Uzkimyosanoat (Uzbek chemical industry) state joint-stock company will modernize Samarkandkimyo (Samarkand chemical plant) JSC in 2007/08, according to Uzbekistan Today information agency.
The implementation of project is a basic part of wide-scale program on increasing the output and export of phosphor fertilizers in Jeroy-Sardarin deposits by 2010.
The project ensures organizing the industrial production of new nitrate-phosphor-calcium fertilizers (nitrocalciumphosphate) by late 2008, using nitrate acidic processing method of unfortified Jeroy phosphorites in this enterprise having capacity of 34,000 tonnes (100% nutritive materials) a year.
Specialists conclude that nitrocalciumphosphate is an effective fertilizer because it contains nitrogen and phosphate as well as calcium oxide, a compound that is efficiently assimilated by plants, calcium nitrate. The advantage of new technology is that phosphorite raw of nitric acid is used instead of deficit sulfur acid and extraction of phosphor gypsum as a waste is prevented. Uzkimyosanoatinvest Institute developed the feasibility study of the project.
In February this of year President Islam Karimov approved the program on increasing the output and export of phosphate fertilizers in Jeroy deposit (Central Kizilkums) by 2010.
The program ensures development of prospecting capacity of the Kizilkum phosphorite complex that is developing the Jeroy deposit and modernization of chemical plants manufacturing phosphorite fertilizers.
According to Uzkimyosanoat, the program is financed, using the funds of state budget, Fund for Reconstruction and Development of Uzbekistan, foreign credits and investments and own funds of Uzkimyosanoat.
In general the program foresees to develop processing capacity of Kizilkum phosphorite combine, leading processing deposit and modernization of chemical plants that are producing phosphoric fertilizers.
In the near five years Uzbekistan aims to expand phosphorite output from 860,000 tonnes to 1.2 million tonnes a year that will allow producing 400,000 tonnes of washed and fired concentrate, 200,000 tonnes of of dried concentrate, and 200,000 tonnes of phosphoric flour.
As a result of increasing the output of phosphor raw in this deposit and modernization of chemical plants, total output of phosphorite fertilizers must increase by 2010 up to 169,000 tonnes against 100,300 tonnes of 2005 including its export from 9,000 to 35,000 tonnes by this period.The resource basis of the Kizilkum phosphorite complex is the Jeroy-Sardarin deposit in the Central Kizilkums having reserves of 303.6 million tonnes and 57.7 million tonnes phosphor raw which must satisfy the demand of agricultural sector for phosphor fertilizer for more than 100 years.
