a ball mill before undergoing rougher and cleaner flotation processes for the production of concentrate grading up to 30% nickel. The obtained concentrate will be thickened and filtered in a dedicated concentrate handling facility.
The Mount Keith (Mt Keith) nickel mine is a large-scale, low-grade sulphide ore open-pit operation located in Western Australia. BHP Billiton owns and operates the Mt Keith mine and concentrator as part of its mine-to-market integrated nickel business Nickel West, which also includes the Cliffs and Leinster underground mines, and the Leinster and Kambalda …
Mined ore is hauled to two primary crushers at an average rate of 1300 t/h. The primary crushing stage product is conveyed to a 67 kt capacity stockpile. Reclaimed ore is conveyed at 860 t/h to the grinding circuit, which includes one SAG mill, two pebble crushers and two ball mills.
The SAG mill agreement has come about as First Majestic ordered a complete new SAG mill package, which, Condor says, is now superfluous to its requirements. The SAG mill has a mill diameter of 24 ft (7.3 m) and an effective grinding length of 18.5 ft and a structural charge mass of 315 t, Condor Gold said.
The inside of the mill is lined with lifting plates to lift the material inside the mill, where it then falls off the plates onto the rest of the ore charge. SAG mills are primarily used at gold, copper and platinum mines with applications also in the lead, zinc, silver, alumina and …
Ore is recovered from the crushed ore stockpile by four apron feeders (per mill) located in a tunnel underneath the stockpile. Milling, pebble crushing The mills were selected on the basis of two milling trains, each comprising the largest SAG and ball mills currently proven at other operations, at the time of design.
Savannah ore has been successfully treated through SAG mill since commissioning in 2004. Subsequent to the restart further works were completed including the replacement of the Jaw crusher and SAG mill motor. A full set of filters plates is onsite ready for installation.

In mineral processing or metallurgy, the first stage of comminution is crushing.. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.
The SAG mill was designed to treat 2,065 t h −1 of ore at a ball charge of 8% volume, total filling of 25% volume, and an operating mill speed of 74% of critical. The mill is fitted with 80 mm grates with total grate open area of 7.66 m 2 (Hart et al., 2001).
Coarse ore is ground in a two stage grinding circuit that comprises a SAG and ball mill. The ore/slurry from the grinding circuit is classified via the mill cyclones and the cyclone overflow undergoes differential flotation. The nickel and copper flotation circuits have dedicated regrind, cleaning and re-cleaning processes to optimise metal ...
