Sources Of Construction Aggregate

Many sources of waste rock are geologically similar to natural sources of construction aggregate, and, therefore, can be crushed and/or screened using conventional aggregate processing equipment. Waste rock from iron ore or taconite processing may be heavier than conventional aggregate. Mill Tailings.
