Copper Sulfide Processingcopper Mineral Processing

leaching of a low-grade, copper-nickel sulfide ore. 1. key,the economic extraction of metals from low-grade ores requires low-cost processing methods such as dump and heap leaching. the most successful heap leaching operations have been those processing copper oxides and secondary copper sulfide minerals such as chalcocite. together with dump leaching of mine waste, heap leaching contributes about.mineralogy of sulfides | elements | geoscienceworld,sulfide surface chemistry is particularly important because of its relevance to the oxidation and breakdown of sulfide minerals and to the processing of mined ores using froth flotation or leaching. investigations using spectroscopic and imaging studies of pristine surfaces in ultra-high vacuum (uhv) conditions have provided information on structure and reactivity at an atomic resolution..
