Abstract
A statistically designed, experimental study showed how gangue minerals, flux additions, fineness of grind, firing temperature, and time affect the properties of acid pellets made from a Western Australian hematite ore. Alumina has less effect than silica and lime, but interactions between the six variables occur, which influence abrasion index, reducibility, and cold compression strength. Finer grinding has little influence on reducibility but improves the other two properties. The major variable is firing temperature, which interacts with all other variables to affect pellet properties. Calculations based on the data show the implications for straight-grate pellet plants and optimum hood temperature ranges.
