This included the sites and of the old Minesota, Superior and Rockland mines.
associated with copper extraction were the primary feature of study. However, the expanded research outside Arizona did detect a number of gold mill tailings impoundments as well, likely because copper and gold mill tailings are similar in physical composition and are shown to have an overlap in sediment grain size (Qiu and Sego, 2001).
· Copper Ore Processing Methods. The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining.

· Primary mills consist of three semi-autogenous (SAG) mills and two autogenous (AG) mills. The SAG mills are comprised of two 9.75 metre diameter by 4.72 metre long fixed speed mills and one 10.36 metre diameter by 4.88 metre long variable speed mill. Each primary grinding line is supported by two secondary ball mills at 5.03 metres in diameter.
The dried copper concentrate of about 28 percent copper is shipped to the smelter. It represents less than one percent of the material removed from the mine. Concentrate is just a fine powder of the mineral chalcopyrite which is a naturally occurring compound of copper, iron, and sulfur.
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 ().
