problems in heap leaching of copper ore
While heap leaching for copper was under discussion in the 1920s, he said, leaching of residual material in old stopes began in 1923 at Bisbee, Arizona, USA. This was followed by the in-situ leaching of ore left over from block caving at several mines, including Ray and Miami; in the late 1950s, Miami created a block-cave stope specifically for

ORE GEO-TECHNICAL EFFECTS ON COPPER HEAP LEACH KINETICS
The geotechnical characteristics of the ore are important in understanding the kinetics of copper heap leaching. These characteristics can indicate potential problems and can be used to determine the semi-quantitative changes in field kinetics as compared with column kinetics.

OVERVIEW OF GANGUE MINERALOGY ISSUES IN OXIDE COPPER …
Copper heap leaching projects are sometimes evaluated without adequate attention to mineralogy, despite the fact that ore and gangue mineralogy is probably the single most important parameter affecting operating costs and recoveries and can change significantly from one area of the resource to another. A wide range of mineralogy issues needs to be considered in maximizing the efficiency of ...

Heap leaching - Wikipedia
The mined ore is usually crushed into small chunks and heaped on an impermeable stone or clay lined leach pad where it can be irrigated with a leach solution to dissolve the valuable metals. While sprinklers are occasionally used for irrigation, more often operations use drip irrigation to minimize evaporation, provide more uniform distribution of the leach solution, and avoid damaging the exposed mineral. The solution then percolates through the heap and leaches both the target and other minerals. This process, called the "leach cycle," generally takes from one or two months for simple oxide ores (e.g. mo…
