From Ore to Finished Product
Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

Study on Beneficiation Technology for Rational Utilization …
Useful minerals were finely distributed in ores. Based on the properties of ore, a beneficiation process of one stage grinding → copper/nickel mixed flotation → copper/nickel separation was proposed. A copper concentrate with a Cu grade of 17.08 wt.% and a nickel concentrate with a Ni grade of 4.63 wt.% were obtained by separation.

New technology makes copper production more sustainable
According to start-up company Jetty Resource, 70% of the world's copper resources – estimated to be worth more than $20 trillion – are tied up in primary sulfide ores. The majority of this ore is too low-grade to justify traditional processing, and the alternative low-cost method of leaching does not work well on primary sulfides, despite decades of industry efforts.
