Selective Tin precipitation, leaving copper in Sulfate ...thanks for the reply. I know the cementation works well. I can drop the tin with zinc after the copper comes out. Its just that i want to leave the copper in solution to put through the SX/EW plant, due to the operation i have to leave the tin residue behind in the filter when i pump the solution out.

Copper + Tin + People: Public CoSmelting Experimentation ...Four hypotheses for bronze production have been proposed in the literature on this topic: (1) alloying metallic copper and metallic tin in a melting operation; (2) adding one of the metals to the other while still ore, in a cementation operation; (3) smelting naturally occurring copper ores containing tin (4) or smelting tin ores with copper ores, in a cosmelting operation. It has generally ...
Treatment of Industrial Brass Wastes for the Recovery of ...Negligible amount of copper was also dissolved in the same conditions and this copper could be precipitated by cementation. Pure zinc of % and % were produced by electrowinning of purified brass ash and flue dust leach solutions, respectively. Leach residue containing high amount of copper was melted with various fluxes and more than 99% of copper recovery ratio was achieved. Keywords ...

EXTRACTION OF METALS FROM SULPHIDE ORES BY WET . · Copper sulphate and ferrous sulphate had been produced by atmospheric oxidation or "weathering" about the fifteenth or sixteenth century, but except for occasional "cementation" of copper from the sulphate solution by the addition of metallic iron, it is doubtful whether this procedure was seriously considered as a method of extracting copper metal from ore. By midcentury the rapidly ...

Hydrometallurgy of CopperThe crystals are shoveled with copper shovels into this hopper, which fills the pushcar underneath through a spout with slide in the center. As the tanks are 6 ft. deep, the crystals have to be thrown at least 7 ft. high, and in doing this work some of the crystals unavoidably fall back into the tank, frequently striking the shoveler. It was
The Effect of Certain Surfactants on the Cementation of ... · Experiments were carried out in the presence of copper to increase the low cementation rate of nickel. The reaction of nickel cementation was found not to follow firstorder kinetics due to hydrogen evolution which takes place along with the cementation reaction. Two rate regions were observed. Hydrogen evolution in the presence of D1 is lower than with D2, D3 and without .
