Question

How will you bring about the separation and determination of copper and nickel from
alloy?
​

Answer 1

Answer:

Liquation is a metallurgical method for separating metals from an ore or alloy. The material must be heated until one of the metals starts to melt and drain away from the other and can be collected.

BUT

If you want to separate the metals then I would use the following method, I would dissolve the coins by immersing them in hydrochloric acid with air present. This will convert the nickel / copper alloy into a solution of copper chloride and nickel chloride.

Hope it helps you
