· In a conventional EW process, it is not possible to use directly the PLS solution from leaching due to the high concentration of copper required (>40 g·dm3). Studies about direct electrochemical recovery of copper from ammonia solutions have been carried out with promising results ( Majima, 1993 ; Bingöl et al., 2005 ; Guo and Searson, 2010 ; Ordoñez and Alfaro, 2011 ; .

Solutions containing ammonia allow for selective leaching of copper from a copper ore. In this study, the leaching and kinetics of malachite ore were examined using ammonium acetate solutions as an alternative lixiviant. The effects of some experimental parameters on the leaching of malachite ore were investigated. A kinetic model to represent the effects of these parameters on the leaching ...
· Thus, ammoniumchlorideammonia system was reported to be a better choice for recoverying zinc from zinc bearing materials (Yang et al. 2019; Xia et al. 2013). However, the volatilization of ammonia during leaching and electrowinning is a serious problem that may cause secondary pollution. Accordingly, the ammoniumchloride solution system ...

In ammonia leaching of oxidized copper ores, as the dissolution reactions happen at mildly acidic or basic conditions, some metal impurities, which pass into the solution during the dissolution of ore, precipitate because of the high pH of the solution. Besides, ammonia forms stable complexes with copper ions, and this can lead to an increase in the dissolution rate of copper from ore. Thus ...
Leaching of copper from tailings using ammonia/ammonium. Aug 03, 2010· Abstract: The leaching of copper from the tailings of Baifang Copper Mine in Hunan province in China by aqueous ammonia/ammonium chloride solutions has been studied The tailings belong to a lowgrade and highalkaline copper ore The effect of leaching time, the concentration of ammonia, solid/liquid ratio .
investigated the technical feasibility of increasing copper recovery by leaching and flotation of slag tailings using sulphuric acid solutions, without or with the addition of either ferric sulphate or hydrogen peroxide. However, the maximum copper extraction attained with the slag was modest at about 63%, whereas that obtained with the slag flotation tailings was as low as 33% (Urosevic et al ...

CoFePb alloys in ammonia/ammonium chloride solutions (Burzynska et al., 2008). Senenayake and coworkers also suggested it takes place during dissolution of ferronickel alloys with small amounts of cobalt and copper in ammoniaammonium carbonate solutions repliing the Caron process conditions (Senanayake et al., 2010). However, it has not been shown sofar that copper (II) ions play .
