Aug 21, 2020018332The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite CuFeS2 are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite also known as copper pyrites and similar sulfide ores are the commonest ores of copper.

Copper is found in the Earth237s crust as an ore containing copper sulfide. Large areas of land, where this ore was once quarried, are contaminated with low percentages of copper sulfide. Copper would be too expensive to extract from this contaminated land using the traditional method of quarrying and then heating in a furnace.

c Copper ore contains copper carbonate, CuCO 3. In the first stage of the extraction process, the copper carbonate is decomposed by heating to form copper oxide, CuO, and carbon dioxide. CuCO 3 → CuO CO 2 When 100g of copper carbonate is decomposed completely in this way, it is found that the total mass of products is 100g.

We can work out the number of molecules by timesing the moles by Avogadros constant above. Now we know the amount of molecules of HCl we have, and, since the reaction is 11, we need the exact same number of molecules of NaOH to neutralise it. As we need to find the mass of NaOH to add, lets quickly rearrange the equation
