Multicomponent AG/SAG mill model ScienceDirect
2013年4月1日 1 Introduction The Runofmine composition strongly affects autogenous mill operation However, the effects of a varying ratio of hard and soft components in mill performance are not described by the current generation of AG/SAG models (Stange, 1996)For example, current JKSimMet models (NapierMunn et al, 1996) assume a uniform feed, and describe it purposes, SAG mills utilise a combination of steel balls and coarse ore to achieve the desired discharge particle size [2] An essential performance metric for a SAG mill is its throughput, which measures the volume of processed ore per hour [3] SAG mill throughput maximisation stands as a critical priority, given its profound financial outcomesA Hybrid Intelligent Framework for Maximising SAG Mill However, ore below the pay limit adds variation to the mill grade as increased mill throughput will be required to make up for the loss of gold, and that impacts on the recovery in the plant It is against these perspectives and findings of this study that the MCF should be seen as a method that identify the real problems underground and when these are addressed, the profitability of Monitoring ore loss and dilution for minetomill integration in 2022年6月6日 This paper describes the adopted approach for increasing the capacity of an existing industrial grinding circuit by adapting the respective configuration to process the ore from a new mine Accordingly, due to Sossego mine exhaustion, Vale S A decided to use the existing industrial facilities and infrastructure for processing the Cristalino ore deposit located in Para PreProcessing to Increase the Capacity of SAG Mill Circuits
