Malachite is a copper ore consisting mainly of basic copper(II) carbonate, CuCO3.Cu(OH)2. In this experiment, students learn how to produce copper from copper(II) carbonate by heating it to produce copper(II) oxide, which is then reduced to the metal using carbon …

Aim: To investigate the reduction of copper oxide using carbon. Materials: copper oxide, anhydrous sodium carbonate, charcoal block, blow pipe, burner. The reduction of copper using carbon. Method. Mix a little copper oxide with sodium carbonate. Place the mixture in a small hole in a charcoal block. Heat the mixture strongly using a blow pipe ...

Metals ranked below carbon (lead, iron, copper) can accept charges from carbon. Metals ranked above carbon are more reactive than carbon, and therefore need to extracted by using carbon as ...

However, in practice, modern copper smelters can actually manage the extraction without using carbon (coke) and then electrolysis is usually used to purify the impure copper from the smelter. The metal copper can be easily extracted BUT copper–rich ores are becoming scarce so new methods of extracting copper are being developed to exploit low ...

This method of extraction works because carbon is more reactive than iron, so it can displace. iron from iron compounds. Extracting a metal by heating with carbon is cheaper than using electrolysis.

2. Cover the pile of malachite and carbon with a 0.5cm layer of carbon powder. Your crucible should be one half to two thirds full. 3. Put the crucible on a tripod and pipe clay triangle and heat very strongly. (Beware sparks). After 5mins put the lid on the crucible. 4. After 10mins remove the lid of the crucible and use the Bunsen burner to ...

(copper, rare earth elements and cobalt) and how impacts can be reduced through the transition to a circular, low-carbon economy. Performance in the global industry is extremely variable. Some businesses operate to high standards within a framework that facilitates the re-use and recycling of metals and other materials.

Answer (1 of 3): Complex story, let's try to keep it simple. The ore/concentrate can be a sulfide or an oxide. If sulfide, it also generally contains precious metals. It is therefore melted with fluxes and we get two phases in the furnace: molten sulfide under and oxide slag on top. The molten s...

In this experiment, students heat two metal oxides with powdered charcoal. If the carbon is more reactive than the metal it will remove the oxygen from the metal oxide and leave traces of the metal in the reaction vessel. Students try lead(II) oxide first, before using a slightly modified technique to try copper(II) oxide.
