Separation of zinc from a zinc-copper alloy - Chempro ...

In accordance with the invention, zinc is separated from a zinc-copper alloy by reacting the alloy with an aqueous alkali metal bisulfate to dissolve zinc selectively with respect to copper. The zinc preferably is recovered from the resulting solution by precipitation in the form of an insoluble zinc compound. The solid residue remaining undissolved after the reaction with bisulfate contains the copper present in the alloy,

Zinc And Copper Separation From Brass

The simple answer is Brass. The combination of Copper and the percentages of Zinc make up copper alloys. 95 copper with 5 Zinc is called 210 Brass. 90 copper and 10 Zinc is call 220 Brass. For every 5 added Zinc the Copper alloy is raised by 10. 260 Brass is the most widely use combination of these two element. 260 Brass is 70 Copper and .
