The Extraction and Refining of Metals provides a novel approach to the science and technology of both ferrous and non-ferrous metal production. Rather than the traditional treatment in which one metal at a time is considered, this new approach, which examines several metals at a time, reveals more clearly the versatility and limitations of each of the main types of process. The restrictions imposed on the selection of the process routes by thermodynamic and kinetic factors and by economic and environmental constraints are examined in detail. The conservation of energy and materials is emphasized and illustrated by the description of new and improved extraction methods. The types of mathematical models that are being developed for computer control of production operations are indicated, and worked examples demonstrate relevant thermodynamic and mass balance calculations.Recycling thus conserves the stock of ores in the ground, resulting in less rapid deterioration in the average metal ... Costs may be lowered when some recycled scrap metal can be incorporated in the charge for the refining of new metal.
