Silica in Hydrometallurgy: An Overview

Canadian Metallurgical Quarterly, 1986
AbstractSilicon is the second most abundant element in the earth's crust; thus, familiarity with the behavior of silica in wet processing systems is important to the hydrometallurgist. Plant problems originating from silica are numerous. These problems often occur in the high-tonnage, high-volume portion of the flowsheet.

Hydrometallurgy and Electrometallurgy

2016
In Chapter 8 we examined some traditional techniques for the production of “tonnage” metals such as steel, aluminum, and copper. These techniques involved high temperature, molten metals, and slags and difficulties posed by the emission into the environment of particles, sulfur dioxide, and so on.

Binary Extraction in Hydrometallurgy

Mineral Processing and Extractive Metallurgy Review, 2000
Abstract Results obtained during technological application of binary extraction (extraction by salts of organic acids and organic bases) for recovery and separation of non-ferrous, rare, noble and associated metals are presented in the paper. The method of extraction of copper, especially from leaching solutions of oxidised ores, with the use of ...

Hydrometallurgy in the mining industry

Metallurgist, 2008
There are many links between microbiology and mining, and the number of such ties is continuing to grow. With its methods, concepts, and — ultimately — its products, modern chemistry is determining the technology of the future. However, research is needed in many different areas in order for this to continue. At the same time, development of the latest

A novel oxidant for nickel hydrometallurgy

Hydrometallurgy, 1979
Abstract Nickelic hydroxide is an important metallurgical reagent used for precipitating cobalt from nickel sulfate solutions. Existing methods of preparation of nickelic hydroxide involve electrolytic oxidation of Ni(OH)2 or the use of strong oxidizing agents such as chlorine, ozone and persulfate.

The Hydrometallurgy of Gold Processing

Interdisciplinary Science Reviews, 1992
AbstractGold has captured mankind's admiration for centuries as a medium of currency or exchange, for personal jewellery and for decorative and ornamental purposes. The mythical tale of Jason and the Golden Fleece may have its origins in the placer miners' technique of placing sheep's fleeces in sluices to capture gold flakes.

Mechanical activation in hydrometallurgy

International Journal of Mineral Processing, 2003
Abstract The review paper deals with the results of the utilization of mechanical activation in hydrometallurgy. The definition of mechanochemistry is given as well as physicochemical changes in mechanically activated minerals are described. The enhancement of the leaching processes in hydrometallurgy is illustrated.
