This means that to extract 1 mole of silver, we need 1/2 mole of argentite. To convert moles to grams, we multiply by the molar mass. Minimum mass of argentite = (1/2 mole) × (molar mass of Ag₂S) = (1/2 mole) × (247.81 g/mol) = 123.91 g Therefore, the minimum mass of argentite from which pure silver could be extracted is 123.91 grams.

The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( CuFeS2 C u F e S 2) 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.
Hint: To answer this question, you should recall the concept of the froth flotation process. This process is used for mineral beneficiation. In ore/mineral beneficiation, froth flotation is a method by which commercially important minerals are separated from impurities and other minerals by collecting them on the surface of a froth layer.
