The measurements were performed with the use of the inclinometric method consisting of continuous registration of changes in the angle of inclination …
2 Recovery of Copper by Solution Mining Methods Solution mining replicates the natural process of oxidation and reduction, described above. Dilute acidic solutions are introduced to the copper-bearing ores, causing dissolution of soluble copper minerals (Table 1) remaining in the leached cap and underlying enrichment blanket.
Bart Blanpain, in Treatise on Process Metallurgy: Industrial Processes, 2014. 2.1.1.3.1 Dead Roasting and Reduction. In this path, copper minerals are oxidized in the solid state to produce Cu 2 O and Fe 2 O 3. Cu 2 O is then reduced to molten Cu, typically in a blast furnace charged with coke. Flux is also added to form a molten slag in which ...
