    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

    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

    Achieving profitability from mechanisation of Underground in India

    By Z Hu

    The technique of reclaiming disturbed land by use of a hydraulic dredge pump (HDP) (which is a set of hydraulic machines for earthwork), termed 'digging deep to fill shallow has been used in the recla

    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
