The two Nchanga concentrators (East mill and West mill) were recently modernized. A new concentrator was commissioned at Konkola in 2008. ... Since inception of the mine, refractory ore from the copper production process was surface stockpiled. KCM has now developed a process to extract copper from the refractory ore stockpile.
Inside the ball mill, the crushed copper ore will grind the ore to about 0.2 mm with 3-inch steel balls. This copper ore slurry is finally pumped to the flotation deck. This copper ore slurry is finally pumped to the flotation deck with the fine sulfide ore (~-0.5 mm) going to froth flotation cells for recovery of copper. Commonly Used Machines

In 2020, U.S. mine production of recoverable copper decreased by 5% to an estimated 1.2 million tons and was valued at an estimated $7.5 billion, 3% less than $7.75 billion in 2019. Arizona was the leading copper-producing State and accounted for an estimated 74% of domestic output, followed by, in
Molten copper is molded into a bar at a rate less than ½ a mile per hour and exits the mill close to 72 miles per hour. The bar is rolled through 16 stands and is reduced from a 2.5" x 5" rectangle bar to a 5/16" rod (1/200th of its original size).
The Ball Mill 3 Expansion Project will increase mill throughput to 45,000 tonnes per day from 40,000 tonnes per day and improve copper recovery due to achieving a finer grind of ore. As of the end of the quarter, concrete foundations are complete, structural steel is well advanced, and the mill assembly has commenced.
