Available in PDF, EPUB and Kindle. Book excerpt: Pyrite Oxidation and its Control is the single available text on the market that presents the latest findings on pyrite oxidation and acid mine drainage (AMD). This new information is an indispensable reference for generating new concepts and technologies for controlling pyrite oxidation. This book focuses on pyrite oxidation theory, experimental findings on oxidation mechanisms, as well as applications and limitations of amelioration technologies. The text also includes discussions on the theory and potential application of novel pyrite microencapsulation technologies for controlling pyrite oxidation currently under investigation in the author's laboratory.

This book was released on 2013-07-30 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book highlights and analyses the distress to buildings caused by sulphate-induced heave, with particular reference to the recent problems in the Dublin area of Ireland. It describes the formation of pyrite, the processes involved in its oxidation and the various ways in which consequential expansion takes place. For the first time in the literature it discusses the way that buildings can be raised above their supporting foundation walls by the expansion of pyritiferous fill which has been used beneath ground-bearing floor slabs in Ireland. The significance of fractures through the iron sulphide microcrystals for the rate and extent of oxidation is discussed. Photographs and profiles of sulphate ingress into concrete/concrete blocks are presented. Case histories from the UK, North America and Ireland are discussed.

This book was released on 2014 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Acid mine drainage (AMD), an acidic and dissolved metal effluent from oxidative dissolution of sulphide minerals, particularly pyrite, in waste rock dumps and tailings dams, has serious impacts on the receiving environment. Legislation on mine waste management and AMD emission and heavy financial burdens for AMD treatment have forced mining operators to look for improved, cost-effective alternatives for reducing acid generation from the source during mining operations and after closure of the mine. Currently, there are many options to diminish sulphide or pyrite oxidation including passivating barrier methods that aim to isolate pyrite surfaces from oxygen or water, chemical additives and inhibition of iron-oxidising and sulphide oxidising bacteria. Moderation of pyrite oxidation can significantly lower acid generation rates and reduce AMD emission. This dissertation is composed of fundamental and applied studies that aim to understand formation conditions of surface coatings on pyrite surface and the effectiveness of these coatings in preventing the oxidation process which is the primary source of acid mine drainage.

Download or read book The Effects of Various Gas Atmospheres on the Oxidation of Coal Mine Pyrites written by John D. Robins and published by . This book was released on 1971 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experiments up to 150 days in length were conducted to study the acid production rate of coal mine pyrites under various gas atmospheres. The gas atmospheres studied were air, nitrogen, methane, and carbon dioxide. The lower limits of the oxidation process were studied by introducing small amounts of oxygen along with the inert blanketing gas and by studying the effects of deaerated versus air saturated feedwater. Acid production was proportional to the available oxygen partial pressure. The acid parameters monitored continued to change and had not completely reached a steady state by the termination of the work. The acid production of nitrogen blanketed pyrite decreased to less than 1% of that of identical columns under air atmosphere. Nitrogen and methane gases were equally effective in reducing acid production. Both of these gases were slightly more effective than carbon dioxide. A large amount of detailed experimental data is presented.

This book was released on 2009 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: The abiotic oxidation of pyrite requires the supply of oxygen and water only. In abiotic systems, pyrite oxidation may proceed via several paths, with multiple steps in each of the paths. Defect sites (S-deficient, Fe3+ bearing sites) on the pyrite surface have been shown reported to be the initial reaction sites on pristine pyrite surfaces. In neutral to slightly acidic solutions (3.5

Available in PDF, EPUB and Kindle. Book excerpt: Laboratory studies demonstrated the feasibility of using the Mossbauer effect and a backscattering mode of detecting 14.4 Kev gamma rays to spectroscopically monitor the oxidation processes taking place on pyrite materials. A cobaltous oxide form of cobalt-57 was the radiation source. Spectra were obtained of pyritic surfaces under 2 mm of water. Differentiation of nonoxidized and oxidized pyritic surfaces was possible with further separation of the spectra to show individual oxidation product peaks suggesting ferric hydroxide and ferric sulfate.
