The plant included single stage crushing, with conveyors that deliver the ore to a coarse ore bin. 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.

mill work index 11.4 kWh/t and an average RQD of 44%. RQD values of 25% resulted in a SAG mill feed size (F80) between 55 and 60 mm and throughputs of 6200 t/h. RQD values of 55% resulted in SAG mill feed size (F80) of over 70 mm and a SAG mill throughput of 5200 t/h. The Batu Hijau SAG mill specific energy was a function of point load test and ...
The company has confirmed that by increasing the size and power of both the SAG and ball mills to the levels being supplied by Outotec the throughput rate while feeding higher grade fresh (hard) ore can be increased to maintain a minimum feed rate of 250 t/h (2 Mt/y), up from 200 t/h (1.6 Mt/y) detailed in .
Dacian Gold's ‐owned Mount Morgans gold project, located 25km southwest of Laverton in Western Australia, continues to meet its key targets, with the treatment plant now 50% built Arrival of the two halves of the 8.5m diameter, 3.5m long SAG mill to the Mt Morgans site
The project comprises the Silver Swan underground mine, the Black Swan open pit and the Black Swan 2.2Mtpa Concentrator with 191,400t of nickel metal in resource. Black Swan has been on care and maintenance since 2009 following the global downturn. The Black Swan tenements, mines, plant and equipment remain in good standing.
Oct 12, 2017· SAG mill make use of steel balls included with some large and hard rocks for grinding. These mills utilize the balls in making the large fragments of materials broken into pieces. The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is filled with balls partially.

The SMC Test® is the most widely-used comminution test in the world for AG & SAG Mills, HPGRs and Crushers. It is used to design comminution plants, optimize circuit performance, forecast throughput, reduce CO 2 emissions and cut energy costs.
Project Overview: The Century Zinc SAG mill has been the subject of two major advanced control projects since its commissioning in 1999. Over time, both systems failed to meet the mill's needs and operating staff lost confidence, preferring to operate the mill semi-automatically.
Plant throughput is constrained primarily by ore competency. The DFS called for the use of a single gearless SAG mill with 21,500 kW of installed power (at the time of t hestudy this was the highest power available for a gearless drive Constancia'sat altitude) and two ball mills .

Frozen charge detection and automatic loosening with gearless mill drives (SAG Conf. 2015) Mill drives: the desire for increased power and the associated limits and conditions (SAG Conf. 2015) ... contributing to the outstanding plant availability of around 95%.
The three gearless mill drive (GMD) systems are the ABB most powerful ever made. The GMD for the 40-foot SAG mill has a power rating of 28 megawatts (MW), and the GMDs for the two 28-foot ball mills have a power rating of 22 MW. They are the largest diameter and most powerful SAG and ball mills drive systems at the highest altitude installed to ...
The project was executed in two phases. The first phase involved the installation, commissioning ... SAG mill weight stability and preventing of over filling of the mill ... protecting the SAG mill and increasing liner system life. Plant' reports indicate that the liner life was extended by three months as a direct
SAG Mill, Ball Mill, and Flotation. Gangue collects at the bottom of the flotation cell and ultimately ends up as waste known as tailings. Tailings are channeled to a natural disposal system flowing from the Mill to the Modified Ajkwa Deposition Area (ModADA).
ABB provides complete electrification and automation solutions for the Aktogay copper plant under a contract awarded in December 2012. ABB was also awarded a $44m contract in May 2012 to provide three gearless mill drive systems, including the 28MW semi-SAG mill and two 22MW ball mills.
