Documented Fortran programs for ball-mill modelling

Abstract The CANMET SPOC project aims at inducing progress in process evaluation and optimization by developing user-oriented software based on state-of-the-art theory. The present work is the result of a joint effort by CANMET, Noranda Mines and Universite Laval to develop two computer packages: one (RTD) to calculate the residence time distribution that best describes the material transport through the mill, the other (FINDBS) to estimate the rate of breakage and distribution function of the population balance model in a ball mill. The RTD package can handle data from various experimental methods (impulse or complex tracer feed, with or without recycling, etc...). The FINDBS package provides options for the functional description of both model parameters B and S. The full detail of the methods and programs appears in a users guide. The program capabilities and several sample runs are presented.

Summary: New Brunswick Finance Minister John Baxter pulled something out of a hat for the mining industry in April, but there is a general concensus in the industry that he should put it back where it came from.
The industry has never been in the mood for progressive rate structures, but that is exactly what New Brunswick's 1984 budget offers to this depressed sector of the economy.

Summary: A brief outline will be given of the concept of risk and its implications with regard to investment in exploration. The relationship between risk and decisions under uncertainty will be examined as a prelude to identifying those factors which contribute to exploration risks:
consideration of the effects of corporate objectives (e.g. survival, expansion, diversification) on exploration strategy and ultimately on success or failure, exploration and mining as an investment (the relationship...

Summary: The Kudremukh Iron Ore Company Limited, a government of India enterprise, has constructed iron ore mining, crushing, handling and concentrator facilities at Kudremukh, in southwest India. Concentrate produced is pumped 65 km to dewater-ing, storage and ship-loading facilities which were built at the same time at the sea port of Mangalore.
A computer-based distributed process control system was implemented for all operations at Kudremukh and to interface with and monitor the Mangalore...

Summary: Geological exploration involves the collection and analysis of a wide variety of information. A basic problem in interpretation is to determine the interrelationships of the different data. A number of statistical methods can be applied to this problem, provided that subsets of data can be selected.
We have recently developed a set of interactive computer programs which provide the capability to quickly examine a large set of data, and may be used by people with little previous computer...
