Copper is expensive to mine and refine. 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.
Nov 25, 2019 The worlds 20 largest copper mines produce nearly 9 million metric tons of the precious metal a year, about 40% of the worlds total copper mine capacity. Chile and Peru, alone, account for more than half of the copper mines on this list. The U.S. makes the cut, as well, with two mines among the top 20. Copper is expensive to mine and refine.
Processes copper mining and production. Copper is found in natural ore deposits around the world.

This ball mill is typically designed to grind mineral ores and other materials with different hardness, and it is widely used in different fields, such as ore dressing, building material field, chemical industry, etc. Due to the difference of its slurry discharging method, it is divided to two types grid type ball mill and overflow type ball mill.
1.1. Types of Copper and Properties. The copper most commonly used for sheet and strip applications complies with ASTM B370. It consists of 99.9 percent copper, and is available in six tempers designated by ASTM B370 as 060 (soft), H00 (cold rolled), H01 (cold rolled, high yield), H02 (half hard), H03 (three quarter hard), and H04 (hard).
Mining Methods 9 The Highland Valley Copper mine, located in British Columbia, 60 km southwest of Kamloops is 97.5% owned by Teck Cominco. Operations at Highland Valley began over 20 years ago by predecessor companies. The present operation is a combination of the Lornex mine and mill, the Valley Copper orebody and the Highmont mine and mill.
Blister copper - A crude form of copper (assaying about 99%) produced in a smelter, which requires further refining before being used for industrial purposes. Block caving - An inexpensive method of mining in which large blocks of ore are undercut, causing the ore to break or cave under its own weight. Board lot - One hundred shares.
High conductivity copper is very readily worked, both hot and cold. It has excellent ductility, which means that it can be easily drawn to fine wire sizes, and it is available in all other fabricated forms. ETP copper contains a minimum of 99.90% copper, with

The open-pit mine is owned and operated by Kansanshi Mining (KMP), a joint venture between First Quantum Minerals (80%) and the Zambia Consolidated Copper Mines-Investment Holdings (ZCCM-IH, 20%).
the mine site, followed by additional crushing at the mill. The crushed ore is mixed with water and initial flotation reagents to form slurry. The ore is then ground in rod and ball mills. The slurry may also be ground in autogenous mills (a mill where the ore acts as the grinding medium) or semi-autogenous mills (steel balls are added to the ore).
