Mill (grinding) - WikipediaA 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 (e.g., via a hand crank),.milling mining nickel,Mining 101 – Eagle MineConventional crushing, grinding, floatation, and pressing are used to process run-of-mine ore into separate nickel and copper concentrates. Road haul trucks arrive at the mill and dump their load in the enclosed Coarse Ore Storage Area. Each truckload weighs on average between 40-45 tonnes. Ore will go through three.

Baden, Switzerland, February 6, 2014 – ABB, the leading power and automation technology group, has commissioned an upgrade to Vale's existing Clarabelle dual pinion semi-autogenous (SAG) mill. The mill is used to reduce the size of the ore at the company's nickel and copper mines in the Sudbury area, Ontario.
process called froth flotation. When air bubbles are introduced to the slurry, the minerals attach to the bubbles and float to the surface, where they are skimmed off. Both the nickel and copper float off together, and then the nickel is separated from the copper. The results of this are two distinct products: a nickel concentrate.
