Download and read online ebook Leaching Kinetics of Valuable Metals write by Stefano Ubaldini. This book was released on 2021-05-07. Leaching Kinetics of Valuable Metals available in PDF, EPUB and Kindle. Leaching is a primary extractive operation in hydrometallurgical processing, by which a metal of interest is transferred from naturally occurring minerals into an aqueous solution. In essence, it involves the selective dissolution of valuable minerals, where the ore, concentrate, or matte is brought into contact with an active chemical solution known as a leach solution. Currently, the hydrometallurgical processes have a great number of applications, not only in the mining sector—in particular, for the recovery of precious metals—but also in the environmental sector, for the recovery of toxic metals from wastes of various types, and their reuse as valuable metals, after purification. Therefore, there is an increasing need to develop novel solutions, to implement environmentally sustainable practices in the recovery of these valuable and precious metals, with particular reference to critical metals; those included in materials that are indispensable to modern life and for which an exponential increase in consumption is already a reality, or will be in a short-term perspective. For publication in this Special Issue, consideration has been given to articles that contribute to the optimization of the kinetic conditions of innovative hydrometallurgical processes—economic and of low environmental impact—applied to the recovery of valuable and critical metals.

Download and read online ebook Weathered Crust Elution-deposited Rare Earth Ores write by Ruan Chi. This book was released on 2008. Weathered Crust Elution-deposited Rare Earth Ores available in PDF, EPUB and Kindle. Weathered crust elution - deposited rare earth ore (original name is the ion-adsorbed rare earth ore) was first discovered as a novel exogenous ore in Jiangxi province of China in 1969. There are many advantages for the ore which has a widespread distribution, rich reserves, low radioactivity, complete RE partitioning and is rich in middle and heavy rare earth. Especially, the middle and heavy rare earth which occupies 80% over the world is the unique mineral resource in China, distributing only in southern China such as Jiangxi, Fujian, Hunan, Guangdong and Guangxi et al.

This book was released on 1990. Gold available in PDF, EPUB and Kindle. The eight articles first appeared as volume 6 (no date) of Mineral processing and extractive metallurgy review. They review new methods of recovery for gold, and to some extent, silver, focus on the particular challenges of extraction from carbonaceous ores and from various sulfide-bearing ore, and the treatment of refractory gold ore, and discuss high-temperature and biological oxidation, high- temperature chlorination, and removing metals from leach liquor.
