Comminution
ALS Metallurgy offers a comprehensive range of crushing andgrinding testwork services:
• Autogenous media competency
• Bond abrasion index • Bond ball mill work index• Bond impact crushing work index • Bond rod mill work index • Comparative work index • High pressure grinding rolls (HPGR) up to 10tph • Inferred work index • JK drop-weight test & SMC test • Levin open circuit grindability • Pilot SABC (AG/SAG) up to 4tph • Point load test • SAGDesign (Starkey) •
Ultra ne grinding – IsaMillTM, Metso Verti-mill, StirredMedia Detritor, Deswik, Metprotech • Unconned compressive strength
Plus extensive crushing, screening, bulk grinding, scrubbingand attritioning capabilities.
Piloting Facilities
For many projects, to reduce the technical and commercial risk,there is no substitute for pilot testing. The best pilot program isbased on thorough bench-scale testing and circuit simulation.We have completed hundreds of pilot plant programmes since
1979.Comminution pilot-plant capabilities at our Australian operationsinclude a permanent pilot AG/SAG milling circuit installation.The mill is one of the few remaining 6’ x 2’ high aspect units inthe world still in operation. This instrumented pilot plant allowscircuit changes to be brought to steady-state more rapidly andavoids wasted pilot plant time.
Circuit congurations, including AG, SAG, ABC or SABC, areevaluated easily.
With an extensive, exible piloting facility, our dedicated pilotplant team can congure a range of continuous circuits, for all
commodities, incorporating: • Bulk crushing, blending & screening • AG/SAG milling • Pebble, ball & rod milling • High pressure grinding rolls • Ultra ne grinding • Hydrocyclones • Hydrometallurgy• Magnetic separation • Dense medium cyclone plant • Gravity separation • Flotation•
Thickening & ltration • Tailings management
And much more!
Extensive
ServicesCrushing of ore is a signicant capital and operating cost in manymineral processing plants. Up to fty percent of the operatingcosts can be attributed to crushing and milling alone.
ALS Metallurgy’s comminution process development testwork, at both laboratory and continuous pilot plant scales,minimises the technical risks associated with the developmentof comminution circuits through well-planned, well-managed,and well-executed metallurgical test work programmes.
It is important to fully determine the comminution parametersrelevant to the crushing and milling of an ore to enable completeplant design to take place with condence. The results from thesetests are used for simulation modelling, scale-up studies andtechnical due diligence.
Trusted by the international mining, engineering and nancialsectors, our specialist comminution metallurgists work with youand your consultants to develop and demonstrate successfulprocessing strategies to support process optimisation, pre-feasibility and feasibility studies.
With industry leading expertise in geochemistry, mineralogy andmetallurgy, the ALS Group can provide you with a wide range of
services including:
Exploration Services
