  • Limestone Resources of Western Washington
    State of Washington DANIEL J. EVANS, Governor Department of Conservation H. MA URI CE AHLQUIST, Director DIVISION OF MINES AND GEOLOGY MARSHALL T. HUNTTING, Supervisor Bulletin No. 52 LIMESTONE RESOURCES OF WESTERN WASHINGTON By WILBERT R. DANNER With a section on the UME MOUNTAIN DEPOSIT By GERALD W. THORSEN STATII PRINTING PLANT, OLYMPI A, WASH, 1966 For sale by Department of Conservation, Olympia, Washington. Price, $4,50 FOREWORD Since the early days of Washington's statehood, limestone has been recognized as one of the important mineral resources _of the State. The second annual report of the Washington Geological Survey, published in 1903, gave details on the State's limestone deposits, and in later years five other reports published by the Survey and its successor agencies hove given additional information on this resource. Still other reports by Federal and private agencies hove been published in response to demands for data on limestone here. Although some of the earlier reports included analyses to show the purity of the rocks, very few of the samples for analysis were taken systemati­ cally in a way that would fairly represent the deposits sampled. Prior to 1900 limestone was produced for use as building stone here, and another important use was for the production of burned Ii me . Portland cement plants soon became leading consumers of Ii mestone, and they con­ tinue as such to the present time . Limestone is used in large quantities in the pulp industry in the Northwest, and in 1966 there was one commercial lime-burning plant in the State. Recognizing the potential for industrial development in Washington based on more intensive use of our mineral resources, and recognizing the need to up-dote the State's knowledge of raw material resources in order to channel those resources into the State's growing economy, the Industrial Row Materials Advisory Committee of the Deportment of Commerce and Economic Development in 1958 recommended that a comprehensive survey be made of the limestone resources of Washington.

  • Crude Ticl4 Purification: a Review of the Current State of the Art and Future Opportunities
    Crude TiCl4 purification: a review of the current state of the art and future opportunities L. Hockaday and A. Kale Mintek, Randburg, South Africa Raw titanium tetrachloride (TiCl4) is produced by chlorination of titania feedstock. Prior to its utilization in the manufacture of titanium dioxide pigment or titanium metal, the TiCl4 is purified by adding reagents that react with the impurities in the crude TiCl4, followed by distillation of the mixture. The current state of the art in purification of crude TiCl4 was surveyed. Tests were conducted at the laboratory scale to assess the efficiency of various additives used in the purification process to minimize the vanadium content in the distillate. The effects of various reagents, namely oleic acid, sodium oleate, potassium oleate, and copper on the purification of crude TiCl4 were compared. The purified TiCl4 was water-clear in aspect and analysed < 2 ppm vanadium for all reagents tested. Possible reactions between the impurities in the crude TiCl4 and the reagents are investigated thermodynamically with the FactSage program. INTRODUCTION Titanium tetrachloride (TiCl4) is obtained by the chlorination of a titanium-bearing mineral such as ilmenite and rutile, as well as from titanium slag. The chlorination process usually takes place in a fluidized bed in the presence of chlorine gas and a reducing agent such as petroleum coke, resulting in crude titanium tetrachloride. TiCl4 is an intermediate product in the production of titanium dioxide (TiO2) pigment and titanium metal. The pure form of titanium dioxide is used in the pigment industry for paints, food colouring etc., and titanium metal is widely used in the aerospace, medicine, sport, and semiconductor production industries.

License and terms: see end of document. Abstract This review highlights the state of the art in the field of continuous flow nitration with miniaturized devices. Although nitration has been one of the oldest and most important unit reactions, the advent of miniaturized devices has paved the way for new opportuni- ties to reconsider the conventional approach for exothermic and selectivity sensitive nitration reactions. Four different approaches to flow nitration with microreactors are presented herein and discussed in view of their advantages, limitations and applicability of the information towards scale-up. Selected recent patents that disclose scale-up methodologies for continuous flow nitration are also briefly reviewed.

  • A Fundamental Study of the Alkaline Sulfide Leaching of Gold
    The European Journal of Mineral Processing and Environmental Protection Vol.3, No.3, 1303-0868, 2003, pp. 336-343 A fundamental study of the alkaline sulfide leaching of gold M.I. Jeffrey1* and C.G Anderson2 1 Department of Chemical Engineering, Monash University, Vic., 3800, Australia 2 The Center for Advanced Mineral and Metallurgical Processing, Montana Tech of the University of Montana, Butte, Montana, 59701, USA Received 19 September 2002; accepted 23 September 2003 ABSTRACT Due to the increasing concerns over the emission of sulfur dioxide from roasting and smelting, there has been an increased interest in pressure oxidation as a means of treating gold bearing ores and concentrates. One of the problems with the partial oxidation of the sulfide host matrix to form elemental sulfur is that sulfur containing streams are difficult to treat using cyanidation. In the present paper, the alkaline sulfide system was studied as an alternative to cyanide for recovering gold from elemental sulfur. It was found that the dominant lixiviant for gold in this system is sulfide, and polysulfide was ascertained to be the oxidant. The leaching reaction was determined to be chemically controlled, thus highly dependent on temperature. Other variables investigated include the effect of pH, gold purity, and the ratio of sulfide to polysulfides. It was found that each of these variables had a large impact on the system. © 2003 SDU. All rights reserved. Keywords: Hydrometallurgy; Leaching; Gold 1. INTRODUCTION Many gold ores are problematic as they contain metal sulfides, such as pyrite, arsenopyrite and chalcopyrite. These ores are often refractory, as the gold is encapsulated within the sulfide matrix.
