Grinding and flotation, one system
Products
Grinding Media & Flotation Chemicals
Auday supplies two product families: grinding media and flotation chemicals. How we choose and adjust them for your operation is described under Solutions.
Forged Grinding Media
Forged steel balls for high-impact and general grinding duties, from large SAG top-up sizes down to regrind.
High Chrome Grinding Media
Cast high-chromium balls for abrasive grinding in ball and stirred mills, where wear resistance matters more than impact strength.
Ceramic Grinding Media
Ceramic beads for fine and ultrafine grinding in stirred mills.
Flotation Chemicals
Collectors, frothers, depressants, modifiers and specialised blends for flotation circuits.
Grinding Media Product Range
Three media families, from primary to fine grinding
Forged, high chrome and ceramic media for SAG, ball, regrind and stirred mills
Typical applications are listed for each, but the right media depends on the ore, the mill and the grinding duty, so selection is made per application.
Flotation Chemicals
Flotation chemicals, selected for the cause of the problem
Collectors, frothers, depressants, modifiers and specialised blends for flotation circuits.
- Collectors
- Frothers
- Depressants
- Modifiers
- Specialised blends
Choosing media or reagents for a specific circuit?
Grinding optimisation: we test media size, chemistry and hardness against your ore, mill and operating data, then prove the result on site.
Flotation optimisation: we diagnose the limitation first, then design the chemistry and operating strategy around it.
