Mining and quarrying wastes: A critical review
网页1988年2月1日Abstract. Mining and quarrying wastes pose problems of environmental pollution. To prevent this, uses must be found for these wastes. The purpose of this stone is to review the availability, distribution and uses of wastes from most mining countries of the world. Some of the uses identified for the waste materials are as concrete aggregates for
