The Estech General Chemicals Corporation proposes to use equipment and design generally available and practiced by the presently operating mines. The components of the operation are two large walking draglines for parallel ore extraction from two mines; hydraulic ore transportation via pipeline to a central washer for ore disaggregation and pebble recovery; a feed preparation and flotation plant for extraction of finer phosphates; wet rock storage and drying; and shipment via rail. Clay and sand wastes are to be disposed of initially in separate areas, but will subsequently be mixed into a common backfill using the method that proves to be most viable technologically and economically. The Corporation also proposes its water use plan and water management system, and the restoration of all land disturbed by the operation.
