New Applications

Background: Reuse of waste materials present in the technosphere, such as the metal mining tailings is becoming a more economical and energy-efficient method for obtaining the raw materials than the classical mining. Number of patents are presenting methods for tailings recycling, often in construction industry and metallurgy. At the same time, world market for metallic nanomaterials is rapidly increasing with numerous new applications and these two subjects should be connected. Methods: Paper presents the hypothesis that fine sludge from the metal mining tailings could be dominant source of the raw material for the nanotechnology. The idea is based on the fact that most of the usual publications present methodologies for synthesis of nanomaterials only from high-quality chemicals which is often expensive and unsustainable. Proposition here says, that it would be more economical to use the tailings as one of the technospheric wastes, directly by extracting the metal ions, selectively precipitating their cations and subsequently using them in nanotechnologies. Arguments are given by cross-comparison of the literature and patents on iron, bauxite, lead/zinc, copper, tailings and also the extraction of rare earth elements from tailing resources. Results: Metal mining tailings are shown to be an emerging subject in various research papers and patents together with other secondary raw materials. Conclusions: Use of the metal mining tailings as the resources in nanotechnology, is a large energy-saving potential. Taking advantage of this readily available technospheric waste which contains mostly micrometer particles, should contribute also to the zero-metal waste goals.

The principles of blending control are explained with particular reference to a control scheme currently being implemented by G.E.C. Computers & Automation Ltd. for Skanska Cement AB at their Limhamn cement works. The control principles can, however, be applied to other blending plants. The Limhamn blending process is briefly described in order to give an appreciation of the control problems involved. The computer, instrumentation and X-ray analysing systems are outlined. The iterative optimiser is explained. This calculates set points for the material flows which, when implemented, result in manufacture of slurry with correct chemical composition at minimum cost. On-line regulating techniques which control the blending machinery are described. The regulating programmes maintain material flows at their calculated set point values. They also control water addition in order to keep slurry water content constant. Distinct advantages are to be obtained by the separate implementation of the optimising calculations or the regulating control, but the two are complementary, and to obtain maximum benefits, a computer control scheme should include both.
