    Evaluation and audit of mine water management and treatment practices at South African gold and coal mines An assessment and audit of the mine water management and treatment practices employed on surface and underground, in the mines, metallurgical plants, potable and sewage systems, rivers, streams and dams has been carried out at over 30 South African gold and coal mines. @article{osti_, title = {Innovative Approach to Prevent Acid Drainage from Uranium Mill Tailings Based on the Application of Na-Ferrate (VI)}, author = {Fernandes, H M and Reinhart, D and Lettie, L and Franklin, M R and Fernandes, H M and Franklin, M R and Sharma, V and Daly, L J}, abstractNote = {The operation of uranium mining and milling plants gives rise to huge amounts of wastes.

    This chapter presents a discussion of impacts of uranium mining and processing operations on air quality, soil, surface water and groundwater, and biota. Much is already known about the environmental impacts of mining, both on-site and off-site, and that body of information provides a basis for this chapter. However, the primary emphasis of the chapter is on the unique impacts caused by.   G.M. Ritcey and V.M.

Wilton, P. Wyborn, J. Reeve. The performance of Fe(VI) was evaluated using three different synthetic effluents (solutions) and two gold mine effluents contaminated by SCN− and/or NH3-N.

Results indicated that more than 97%. This review presents a state-of-the-art of the application of advanced oxidation processes (AOPs) to some worldwide generated agro-industrial wastewaters, such as olive mill, winery and pulp mill.

natural degradation processes reduce the toxicity of cyanide over time, a passive system can be considered as a viable technology for cyanide removal from mining effluents. A pilot scale passive system has been constructed and monitored during several months in a gold mine of North-Western Spain (Asturias).

The results from this. Heuristics rules and knowledge possessed by well trained operators are put into a knowledge base through AI approach, so that a guidance output can be generated on the basis of proper judgment of pump's run/stop conditions and factors in water treatment processes (primary treatment effluent, rainwater effluent, etc.).

A number of advanced oxidation processes (AOPs) have been established for the enhanced degradation of CEC. This book chapter focuses on the occurrence and possible effects of CEC on human health and other animals. Various AOPs have been discussed in detail and their applications for the treatment of CEC have been by: 1.

For gold extraction, the most used extraction technique is the Merrill-Crow process, which uses lixiviants as sodium or potassium cyanide for gold leaching at alkaline conditions.

The cyanide ion has an affinity not only for gold and silver, but for other metals in the ores, such as Al, Fe, Cu, Ni, Zn, and other toxic metals like Hg, As, Cr, Co, Pb, Sn, and Mn.

The values in this table demonstrate the ability of natural degradationto reduce the cyanide concentration of al oxidation processes for cyanide treatment include the SO2/Air process (devel-oped by the Canadian mining company INCO) and the H2O2 (hydrogen peroxide) The Management of Cyanide in Gold Extraction The Biological Wastewater Treatment series is based on the book Biological Wastewater Treatment in Warm Climate Regions and on a highly acclaimed set of best selling textbooks.

These can now be removed in a second treatment step in which copper (II) ions are added to precipitate copper (II) ferrocyanide.

The efficiency of secondary waste water treatment is critically dependent on the separation of the supernatant liquids from the sludge. Bulking and foaming primarily make it very difficult or impossible to achieve effective separation, thus reducing the Author: Dintie Shaibu Mahamah.

In this work, the issue of hospital and urban wastewater treatment is studied in two different contexts, in Switzerland and in developing countries (Ivory Coast and Colombia).

For this purpose, the treatment of municipal wastewater effluents is studied, simulating the developed countries’ context, while cheap and sustainable solutions are proposed for the developing countries, to form a Cited by: The AA leach pad at Barrick's Goldstrike operation on the Carlin trend is probably the most sophisticated heap design in Nevada, with extensive run-on and run-off design and state of the art revegetation.

Very shortly after the cover was completed, and before plants were well established, a storm dumped inches of rain in 20 minutes. A selective roasting technique has been developed at the E1 Indio mine in Chile for the treatment of arsenic-bearing concentrates, making these materials salable.

New roasting technology will also be used at several projects under construction in the United States and Canada, with all gaseous effluents being contained in a cost-effective manner.

The authors managed to present the principles upon which various industrial water treatment practises are based, in an understandable fashion. With a broad coverage this book addresses a wide spectrum of water treatment industrial practises.
