Analysis by chemical potential diagram of the oxidation of molten silver selenide
By G. G. Barbante
An understanding of the thermodynamics of smelting copper anode slimes is a prerequisite for improvements to the process. During slimes smelting, a silver-copper selenide matte is formed and subsequen

Mechanical properties of three Australian iron ores
By M. V. Swain, N. Bristow, R. D. Dukino
During mining, crushing and handling the size of iron ore lumps decreases. Key factors in determining the amount and size of fines that are produced are the mechanical properties of the ore. In a cont

Influence of material properties on high-temperature zone reactions in sintering of iron ore
By L. T. Matthews, C. E. Loo, R. P. Williams
The behaviour of iron ores and fluxes in the high temperature zone of a sintering bed is extremely complex. Following a review of current knowledge, an attempt is made to define relevant terminology t

Hydrothermal alteration associated with sediment-hosted Rooiberg tin deposits, South Africa
By J. E. Misiewicz, A Rozendaal
Paper presented at Geofluids '93, held in Torquay, UK, 4-7 May 1993. The tin field consists of a fragment of Lower Proterozoic volcanosedimentary rocks surrounded by granitoids. Almost all the signifi

Recovery of phosphate values from, and flocculation of, phosphatic clay waste from Abu-Tartur, Egypt
By M. K. Abd El-Rahman
A complete chemical analysis of the waste showed that it contains 15.64% P2O5; X-ray diffraction analysis revealed that it is composed mainly of francolite, calcite, pyrite, quartz and dolomite. The p

The only way is up
By G. Richards
Research shows that having more women in the top mining jobs can bring bottom-line benefits. Mining companies are starting to embrace the need for greater gender diversity at board and senior manageme

Selective chlorination of iron from synthetic pseudobrookite
By F. C. Gennari, D. M. Pasquevich
With the gradual exhaustion of natural rutile, there has been extensive research into its synthesising from lower-grade titanium minerals. The removal of Fe from pseudobrookite (Fe2TiO5) by chlorinat

Layered mine waste co-mingling for mitigation of acid rock drainage
By J Hadijigeorgiou, R. W. Lawrence, R Pouling
The layered co-mingling method involves the disposal of waste rock with the addition, at predefined construction stages, of layers of dewatered mine tailings. The resulting waste structure displays bu

Trace-element geochemistry and alteration facies associated with epithermal gold-silver mineralization in the evolving volcanic centre, Rosita Hills, Colorado, USA
By C. J. A. Mcewan, C. M. Rice
The Rosita Hills contain rich, vein- and breccia pipe-hosted precious metal deposits. Volcanic activity occurred in two cycles - an early, mainly andesitic cone-building phase that terminated in the f

Laboratory technique for evaluation of methods of suppressing nuisance dust
By S. P. Godby, S. P. Sharples
Wind-tunnel tests were carried out of the conditions under which nuisance dust particles (100-1 000 micrometres) become entrained by wind. A laser entrainment monitoring system (LEMS) was used, and wa
