Quarry Fines?
Dear P2Tech:
Glasgow Quarries in Southeast PA generates "fines" from the cleaning
operation of their crushed product. Approximately 98% would pass a 20 mesh
sieve. Analysis indicates approximately 50% calcium carbonate, 40% magnesium
carbonate, 5% insolubles and the remaining 5% silica, iron, and aluminum
oxides.
The fines are currently being stockpiled for agricultural use. Glasgow
markets the fines through a sales agent that has exclusive rights for
agricultural uses.
The Quarry is looking for other outlets for this material. I
directed
him towards the Bureau of Abandoned Mine Reclamation, Bureau of Water
Quality -
sludge applications, and TSD's that might use fines in hazardous waste
stabilization. Is anybody familiar with any other sources and/or uses? Any
suggestions would be greatly appreciated.
