User:Kamikokokokoko/The phosphorite deposits of Zhanatas

The phosphate Deposit Zhanatas is located 20 km South-West of the city of Zhanatas Sarysu district of Zhambyl region. The field was discovered in 1935 and has been in operation since 1964.

Geological structure
The phosphorite deposits of Zhanatas is the place to review the deposits of the lower Cambrian. Phosphorite horizons of this Deposit are located on the North-Eastern wing of a large asymmetric layer. This structure, crossed by a large zonal explosion, reaches from 30°(in the North-West) to 75°(in the South-East), was cut by small explosions of different directions.

The nature of the blackout
The concentrated ore horizon consists of phosphorites and phosphorite conglomerates, phosphorite and siliceous shales, phosphorite Dolomites containing layers of phosphorite juices. There are two phosphorite horizons, the average thickness of the lower layer is 7.5 m, and on the upper-18 m. These two layers are separated from each other by a phosphorite-shale layer with an average thickness of 18 m. the structure of phosphorite is crystalline, hidden crystalline, granular, oolite. The average size of the P2O5 in the ore ranges from 15-17% to 35%. $ 84 million a year. the South-Eastern and Central phosphorite quarries were put into operation in 1975, the North-Western quarry was put into operation after 1980. Here phosphorite is used to produce yellow phosphorus, thermal phosphoric acid and phosphate rock.
