sag mill single stage copper mine

Power-based modelling of single-stage AG and SAG mill circuits

Operating data from the single stage SAG mill at Anglo American’s El Soldado mine in Chile was evaluated and compared to four published power-based comminution models. Case studies from literature for other single stage SAG or AG mills were then evaluated in the same four models. Power-based comminution models are used to predict the specific energy consumption (CEE) of a

Autogenous and Semi-Autogenous Mills FLSmidth

Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW. Our team of product engineers continually improves SAG/AG Mill

07/04/2020· Crushed product from the primary crushers, which has a typical P80 of 100 mm, is ground using a single-stage closed grinding circuit with cyclone classification. This comprises a single stage SAG mill, 8.53 m diameter x 4.72 m long, with a rated capacity of 5,800 kW. Cyclone underflow is returned to the SAG mill and the overflow gravitates to the flotation circuit passing via an “in-stream

Gibraltar Copper-Molybdenum Project Mining

“The 109km Gibraltar copper-molybdenum open pit mine is the second-largest copper mine in Canada.” Phase one of the $300m expansion was completed in 2008 at an investment of $76m. It involved installation of a new 34ft semi-autogenous grinding (SAG) mill, replacement of the original flotation recovery system and several downstream upgrades. In the phase two, the concentrator was modified

SINGLE STAGE SAG/AG MILLING DESIGN Metallurgy

capacity is too high for a single SAG mill, a two stage grinding or alternate circuit is generally recommended. 4 Single Stage Configuration Selection The third step in designing a single stage circuit is the selection of the optimum circuit configuration. Single stage AG and SAG circuits can be sub-divided into a number of configurations, each suited to ores with certain characteristics and

Major Mines & Projects Pyhasalmi Mine

After single-stage primary crushing in the underground jaw crusher, the ore is hoisted to the screening plant, which is of the vertical type. There is also a jaw crusher for oversize boulders but in practice, little more than screening is done at the screening plant. After screening, the ore is wet ground in three stages: one primary SAG mill, three secondary SAG mills and one tertiary ball

Optimizing your SAG mill operation International Mining

Single stage AG/SAG mills have to handle large amounts of slurry as they are generally in closed circuit with classifiers whose circulating loads reach as high as 400-500%. The geometry of radial and curved pulp lifters is such that the slurry, once passed through the grate into the pulp lifter, will always be in contact with the grate until it is completely discharged, which makes the ‘flow

Project Summary Taseko Mines Limited

The initial phase included the construction of a 34 foot semi-autogenous grinding (SAG) mill, conversion of rod mills to ball mills and the complete replacement of the flotation recovery system with 160m3 float cells, along with the addition of new mining equipment. Once completed in 2008, these modifications and new equipment increased the processing rate of the concentrator to 46,000 tons

Jervois Copper Project, Northern Territory, Australia

The process plant will comprise a single-stage crushing circuit along with a conventional SAG mill grinding circuit, and a smaller regrind mill. The feed will be passed through the roughing, cleaning, and re-cleaning stages in the flotation circuit. Tailings will be thickened before being pumped to the tailings storage facility (TSF). A filter
