Chadormalo iron ore selection and breakage functions
Chadormalo mine is one the most significant iron mines in Iran which its products is used in steel making factory. A mineral processing plant with three semi-autogenous (SAG) mills, 9.7m in diameter and 4m in width, produces iron concentrates using Chadormalo ore. Each SAG mill has about 400t/h capacity which a gyratory crusher feeds them. The aim of this project was to estimate the breakage
