This book discusses various examples on the use of ion exchange in chemical processing, mainly in aqueous systems but also in non-aqueous systems and in gas streams. The theory behind these examples is briefly discussed in order to make the subjects better understood. The focus is on ion exchange rather than on chemical processing, it is therefore addressed to all those working in chemical processing industries or in parallel industries for whom ion exchange is not their primary field of experience.

This edited volume includes all papers presented at the 22nd International Conference on Mine Planning and Equipment Selection (MPES), Dresden, Germany, 2013. Mineral Resources are needed for almost all processes of modern life, whilst the mining industry is facing strict requirements regarding efficiency and sustainability. The research papers in this volume deal with the latest developments and research results in the fields of mining, machinery, automatization and environment protection.

This is a description of a process and of the development of the process and of a machine for the recovery of uranium from acid slurries without accomplishing a liquid-solid separation. Metallurgical results obtained from testing two ores from the White Canyon area of Utah.

Resin-in-pulp (RIP) technology was developed for the recovery of valuable metals from high volumes of low grade pulps, as is the case with gold processing. More recently, the application of this technology has been evaluated for the recovery of soluble losses of valuable metals from solid residues in base metal plants. For this type of application, the RIP process will improve overall plant recoveries, especially where solid- liquid separation proves difficult as a result of poor filterability or settling characteristics of the solids. An added benefit of the RIP process is a reduction in the environmental impact of the solid residues contaminated with entrained base metals from the plant. Mintek investigated the metallurgical and economic feasibility of using RIP technology for the recovery of soluble cobalt, nickel and copper from thickener underflows on behalf of Anglovaal Mining. Laboratory and mini- plant investigations included the recovery of copper with RIP, followed by simultaneous nickel and cobalt recovery using a second RIP circuit. Recovery of copper, nickel and cobalt in a single RIP circuit was also investigated.
