This book was released on 1984 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The results are reported of experiments on the influence of a number of variables on the rate of loading of gold cyanide onto activated carbon and the equilibrium capacity of the carbon. These variables include the concentrations of gold and free cyanide in solution, the pH value and ionic strength of the solution, the concentration of organic compounds in the solution, the temperature, the particle size of the carbon, and the mixing efficiency. The experiments were carried out under approximately steady-state conditions to simulate the conditions in a countercurrent carbon-in-pulp absorption plant. In addition, the results are reported of experiments to establish whether the absorption of gold cyanide onto activated carbon is a reversible process.

Book excerpt: A study of the rate of elution of aurocyanide from activated carbon in small laboratory reactors is reported. The effects of various operating parameters such as the concentrations of cyanide, hydroxide, and gold in the eluant, the temperature, and the flowrate of the eluant on the rate were investigated. A semi-empirical kinetic model, which was previously developed for the adsorption of gold on to activated carbon, is shown also to describe quantitatively the kinetics of elution. This model is extended to the description of the rate of elution of carbon from fixed bed columns by the Zadra elution procedure. The electrowinning of gold in closed circuit with the elution column is included as part of the model. The use of the model in the prediction and optimization of the performance of actual elution plants is also described.

Available in PDF, EPUB and Kindle. Book excerpt: This state-of-the-art volume represents the first comprehensively written book which focuses on the new field of biosorption. This fascinating work conveys essential fundamental information and outlines the perspectives of biosorption. It summarizes the metal-sorbing properties of nonliving bacterial, fungal, and algal biomass, plus highlights relevant metal-binding mechanisms. This volume also discusses the aspects of obtaining and processing microbial biomass and metal-chelating chemicals into industrially applicable biosorbent products. Microbiologists, chemists, and engineers with an interest in new technological and scientific horizons will find this reference indispensable.

Download or read book Advances in Hydrometallurgy written by Alexandre Chagnes and published by MDPI. This book was released on 2020-05-22 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development of new technologies and the increasing demand for mineral resources from emerging countries are responsible for significant tensions in the pricing of non-ferrous metals. Some metals have become strategic and critical because they are used in many technological applications such as flat panel TVs (indium), solar panel cells (indium), lithium-ion batteries for electric vehicles (lithium, cobalt), magnets (rare earth elements, such as neodymium and dysprosium), scintillators (rare earths), and aviation and medical applications (titanium); their availabilities remain limited. The secured supply of these metals is crucial to continue producing and exporting these technologies, and because the specific properties of these metals make them essential and difficult to substitute for a given industrial application. Hydrometallurgy have the advantages of being able to process low-grade ores, to allow better control of co-products, and have a lower environmental impact providing that the hydrometallurgical route is optimized and cheap. The need to develop sustainable, efficient, and cheap processes to extract metals from complex and poor polymetallic matrices is real. The aim of this book was to highlight recent advances related to hydrometallurgy to face new challenges in metal production.
