Abstract

Mineral processing could be divided into Combination and Concentration. COMMINUTION is one of the most significant steps in mineral processing which has found wide applications in other engineering fields. GRINDING AIDS/chemicals are used in grinding circuits to change the ores breakage characteristics. Size analysis methods have important role and application in mineral processing. There are some size distribution functions to estimate size distribution such as Rosin - Ramler. In this study, the effect of GRINDING AIDS such as Sodium Tri Poly Phosphate (STPP) and (NaOH) on Sarcheshmeh copper ore and Galiran coal ore samples, were carried out by using ROSIN - RAMLER FUNCTION. The effect of STPP and NaOH on breakage parameters of Sarcheshmeh copper and Galiran coal samples had been analyzed using ROSIN - RAMLER FUNCTION.The results have shown that there was a considerable correlation between breakage parameters and Rosin- Ramler function. The changes of ROSIN - RAMLER FUNCTION coefficients can be used as a good criteria and guideline to analyze the effect of GRINDING AIDS on breakage parameters such as grind ability, mill production and fineness mean size.
