a 700 kw higmill for a copper concentrate regrind application at the kevitsa mine in finland has been commissioned in february 2015 and is operating successfully; both the copper recovery and the copper grade in the final copper concentrate have been increased significantly, where at the same time the nickel grade in the final copper concentrate …
Grinding in these units is completely by abrasion, producing ultrafine particles. MIM's first experience with the tower mill was in the Hilton concentrator in the low-grade middling (LGM) circuit, which is fed from both the lead and zinc flotation circuits. This feed is ground in closed-circuit in the tower mill to 80% minus-25-micron.
Since the grinding principle of multi-compartment grinding offers substantial energy savings, a new stirred mill has been developed for coarse grinding applications up to 6 mm feed size, the Vertical Power Mill™ (VPM). Mill sizes range from 700 kW to 12,500 kW with high flow rates, and potential energy savings of up to 40%.
Also known as ROM or "Run Of Mine" grinding. SAG mill. SAG is an acronym for Semi-Autogenous Grinding. SAG mills are essentially autogenous mills, but utilize grinding balls to aid in grinding like in a ball mill. A SAG mill is generally used as a primary or first stage grinding solution. The SAG mills use a minimal ball charge of 6 to 15%.

The Capricorn Copper processing plant is a conventional flow sheet involving crushing, grinding, screening and flotation to produce mineral concentrates. Screening: - SAG mill discharge is screened via trommel, with oversize material recycled back to the SAG mill for further grinding via a series of scats conveyors.
This high intensity grinding technology (>300kW/mm3) requires a much smaller footprint than conventional grinding technology – the grinding volume of the IsaMill™ is about one tenth the equivalent ball or tower mill.

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
