Raw material Sylvite(100)% KCL Carnalite(KCL.Mgcl2.6H2O) Sylvanite(KCL . Nacl)

Two processFractional crystallization process.Forth flotation process.

Fractinal distilation Higrade grade (KCL) produce(90-99)%. Sylvinite ore use. Use unit operation process. Produce more pure. More expensive.

Forth floatation process Produce standard grade.(60)% Sylvite ore use. Use hydrometholurgical. Produce less pure. Less expensive.

AdvantageProduction cost low.Raw material are available.Healthy crops.Optimizing yield.Increasing profit potential.

DisadvantageKCL is harmful to seed.Little growing plant .Plant are very much sensitive.

By product KOH. MgSO4.Na2SO4 Bromide. Bromine. NaCl.
