Available in PDF, EPUB and Kindle. Book excerpt: Results of recent experimental studies and modern theoretical concepts are combined in this volume to provide a comprehensive analysis of sulfide mineral oxidation processes. Introductory chapters discuss the properties of sulfide minerals and various investigative techniques, followed by chapters on oxidation mechanisms and the behavior of minerals under these various oxidizing conditions. This book also demonstrates modern methods of physical-chemical modelling and the regulation and optimization of flotation processes.

Book excerpt: The issue of iron-sulfide degradation in concrete aggregates has proven to be a major problem in concrete infrastructure, causing insufficient concrete durability and extensive structural damages which include expansion, cracking, and popouts. Over the years, there have been various reports of iron-sulfide minerals like pyrite and pyrrhotite causing oxidation reactions and leading to extensive residential concrete foundation damage in Connecticut and Quebec, Canada. In many of these cases, damages have been so serious to the structural integrity of the structures that immediate remediation has been required to repair the deterioration. The issue is not well documented despite reports of damage in the United States, Canada, and parts of Europe. Currently, there are limited existing standardized testing methods or mitigation strategies for the presence of iron-sulfide minerals in concrete aggregates because the mechanisms by which degradation occurs are not fully understood. The objective of this research is to experimentally measure the kinetics of iron-sulfide oxidation reactions in dissolution systems with oxidizing agents and analyze existing dissolution rate data available to assist in determining the factors that influence the deterioration of aggregates used in concrete infrastructure.

This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Rates and products of the oxidation of diphenyl sulfide, phenyl methyl sulfide, p-chlorophenyl methyl sulfide and diphenyl sulfoxide have been determined. Oxidants included t-Bu02H alone, t-Bu02H plus molybdenum or vanadium catalysts and the molybdenum peroxo complex Mo0(02)2*HMPT. Reactions were chiefly carried out in ethanol at temperatures ranging from 20° to 65°C. Oxidation of diphenyl sulfide by t-Bu02H in absolute ethanol at 65°C followed second-order kinetics with k2 = 5.61 x 10 G M~1s"1, and yielded only diphenyl sulfoxide. The Mo(C0)g-catalyzed reaction gave both the sulfoxide and the sulfone with consecutive third-order kinetics. Rate = k3[Mo][t-Bu02H][Ph2S] + k^[Mo][t-Bu02H][Ph2S0], where log k3 = 12.62 - 18500/RT, and log k^ = 10.73 - 17400/RT. In the absence of diphenyl sulfide, diphenyl sulfoxide did not react with t-Bu02H plus molybdenum catalysts, but was oxidized by t-Bu02H-V0(acac)2. The uncatalyzed oxidation of phenyl methyl sulfide by t-Bu02H in absolute ethanol at 65°C gave a second-order rate constant, k = 3.48 x 10~"5 M^s""1. With added Mo(C0)g, the product was mainly phenyl methyl sulfoxide; Rate = k3[Mo][t-Bu02H][PhSCH3] where log k3 = 22.0 - 44500/RT. Both diphenyl sulfide and diphenyl sulfoxide react readily with the molybdenum peroxy complex, Mo0(02)2'HMPT in absolute ethanol at 35°C, yielding diphenyl sulfone. The observed features are mainly in agreement with the literature on metal ion-catalyzed oxidations of organic compounds by hydroperoxides. These indicate the formation of an active catalyst and the complexation of t-Bu02H with the catalyst. However, the relatively large difference between the activation energies for diphenyl sulfide and phenyl methyl sulfide, and the non-reactivity of diphenyl sulfoxide suggest the involvement of sulfide in the production of an active species.
