12.3 Primary Copper Smelting - US EPA

Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper. A continuous process called floatation, which uses water, various flotation chemicals, and compressed air, separates the ore into fractions.

Understanding the mechanism of microcrack-enhanced bioleaching of copper

2023.4.1 Microcrack generation is the incidental phenomenon during the mineral crushing process, which means extra procedures are not needed (Ghorbani et al., 2013a; Kodali et al., 2011). Moreover, microcracks can promote the exposure of reactive surfaces for chemical attack by the leaching solution, contributing to enhanced bioleaching kinetics.
