Khuor Playa with an area of 2,250 square kilometers in the lowest altitude region of the catchment area of the city of Khor, due to the entry and evaporation of surface and underground waters, and thus sedimentation over several thousand years, has resulted in the formation of a porous salt shell with an area of 1300 Kilometers square and a thickness of more than 8 meters, in which about 1 billion cubic meters of brine with salinity of 320 g / L contains valuable salts and among 60 pleasures of Iran, the highest grade of potash is known and is considered by the mining sector Country is located.
Based on this, in the years of 75 and 76, performing special exploration and environment-friendly operations, extraction and exploitation of the mines are estimated to be cost-effective, and after that, the operation of equipping has begun immediately.
In fact, it is possible to exploit the saline playa through drainage which can be achieved through the digging of the canal and the well and the ditch. Therefore, considering the thickness of the juice layer and the conditions of the extraction blocks, it is necessary to select each of the fields, such as the drill or facial channel Accepts .
From 78 to 96 years, in 7 separate phases, a total of 45 km of canal and 29 wells and 5 wells were excavated for exploitation and extraction of salty in Playa.
In addition to the exploration of Playa, from the years 75 to 96 nearly 300 loops of exploratory boreholes have been excavated and studied.
The average salinity of salinity is estimated to be 1.22 g / cm3, and the level of saline staining in the salt shell is 30 cm above the surface of the earth, and usually after rising, the level of the stack increases to such an extent that it leads to formation in a season.
On average, 200 kg of salt and 6 kg of potash can be extracted from each cubic meter of saline barley, while in the process of extraction of potash, other side products such as magnesium and calcium compounds can also be processed.
According to the plan, 15 million cubic meters of saline should be collected and discharged annually in Playa and transferred to the solar evaporation pools through a pumping station and a pipeline of about 10 km.
