Microscale extraction of copper Learn Chemistry
Microscale extraction of copper. Copper oxide can be reduced to copper using hydrogen. This reaction is usually done as a large scale demonstration, but this microscale version can be done by students. This can be used to show the relative positions of copper and hydrogen in the reactivity series and can also be used for percentage yieldtype calculations.

COPPER(II) EXTRACTION FROM AMMONIA LEACH SOLUTION
Copper(II) extraction from ammonia leach solution 329 more costeffective, because it requires less stages comparing to the first way of separation. The concept of coextraction (selective stripping) was used for many metal couples. It was also adopted in ammonia systems for CuNi separation.
Extraction Equilibrium of Copper from Ammoniacal Media ...
Abstract This paper reports a study of the extraction of copper from ammonia/ammonium sulfate medium with LIX 54, a β‐diketone. The extraction of copper is very sensitive to the equilibrium pH. The highest extraction efficiency is attained in the range of pH 8– Above pH 10, the percentage of metal ion extracted decreases sharply. The extraction of copper by LIX 54 can be described by ...
