separation of copper and tin

The separation of the copper and tin groups by partition ...

This adsorption makes it impossible to separate a mixture of all the Copper and Tin group metals. However it does not interfere if only As+^, Sb+^ and Sn+^ are separated. For this separation a short chromatogram is made about 10 cm long. The separation is then complete as shown in Fig. 2. 7?e/6^cMee^ ^. ^o.

DISCUSSION The method should not be used as a separation of copper from more than 0.25-0.30 grams of tin, otherwise some contamination of the copper by the tin will occur (for instance a copper result of o.io26 g was obtained in electrolyzing o.zooo g of copper in the presence of 0.40 g Of tin). Ordinarily copper-base alloys tend to spatter ...

To separate the copper, I would suggest that you shake the copper / nickel mixture in hydrochloric acid with 30 % aliquat 336 diluted with aromatic kerosene (or ethyl benzene). Do this in a fume hood. The copper will be extracted by this solution of an ionic liquid in the aromatic solvent and the nickel will be left behind in the aqueous solution.

Separating Copper and Zinc from a Penny - HubPages

Apr 19, 2012  Separating Copper and Zinc from a Penny. Most people are under the assumption that pennies are made of copper, and that is partially true. Before 1982, pennies were 95% copper and 5% zinc. Due to the fact that the price of copper was rising, the US Mint had to change the penny's composition to keep the cost of pennies under one cent.
