Significant Risks and Mitigation

  • Delayed Relocation: Negotiation at advanced stage, Plan

B in place.

  • Lightning: Advance warning systems.
  • Slope Stability: Radars etc
  • Trackless Mobile Machinery: Collision Avoidance System.
  • Blasting/Explosives: Electronic detonators etc.

Overview

  • Biggest single stream Platinum Concentrator in the World

(600ktpm).

  • Decision to build a single stream plant required some ground-

breaking technology…..

  • First:

– HPGR installation for a platinum ore body – Gearless drive mills in Anglo Platinum

  • Biggest:

– Primary Gyratory crusher 60’’ with a 1000kW motor – Ball Mills in the world 26’ø x 37.6’ EGL with 17.5MW gearless drive – Centrifugal blower installation in Africa – Mill discharge pumps in SA – 1,45MW motors with gearbox drive – HPGR in Africa with the largest installed power in the world (2 x 2.85MW)

Energy Efficient Design

  • Ultra high rate thickeners for tailings disposal
  • High efficiency motors installed

– More work per unit of electricity consumed

  • Day-night switches for lights
  • “Ready to float” material can bypass primary milling stage:

– Creates additional primary milling capacity or save energy on primary milling stage – No energy waste to pass sufficiently liberated material through primary mill (incl. metallurgical benefits)
