Early in 2018, they started planning a $200 million capital expansion of Bagdad's ore-concentrating mill that would lift production by 20 percent. Copper prices were high at the time. The investment looked certain to pay off. Then copper prices dropped from a five-year peak of around $3.30 per pound in early June to $2.75 or so a month later.

The copper mining industry faces challenges associated with deposits, scarcity of resources, and pressure to reduce environmental impacts. One of the problems associated with the ores corresponds to the low grades of the deposits and their mineralogical associations, such as pyrite and clay, which reduce the value of the concentrate.

Copper was first mined in this area by an ancient vanished race between 5,000 and 1,200 bc. These miners left no burial grounds, dwellings, pottery, clay tablets or cave drawings. What was left behind was thousands of copper producing pits and more thousands of crude hammering stones with which the pits had been worked.

Copper processing begins with mining copper ore, which contains less than 1% of copper, and ends with sheets of 99.99% pure copper (cathodes). Copper mining generally takes place through open-pit mining, in which a series of stepped benches are dug deeper into the earth. Yet, it can also be mined underground, through horizontal tunnels.

By using ore sorting equipment, ore concentrates can be created at very low cost in small or remote mining installations. The entire processing line can be planned in semi-mobile form and consists only of crushers, screens, belts and sorting machines. This allows immense cost savings for transport, since the waste rock is disposed of on-site.
