The opportunities offered by an increasingly volatile world invite the
international consultant or engineering services contractor to broaden
attitudes, diversify interests, expand capabilities, retain and develop
specialist skills and base judgements upon sound principles and solid
experience. The wide-ranging scope of this review reflects such a change
but the topics of discussion are not intended to be exhaustive or to detract
from many other current developments.
The subject of environmental protection, effluent control and pollution
prevention is a primary consideration in the application of many mineral
processing technologies but is not covered here. There is an array of
developments relating to noxious gas emissions and toxic wastes and the
paramount importance of this matter justifies comprehensive conferences
dedicated solely to the application of suitable measures. This review
concentrates therefore on the main stream processing techniques for the
primary recovery of values.
