Mill (grinding) - Wikipedia

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 (e.g., via a hand crank), working animal (e.g., horse mill), wind or water (). In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill & ball mills, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.

 · The mighty Plumbago Mine (aka lower Plumbago) and Stamp Mill has a long and rich history. Millions of dollars of high grade have been pulled from small pockets throughout intermittent intervals since the 1860s. Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls.

The Mine to Mill methodology was developed during the commodity price downturn of the 1990s and was widely adopted at numerous sites around the world. Mine to Mill relies on the fact that comminution is usually the site processing bottleneck and that blasting is more efficient at breaking rock than grinding. The ore is then delivered to the crusher or the appropriate stockpile depending on the daily blending requirements. Kumtor has an active and dynamic blending program in close contact with the mill that adjusts the ore blend as required to maximize the gold recovery. MILLING

Milling: This process takes place at a mill after the ore containing uranium is removed from the Earth through open pit or underground mining. The ore is brought to a mill, crushed, and ground up before chemicals are added to dissolve the uranium. The uranium is then separated from the chemical solution, solidified, dried and packaged. The ore could only be loaded, however, if it was mined, and it could not be mined if the mine was flooded. This is where the Argo Tunnel was crucial to the success of the mines in “The Richest Square Mile on Earth”, a longstanding nickname for the Quartz Hill area.
