cementation of copper with iron

copper leaching equipment supplier in china

In this study, the cementation of copper ions on iron and zinc as sacial metals in a fluidized bed configuration was carried out. A preliminary hydrodynamic study checked the non-segregating behaviour of iron/zinc mixtures during fluidization experiments.

Cementation of copper with iron powder was tested in the laboratory to remove copper from a mixed-metal electroplating sludge leach solution(2). powder (M /M = 10) slurried into the mixed-metif s%ution for one-half hour with a A large excess of iron . solution ...

Static leaching copper ore

In this paper, the parameters affecting the process of copper cementation, its optimization and kinetic investigation are studied. For this purpose, the main parameters, such as pH, copper concentrations, stirring speed, reaction time and the kinetics of the cementation process have been investigated by using the experimental design method. The results show that the three parameters of ...

Mar 22, 1977· For a multiple vat leaching operation, the concentrated leach liquor is combined into one large volume of concentrated pregnant leach liquor for subsequent mineral value recovery, such as reduction of metal values by electrowinning and chemical reduction (e.g., by hydrogen reduction or cementation of copper with iron).

Surface deposit effects in the kinetics of copper ...

In the search for lower cost methods of recovering copper, the use of sponge iron or particulate iron (as distinguished from iron powder used in powder metallurgy) as precipitants in place of tin cans, detinned scrap iron, or scrap iron is an intriguing possibility. The relatively faster copper precipitation rate obtained with particulate iron as compared to scrap iron promises economic and ...

cementation copper process cone iron scrap

Recent increases in the production of copper by acid-leaching techniques have depleted the supply of iron and de-tinned cans as sources of precipitant for copper from solution. Previous investigators of the iron cementation process have indicated that high purity iron powder, although more costly than detinned cans, has several properties which render it a potential precipitant of copper from ...
