(PDF) Quarrying Economics Emmanuel Igonor -

ASSESSMENTS AND CHALLENGES IN QUARRY OPERATIONSFor a successful quarry development, two basic stages are involved (Keith, 1991): (a) the investigation (pre-production) stage and (b) the production stage. For ease of discussion, the cutting or crushing and screening of stones into various sizes are all here considered under the production stage.

Manufactured Aggregates – TREMS

Quarry aggregate reserves are depleting rapidly, particularly in some desert regions of the world. Worldwide Quarry aggregate production is about 4.5 billion tonnes, and Australia alone consumes about 130 million tonnes of aggregates annually. Moreover, the production of 1 tonne of natural crushed aggregate emits 7.4-8.0 kg of CO 2.
