Evaporite Potash Ore

Potash ore is extracted from two major ore deposit types, deeply buried marine evaporite deposits that typically range from 400 metres to greater than 1,000 metres below the surface, and surface brine deposits associated with saline water bodies such as the dead sea in the middle east and the great salt lake in north america.

Waste disposal problems near potash mines in Saskatchewan

An attempt is made here to synthesize the waste disposal problems of the potash industry in the Province of Saskatchewan, Canada. The problems are related to the type of ore mined and to the environment in which the waste disposal basins are situated. Ten mines are at present mining potash in the Devonian Prairie Evaporite Formation in

GEOLOGY OF THE TENTH POTASH ORE ZONE: PERMIAN SALAD0

The Tenth potash ore zone is a bedded evaporite deposit in the Permian (Ochoan) Salado Formation in the Carlsbad district, Eddy and Lex counties, New Mexico. The rocks of the Tenth ore zone were precipitated in the super- saline part of the Permian basin and range from 6 to 10 feet (1.8 to 2.1 meters) in thickness.
