In this inter-, intra- and trans-disciplinary book the material/metal cycle will be central, addressing technology as the basis for achieving sustainability within the system of primary mineral and metal producing, and the consumer product material cycles, linked to nature's cycles. The following major topics (not exclusive) are discussed in a detail, which will satisfy company CEO's and students of environment, engineering, economics, and law alike: (i) industrial ecology, (ii) system engineering concepts, (iii) development of future breakthrough technology as well optimization of present technology, (iv) process fundamentals (e.g. thermodynamics, separation physics, transport processes etc.), (v) product manufacture and design (for recycling), (vi) environmental legislation and (vii) technology as a basis for achieving sustainability within our present society.

The book discusses contentious issues such as the limits of recycling determined by physics, chemistry, economics and process technology, therefore providing the reader with a fundamental basis to understand and critically discuss the validity of environmental legislation. Furthermore, the 'Web of Metals' (i.e. the dynamic interconnection of metal and material cycles and product systems) will reveal that, if the application of environmental evaluation techniques such as material flow analysis, life cycle assessment etc. are not carried out on a sufficient theoretical basis, technological and economic understanding, analyses could lead to erroneous and in the end environmentally harmful conclusions.

The book is illustrated with many industrial examples embracing car and electronic consumer goods manufacturing and recycling, and the production and recycling of all major metals (e.g. steel, aluminium, copper, zinc, lead, magnesium, PGM's and PM's) and to an extent plastics. A complete section of the book is devoted to the recycling of light metals. Numerous colour figures and photos, plant and reactor data as well as software and computer models (running under Matlab's Simulink® and AMPL® as well as tools based on neural net technology (CSense™) are provided to give the reader the opportunity to investigate the various topics addressed in this book at various levels of depth and theoretical sophistication, providing a wealth of information, share-data and industrial know-how.

Finally, the book philosophically discusses how to harmonize the resource, life and technological cycles depicted by the figure on the cover to make a contribution to the sustainable use of resources and products.

A two model approach is outlined. It is based on a division between lumps and fines both having a model of their own. The models are coupled together so that fines produced in lump model are incorporated in the fines model. This approach is to be able to explain the formation and behaviour of critical size material. It is shown that the formation of critical material can be explained by taking into account the critical energies for grinding and comparing them to the energy available.

The ore consists of apatite, phlogopite mica and calcite. The ore is mined from open pit, crushed in three stages with a primary gyratory and a two stage cone crushing in closed circuit with screens. Ore is thoroughly homogenized by using stacking and reclaiming. The two parallel milling circuits are rather conventional ones. They consist of an open circuit rod mill and a ball mill in closed circuit with classifiers. The products of both mills are fed to a cyclone battery. The overflow goes to flotation and the underflow is reclassified in cone classifiers. The cone classifier underflow is fed back to the ball mill and the overflow goes to flotation. In the older line both the mills are 4 m diameter x 6 m with 1700 kW motors. In the newer line the rod mill is 4.5 m diameter x 6.5 m and the ball mill 4.9 m diameter x 6.5 m with 1700 kW and 2 x 1700 kW motors, respectively. Cyclones are of 500 mm...
