An energy-based approach to blast design
By D. W. Taylor, I. W. Farmer, N. Mojtabai
Rittinger's and Bond's descriptions of rock crushing relate the energy input required to fracture rock and the surface energy required to form new fractures to the change in specific surface area of f

Case-based reasoning: a catalyst for improvement
By G. S. Pauley
Paper presented at a meeting on: Artificial intelligence in the minerals sector, held in Nottingham, UK, 20 April 1993 (original title: Case-based reasoning can be a catalyst for improvement). A new c

Development of a sensor to measure copper in alloys and matte
By A. J. Davidson
A Cu-conducting solid electrolyte was used to develop the sensor. Instead of measuring the potential across the electrolyte from the reference material to the Cu-containing phase, a potential was appl

Minimum recovery zone height in flotation columns from particle-bubble collision analysis
By J. A. Finch, Zhenghe Xu, Z. A. Zhou
A particle-bubble collision model was used to investigate the minimum recovery zone height, H(r,min) required for flotation columns. The criterion used to define H(r,min) is that height which gives un

Effect of ladle additions on chemical composition of metallurgical-grade silicon
By R. M. Cooper, H. K. Herbert, D. N. Phillips
A study was carried out to determine the effects of adding CaCO3, Fe, Al and CaSi2 to the ladle, rather than to the raw materials, in order to increase the concentration of Ca, Fe and Al in the final

A methodology for the statistical and spatial assessment of soil contamination around mining districts
By S Durucan, A Korre
The application of simple methods of statistical analysis, coupled with geostatistical analysis and geographic information systems, can only summarise and give an outline of the spatial distribution o

Recycling of spent Denox catalysts
By M. Foguenne, A. van Lierde, P. Henry
Leaching experiments were carried out on a spent catalyst sample with a honeycomb structure, containing 47.5% Ti, 5.8% Mo, 2.7% Si, 2 035 ppm As, 52 ppm Pb and 8.8 ppm Hg. More than 93% of the Mo and

Distribution and genesis of some epizonal Zn-Pb and Au provinces in the Carpathian-Balkan region
By A. H. G. Mitchell
Most, if not all, of the six recognised post-Cretaceous, predominantly andesitic mineralised belts in the region are now thought to be subduction-related magmatic arcs. The Inner Carpathian arc and th

Earthing practice in metalliferous mining: results of study at Mount Isa mine, Queensland, Australia
By R. Sankey, L. Gatty, F. Bizzozero, G. F. Shannon, F. Savaglio, L. McDonald
State mining regulations in Queensland stipulate that a mine be provided with an earth installed on surface and that all underground equipment that needs to be earthed should be connected via a copper

A future in coal: viable or not?
By G. Kill
Although other energy commodities have developed successful futures contracts, long-term contracts still dominate the coal market. To establish whether coal markets will develop in the same way, coal

Processes for reducing zinc from slags using on iron-carbon melt
The reduction of zinc from slags by a molten, carbon-saturated bath was examined in a laboratory study under conditions of continuous slag feeding. The results show that it is possible to reduce the b

High-temperature mine climate simulation model for predicting the effect of mine fire
By P. Mousset-Jones, G. Danko
Variations of the temperature and steam/moisture content of the air with distance and time are modelled for a single airway. The input for the simulation is an air temperature that varies with time, t

Role of diethylene triamine (DETA) in pentlandite-pyrrohitite separation: part 1: complexation of metals with DETA
By S. Kelebek, J. A. Finch, Zhenghe Xu, S. R. (Ram) Rao
To improve SO2 emission compliance, pyrrhotite from Sudbury copper-nickel ores is being depressed with DETA. To understand the mechanism of depression, the role of complexing in controlling metal-ion
