How do you extract copper from copper II oxide?

Answer 1

this is the best way for making copper oxide

Get some copper and grind it up as small as possible. Once the filings are small enough, place them on a flat backing tray type thing (I found something which is use for cakes, it only needs to be flat and the size of a frying pan) Then go to the kitchen and find the biggest element on the stove, turn it up to full and place you pan thingy with the filings on it. After a few minutes you will start to see the filings change color, every now and then you will want to give the filings a toss and shake. You will want to keep the filings on the heat until they stop changing color.

I did this with copper filings (the copper filings were half oxidized in the oven, which took hours. When I put them on the element it was done in about 10minutes! It may take a bit longer as my filings were half oxidized, but they were larger filings so this could take about the same time)

Answer 2

By using Electrolysis.

No, not electrolysis. By heating copper in air , it will form copper oxide.Even reaction with steam gives copper oxide

heat (O2)

Copper ---------------> copper oxide

Copper + Steam (H2O) ---------> copper oxide

Copper + Water ---------> copper hydroxide

Answer 3

You can extract copper from copper II oxide through reduction method using hydrogen gas or CO. By passing hydrogen gas or carbon monoxide over heated copper II oxide you will be able to obtain copper metal.

Answer 4

Add the copper metal to sulphuric acid, if that doesn't work, try a mixture of hydrogen peroxide and sulphuric acid.

Answer 5

Reacting it with Oxygen or an oxidizing agent
