An African Rare Earth Story

Presented by Derick de Wit, Associate Director | Mining Advisory, Venmyn Deloitte

Date: Thursday 20 October 2016
Time: 17:00 for 17:30
Venue: Worley Parsons, 39 Melrose Boulevard, Melrose Arch

REEs are a common term describing the 15 chemically similar lanthanide elements which appear together at the bottom of the Periodic Table. Two other elements, yttrium and scandium, have similar chemical properties, and are often also referred to as REEs. REEs can be divided into “light” and “heavy” REEs.

According to the U.S. DoE, “critical” REEs refers to “the stuff you need the most but can’t get enough of.”

All the REEs have very exotic names:

  • lanthanum (La)
  • cerium (Ce)
  • praseodymium (Pr)
  • neodymium (Nd)
  • promethium (Pm)
  • samarium (Sm)
  • europium (Eu)
  • gadolinium (Gd)
  • terbium (Tb)
  • dysprosium (Dy)
  • holmium (Ho)
  • erbium (Er)
  • thulium (Tm)
  • ytterbium(Yb)
  • lutetium (Lu)
  • yttrium (Y)

Realising the productivity potential of Joy Continuous Miners in Underground South African Coal Mines

Presented by Dean Hoare , Mining Productivity Consultant, Joy Global

Joy Global is continuously pursuing the optimal performance of their equipment fleets in the underground South African coal mining environment. Joy equipment manufacturers around the World will say that ‘all Joy Continuous miners are created equal’ Yet in the field, many CMs underperform against their design potential. We explore why there is such variability and how CM mining practices, machine tune -up and ‘JoySmart Solutions’ enables us to unlock the production potential.

The presentation describes the recent developments in the use of real time equipment data acquisition and analysis, monitoring of improvements in equipment productivity and utilisation, outlining the key performance drivers necessary for mechanised coal mining equipment to be optimally managed and implemented.

About the presenter: Dean is a mining engineering graduate of Trent University (UK) and UJ, Registered with ECSA and a member of the SACMA and SAIMM. He has over 30 years’ experience in the South African Mining Industry.  Dean has held senior managerial positions with a major South African Mining Company and currently works with Joy Global as a mining productivity consultant. Dean is passionate about  achieving the goal of sustainable safe and productive underground coal mining in South Africa.
