Mineralogy of platinum group elements in the Kambalda nickel deposits, Western Australia
By D. R. Hudson, M. J. Donaldson
"Study of gravity concentrates from the gold-recovery circuit of the Kambalda nickel mill has enabled an assessment to be made of the nature, relative abundance and compositional variability of platin

Thermodynamics of FeO-MnO-TiO2 melts saturated with iron at 1475 degrees C
By H. B. Bell, L. C. Smith
Measurements have been made of the activity of 'FeO' in 'Fe0'-Mn0-Ti02 melts at 1475 degrees C. The results obtained are discussed in terms of ideal mixing of titanates and in terms of a regular solut

Bayesian approach to slope stability assessment by updating probability of failure treated as a random variable
By N. Powell, R. J. Pine
An algorithm is proposed for updating the probability of slope failure on the basis of sequential testing using Bayesian probability theory. The approach is novel and computationally straightforward s

Simulation of grinding circuit at Gumuskoy silver plant, Turkey
By B. Sonmez, B. Aksanl, S. Ersaym, I. F. Erkal, S. L. Ergun
The comminution circuit at the plant has experienced severe problems arising from a feed containing much larger amounts of clay and having a higher moisture content than expected. Three solutions were

Broken Hill area, Australia, as a Proterozoic fold-and-thrust belt: implications for the Broken Hill base-metal deposit: contributed remarks; authors' reply
By A. L. W. Lips, B. P. J. Stevens, T. J. R. Barclay, E. Rothery, S. H. White
Discussion by B.P.J. Stevens of the paper, published in Trans. IMMA, vol.104, 1995, p.B1-B17, is presented together with the authors' response. Stevens questions the authors' radically different inter

Nickel sulphide mineralization in the lick fork prospect, Virginia, U.S.A.
By K. C. Misra, W. Wrightson Jr.
The Lick Fork prospect shows appreciable nickel sulphide mineralization in a narrow, steeply dipping, layered sequence of metamorphosed hornblende peridotite, gahhro and hornblende gahhro, intrusive i

The case for continuity in extractive metallurgy (the eighth Sir Julius Wernher memorial lecture of the Institution of Mining and Metallurgy, delivered in London, 4 October 1971, at the symposium on Advances in extractive metallurgy and refining)
By J. H. Chesters
The main, though rarely mentioned advantage, is likely to be the standardisation of best practice and product. In a batch process conditions vary cyclically, but with a continuous process they would,

The sinking and equipment of a circular shaft
Paper presented at the Mining Institute of Scotland's annual general meeting held in Glasgow, 8th April 1916. Although there is nothing novel or difficult about the sinking described, circular shafts

Refinements of model for economic evaluation of preconcentration
By R. J. Gochin, P. Bevilacqua, G. D. Schena
This class of flowsheet-dependent simulators does not replace modular simulators, such as Modsim and Microsim, which are necessary for the assessment of different flowsheets before selection of the mo

Geophysical exploration for nickel sulphide deposits in the Yilgarn block, Western Australia
By D. J. Esdale, D. F. Pridmore, F. W. Lindman, J. H. Coggon
Almost all the presently viable nickel reserves in the Yilgarn Block contain nickel in a sulphide phase. Both volcanic peridotite- associated (VPA) deposits and intrusive dunite-associated (IDA) depos

Computers and blasting
By T. J. White, R. A. Farnfield
Early computerised blast monitoring equipment consisted of a digital version of the existing analogue machines with, perhaps, a few enhancements. Many additional facilities have since been developed t

Aspects of nickel metallogeny of Southern Africa
By E. C. I. Hammerbeck
"Geological controls and constraints in space and time define the milieu of the nickel deposits of Southern Africa. Primary, magmatic deposits are of two types, e.g. synvolcanic or syntectonic deposit

The suppression of dust in coal-mines of Great Britain -thirty-second report to the committee on the control of atmospheric conditions and spontaneous combustion in mines-
By J. Ivon Graham, T. D. Jones
This paper presents methods in use in British coal-mines for the suppression of dust. While the effect of present-day treatment will not be apparent for several years, in pits in South Wales, concentr

Blasthole stoping - drilling accuracy and measurement
By F. Boudreault, M. J. Scobie, J. Szymanski, C. Hendricks
The development of new stoping methods and more effective control over dilution, recovery and fragmentation depends on improved accuracy in blasthole drilling. The mechanisms and factors which control
