LEACHING OF LOW-GRADE COPPER ORES: A CASE

2017-6-9  Figure 3b shows similar behaviour like during the leaching process of the ore from cementation zone of the ore body. Obtained kinetic curves of the leaching confirm that, but the copper concentration in the solution was half in the case of the transition zone (~0.80 g dm-3 Cu), which is due to mineralogical composition of the ore (lower copper content in the form of oxide minerals). The
