  • Mine-To-Mill Optimisation: Effect Of Feed Size On Mill

    Over the past 15 years, mine-to-mill studies have focused attention on the impact blast fragmentation has on concentrator throughput. Blasting provides the first opportunity for comminution or size reduction. It is also a cheaper and more efficient process, compared to both crushing and grinding.Mine to Mill 2020 Advanced Mine to Mill Optimisation,In the late 1990's, researchers at the University of Queensland have proposed a concept popularly called "Mine to Mill Optimisation" and demonstrated that all the processes in the mine to mill value chain are inter-dependent and blast fragmentation (or particle size distribution) play a critical on downstream processes especially on the downstream AG/SAG mills.

    Mine-mill reconciliation is the term applied to the area of comparing, balancing and adjusting production estimates between mine and mill for consistency in reporting, and this thesis seeks to evaluate the concerns in this area and to find robust strategies to ameliorate these concerns. A review of metal accounting and mine-mill reconciliationRing Blasting Mine to Mill Optimization Benjamin Cebrian,Mine to Mill optimization without the mill A series of stopes of the hardest ore were selected to perform a mine-to-mill program by increasing fragmentation through higher energy blasting. Consequently, powder factor and energy factor were increased by 30% from about 1000 kJ/t up to 1400 kJ/t, depending on geological domains.
