Main industrial indicators of gypsum deposits
1. General industrial indicators:
Layered gypsum , anhydrite deposit, 55% minimum commercial grade (CaSO 4 • 2H 2 O + CaSO 4 ). The thickness of the exposed mining is ≥2 meters, and the pit mining is ≥1 meter. The thickness of the stone is removed; the exposed mining is 2 meters and the pit mining is 1 meter.
Fiber gypsum deposit, 95% of the lowest industrial grade (CaSO 4 • 2H 2 O). The lowest line has a ore content of 14%. The minimum thickness of the single layer (pulse) of the fiber gypsum is 2 cm, and the thickness of the mined body: pit mining ≥1.7 m, the thickness of the stone is removed, and the pit mining is 1 m. Fiber gypsum and layered gypsum, anhydrite deposit, fiber gypsum CaSO 4 •2H 2 O content is 95%, layered gypsum, anhydrite CaSO 4 •2H 2 O+CaSO 4 content is 55%, line mineralization rate is 14% The minimum recoverable single layer thickness: layered gypsum, anhydrite is 10 cm, and fiber gypsum is 2 cm. Available thickness: pit mining ≥ 1.7 meters, the thickness of the stone removed is 1 meter. The Juyi Weijing gypsum deposit in the loose layer has an industrial grade (CaSO 4 • 2H 2 O) of 85%, and the lowest minable stone contains a giant pegmatite rate determined according to the ore dressing test. Available thickness: exposed mining ≥ 2 meters, stone removal thickness: exposed mining > 2 meters.
