Oxide copper mineral deposits contain varying amounts of chrysoeolla, and poor copper recoveries are generally associated with the lack of flotation response from this mineral. Of the treatment methods available, the use of collectors that chemisorb onto the mineral surfaces during flotation would, apparently, overcome most of the difficul

Flotation with fatty acids or surface sulphidisation of copper oxide minerals and their subsequent flotation using sulfhydryl collectors are two main methods for the Cu recovery from oxide ores. The first method is more suitable for the ores containing silicate gangue because the carbonate gangue has a high tendency to float with fatty acids.

ore after sulphidisation showed a copper deportment of 0.1 % cuprite, 0.6 % malachite, 0.8 % chalcopyrite and 84.8 % chrysocolla, suggesting that all oxide copper minerals present in the LQ ore, except chrysocolla, are amenable to flotation using SIBX after sulphidisation. This

The aim of this study was the recovery of copper from the oxide copper ore by froth flotation and agitating sulphuric acid (H 2 SO 4) leaching. The ore with 4.21% copper grade used in this study was obtained from Çorum-Dangaz region of Turkey. Native copper, cuprite (Cu 2 O), tenorite (CuO), and malachite (Cu 2 (OH) 2 /CO 3) were the

The traditional method applied for the flotation of copper oxide or mixed ores is sulphidisation, which was first developed with industrial success on Pb–Zn oxide ores in Australia (Crozier, 1991). The method involves multistage addition of sodium sulphide (Na 2 S), sodium hydrogen sulphide (NaHS), or ammonium sulphide (NH 4) 2
