See plate of West Driefontein Gold Mine with this add. The West Driefontein Gold Mine with the reduction works in the foreground. In 1977 2:27 million tonnes of ore wee mined to produce 53 tonnes of gold. This survey describes the essential part played in our lives at home and in industry and civilization, by metals as common as iron and as rare as praseodymium. The distribution of metals is discussed, with an analysis of the Earth's crust and descriptions of the mining and smelting of metallic ores and of the blending of metals to form alloys. Later chapters look at the properties and uses of all the major and minor metals, the use of metals in nuclear energy, the shaping of metals for tasks as varied as the making of a needle and a high-pressure gas cylinder, the casting of a bronze statue and a large marine propeller, and the latest methods of steel-making.
