During the period of April 27 to June 8, 1956, Rio de Oro Dysart Shaft Ore from the Ambrosia Lake District, New Mexico, was treated in the Acid Leach - Resin-In-Pulp Pilot Plant at Grand Junction, Colorado. The report contains information on grinding, leaching, sand-slime separation, ion exchange, solvent extraction of H2SO4 pregnant eluates, and precipitation. Results show the ore to be amenable to the Resin-In-Pulp process.

During the period of February 10 to May 8, 1958, Holly Blend ore from the Holly Minerals Company of the Ambrosia Lake district in New Mexico was treated in the Acid Leach - Contercurrent Decantation - Solvent Extraction Pilot Plant at Grand Junction, Colorado. This report contains detailed information on leaching, as applied in the processing of this ore. Results show the ore to be amenable to the Acid Leach - Countercurrent Decantation - Solvent Extraction process.

The preliminary operation of the Acid Leach - CCD - Solvent Extraction Pilot Plant at Grand Junction, Colorado, was conducted from November 8, 1956 to January 3, 1957 using White Canyon ores. The report contains information on the grinding, leaching, and liquid-solid separation by continuous countercurrent decantation. Detailed information is presented on the liquid-liquid solvent extraction of the leach liquor using organic solvents containing di-2-ethylhexyl phosphoric acid or triisooctyl amine. Results show White Canyon ores to be amenable to the Acid Leach - CCD - Solvent Extraction process. Using di-2-ethylhexyl phosphoric acid, reagent consumptions were relatively high, whereas with triisooctyl amine excellent recovery of uranium was obtained with moderate reagent requirements.

The treatment of contaminated soil is a permanently relevant subject for ensuirng the quality of the environment. A wide variety of soils contaminated witht a broad range of harmful chemical compounds all around the the world, call for many different treatment strategies. Research activities focus on affordable methods offering the greatest possible effect, whilst limiting the potential side effects. This book sums up the research activities of Research Centre 188 which has cooperated with the Technical University of Hamburg-Harburg, the University of Hamburg and GKSS in Geesthacht over the last 12 years, thus greatly advancing our knowledge in this field.

Hydrometallurgy '94 contains the 78 papers that were presented at the international symposium organized by the Institution of Mining and Metallurgy and the Society of Chemical Industry and held in Cambridge, England, in July 1994. In the papers specific attention is paid to the concept of sustainable development and the associated ideas of cleaner technology, recycling and waste minimization that have particular relevance to the extractiona nd processing of metals and other mineral products. The papers, by authors from 30 contries, are grouped under the headings: Hydrometallurgy and Sustainable Development; Materials Production and the Environment; Fundamentals; Leaching; Bioprocessing; Gold Solution Purification; Effluent Treatment; Processes; and Recycling.
