Acid Leaching

Malachite is a fairly hard rock, but copper oxide is very soft and crumbly. This is because it gets broken up as the carbon dioxide comes out of it. As the rocks crumbled, more of the copper oxide would have been moved into the middle of the fire where it got hotter. Add the copper oxide to the beaker and add the carbon.
