The objective is to achieve a more efficient operation and increase the production rate as well as improve the run factor. Consistent quality and maximum output with lower specific power consumption results in lower ...
Feb 01, 2019· Mine-to-mill Optimization. Author(s) W. Valery, K.A. Duffy, A. Jankovic SME Mineral Processing & Extractive Metallurgy Handbook, Chapter 3.1 February 1 2019 Abstract. A mining operation is essentially a series of interconnected processes, with the performance of each stage affecting the subsequent ones. Optimizing each stage in isolation can ...
Jul 13, 2015· Another example of Mine-to-Mill optimization is the increase of the SAG mill throughput in Porgera mine, Papua New Guinea, where by using this concept studies showed that was possible, by optimizing the blasting design, reaches up to 25% of increase in processing capacity (Grundstrom, Kanchibotla, Jankovich, & Thornton, 2001).
Jun 06, 2016· Based on experience, mill-liner designs have moved toward more open-shell lifter spacing, increased pulp lifter volumetric capacity, and a grate design to facilitate maximizing both pebble-crushing circuit utilization and SAG mill capacity. As a guideline, mill throughput is maximized with shell lifters between ratios of 2.5:1 and 5.0:1.
