The Aggregate Mining Process. Aggregate mining in New York takes two forms. The simplest process involves sand and gravel excavation. Sand and gravel are unconsolidated minerals that can be mined using a front-end loader or excavator then processed through crushers and screens to make the desired end product. Excavator removing sand and gravel.


Aggregates must have predictable, uniform, and consistent materials properties. They must be dry and clean before they can be used. Aggregates are only as good as their processing. They are mined, crushed, washed, and separated. The successful outcome of each step, the processing of a good aggregate, depends on the success of the previous step.
