The course will provide deeper insights into the comminution process and practical process improvement tools and methods that were introduced in the Advanced Mine to Mill courses. Two intensive days of 6 hours from 4-10pm will provide considerable opportunity to upgrade skills specific the crushing, milling and classification that you can link into the overall mining process chain opportunities taught in the Adv M2M courses.

DEJANOS TUS COMENTARIOS

Areas we will present include:

  • Influence of ore variability on mill and circuit design – the Integrated circuit.
  • Insights into particle motion in mills.
  • Transport in mills: slurry pooling, discharge design.
  • Mill liner design guidelines and overview of assessment.
  • Collecting and Using survey data for Circuit optimisation.
  • Practical crusher operation.
  • Pre-crushing feed to SAG mills.
  • The key role of classification in circuit productivity.
  • Process control, Lag time for feed rate and load interaction, grindcurves.
  • Controlling the Dynamic Behaviour of the Mill.
  • Fully utilising the capability of recycle pebble crushing.
  • Milling and crushing tools: on-line mill filling, liner monitoring, crusher control, cyclone control.
  • SAG milling opportunities.










Prof. Malcolm Powell

Director of Liner Design services, Comminution & Transportation Technologies Inc. & Comminution Reimagined ltd

Prof Powell has applied fundamental comminution research to design and process improvement on over 60 mines worldwide during 35 years at Mintek, UCT, and then as Professor of comminution at the JKMRC in Australia. His work is published in over 200 papers and has been presented in as many conferences worldwide. Malcolm collaborates extensively, with close compatriots on 5 continents forming the Global Comminution Collaborative (GCC) – providing an expert research and consulting base covering the full comminution process chain. Malcolm provides on-site experiential training and site reviews to empower mine staff to upgrade the productivity and their skills. This is supplemented with formal training workshops on liner design, comminution and Advanced Mine to Mill. Malcolm’s research vision is of integrated total process simulation as a tool for innovation – linking geology, mining, energy and size reduction, gangue rejection and recovery into flexible process design and process optimisation. Malcolm Runs three companies dedicated to advancing cutting edge technology into the mining industry, plus supervises research students.

Experience includes acting as an industry consultant called on by the major mining companies on 5 continents. Prof Powell’s industrial applications have delivered direct benefits to production revenue total in the hundreds of million Dollars.

Recent process reviews: In 2019 demonstrated and provided the technical pathway to increase production by between 10 and 20% on three mines (Las Bambas, Peru; New gold and Voisey’s bay, Canada). At the Barrick Cortez demonstrated a 16% increase in mill throughput capacity (Powell et al. AusIMM mill operators conference 2018 and SAG conference 2019), and again in 2020 for a new ore body. Anglo American Platinum Mogalakwena crushing circuit: capacity increased by 20% based on recommendations of a GCC review and simulations, worth about $100M per annum (Powell et al, SAG conference 2011). Increased mill throughput at Cadia of 10% over a period of liner life, translating to 3% over liner life, a value of over $20M per annum (Bird et al., SAG conference, 2011). Navachab Ball scats removal: a step change of 9% in mill throughput (Powell and Smit, SAG conference 2001), which drove an industry-wide upgrade to grinding ball quality in Southern Africa.

Liner design: Increases in liner life of over 50% on many mills, worth $0.3-1.5M per annum on single mills. Liner redesign Pustynnoye mine, Kahzakstahn: increased liner life by 50% and mill throughput by 20% (Powell et al, AusIMM.MillOps, 2018).

MillTraj liner design software: with over 200 licences with half the world liner suppliers the use of this software has propagated liner life and mill performance improvement worldwide.
