Özet

In the present study, aimed at the production of phosphate compounds, the optimum process conditions were sought for the dissolution of phosphate rock from the Mardin-Mazidaǧi concentrate. The dissolution of this phosphate rock in aqueous solution saturated with a mixture of Cl2-SO2 gases was optimized by passing Cl2 gas through the final solution. Reaction temperature, solid-liquid ratio, Cl2 gas flow rate, reaction period and stirring speed were employed as parameters. Using the Taguchi Fractional Design Method, it was found that the optimum process conditions, at which 93.35% P2O5 conversion was reached, were as follows: Reaction temperature: 20°C Solid-liquid ratio: 1/7 (w/v) Cl2 gas flow rate: 120 cm3 min-1 Reaction period: 20 min Stirring speed: 600min-1.
