Continuous Mining Cutter For Phosphate Rock Phosphate mining in the United States Wikipedia. In 2015, 27.6 million metric tons of marketable phosphate rock, or phosphorite, was mined in the United States, making the US the worlds third-largest producer, after China and Morocco.The phosphate mining industry employed 2,200 people.

2015-9-10 reacted with ground phosphate rock in a cone mixer. The resultant slurry begins to solidify on a slow moving conveyer en route to the curing area. At the point of discharge from the den, the material passes through a rotary mechanical cutter that breaks up the solid mass. Coarse ROP-TSP product is sent to a storage pile and cured for 3 to 5 weeks.

2012-1-10 Triple Superphosphate (TSP) As in the case of SSP, the rock phosphate is ground to a fine mesh and reacted with concentrated phosphoric acid (52 to 54% P 2 O 5) in a cone mixer: C a 10 P O 4 6 F 2 + 14 H 3 P O 4 → 10 C a H 2 P O 4 2 + 2 H F. It is then fed to a continuous den and piled for curing.

2018-1-4 A. Abutment - In coal mining, (1) the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and (2) the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.
