Ammoniacal leaching followed by solvent extraction is practiced for the production of copper sulfate from copper dross generated in lead refinery during the pyro metallurgical production of lead. Copper is leached from its dross as Tetra-amino-Copper (II)-carbonate complex in the solution. Copper ...
Studies on the extraction of nickel and copper from the ammoniacal ammonium carbonate solution were undertaken using LIX 64N as an extractant. The solvent showed preference for extraction of copper over nickel from the ammoniacal solutions. The leach liquor of sea nodules from the Indian Ocean wa...
Recovery of copper from a sulfuric acid leaching solution of manganese nodules was studied by using KELEX 100, LIX 64 N and LIX 70. Extraction of each metal from sulfate solution of Cu2+, Ni2+, Co2+ Fe3+, and Mn2+, and of Cu from a synthetic leaching solution (Cu 6, Ni 6, Co ...
This study was the first-ever attempt to apply MIL-68 (Ga) in developing an analytical method. The method extracts and preconcentrates some parabens from mouthwash and hydrating gel samples. The variable extraction parameters were optimized, and the figu
Hydrometallurgical extraction of copper and other valuable metals A hydrometallurgical process for extracting copper and any one or more than one of zinc, silver and gold from a sulphide ore or concentrate is disclosed. The process includes a range of mineral species that contain copper and one or...

This work analyses the extraction of Cu(II) using quaternary ammonium and quaternary phosphonium based ionic liquids. Firstly, the chemical suitability of the two ionic liquids was evaluated. They were then tested for extracting copper from solutions (simulated) of liquid mining waste. The effects ...
LIX 973N diluted with Iberfluid was used to co-extract copper and nickel from ammoniacal/ammonium carbonate aqueous media. The influence of equilibration t... FJ Alguacil,A Cobo - 《Journal of Chemical Technology & Biotechnology》 被引量: 0发表: 1999年 Selective extraction agent strontium contai...
Li/Li+. A strong peak due to the deintercalation of Li from the carbon sample was also revealed on the anodic branch of the CV as in the case of bare carbon fiber. This is indicative of insertion of Li into carbon through the copper film. When the film thickness was thin enough, i....
COPPER PROCESS : The concentration of copper in ores averages only 0.6%, and most profitable ores are sulfides, especially chalcopyrite (CuFeS2) and to a lesser extent chalcocite (Cu2S). These minerals are intense from crushed ores to the level of 10 to 15% copper by froth flotation or bi...
