The IE of the V-bso modified oxidized copper is higher than that of the V-bso modified copper and the oxidized copper layer, just because the former has two layers. The results of the interface capacitance show that the self-assemble films of the V-bso on the oxidized copper surface have good potential stability.

· Porphyry copper deposits account for more than 80% of the world's total Cu resources. However, the formation mechanism and controlling factors of porphyry copper deposits remain obscure. Previous studies have revealed that porphyry copper deposits are usually associated with oxidized, calc-alkalic, adakitic shallow intrusive rocks.

· Copper may be either supplied directly by the oxidized magmatic fluids or released by resorption of immiscible magmatic sulfides in the reduced melt in which it may be of crustal origin. However, where mafic magma and associated fluid recharge of the silicic chambers does not take place, Cu-poor Sn deposits are the likely outcome.
· Copper oxalates identification: (a) PXRD pattern (Rigaku PDXL 2.0) of moolooite from L. inops on ore from the Voronov Bor deposit; (b) PXRD pattern (Rigaku PDXL 2.0) of moolooite formed in model ...
· ore flux m The Egyptian copper smelting furnace was filled with a mixture of copper ore, charcoal and iron ore to act as a flux. It was blown for several hours by foot or hand bellows. By the end of the smelt the copper had separated from the slag, which was tapped off.
flotation process of the oxidized copper ore the prelimi-nary sulfidization by a modified sulfidizing reagent. Referring to this model it is possible to recommend the optimal conditions for flotation: 50 % of MSR in rela-tion to the oxidized copper containing in floated ore, 4 min of agitation of pulp with MSR and 200 g/t of a col-lecting agent.
Copper is recovered from an aqueous pulp of an ore containing both sulfide minerals and oxidized minerals by continuously monitoring the EMF of the pulp and adding a water-soluble sulfide to the pulp in an amount from 0.05 to 7 pounds of contained sulfur per ton of ore whenever and for so long as the pump EMF is above about -30 millivolts with reference to a standard silver-silver …

· Gold leaching of oxidized copper refractory ore (Tarror mineral deposit) demonstrated low gold recovery by direct cyanidation. The reason was the high copper content present because it forms stable copper-cyanic complexes. Application of ammonium compounds to oxidized ores provides high rates of gold recovery and prevents the formation of copper
In this study, the flotation of oxidized copper ore obtained from Ergani Copper Mining Company in Turkey was performed. This ore contains 2.03% copper, 0.15% cobalt and 3.73% sulfur.
