Characterisation of Iron ore and Manganese for resource optimisation

Date: 15 April 2021
Venue: Zoom
Time: 11:00 – 12:00

About the presentation:

Characterisation of a mineral resource is the first step in determining the potential product grade and product mass recoveries as inputs to the process design.
 
It is therefore critical that the characterisation data achieved is representative of the resource and in line with the plant production technologies to be utilised.
 
Different techniques are applicable as the ores move through the various characterisation stages. The presentation will focus on the techniques relevant to beneficiation of the ores using dense medium technology.

About the speakers

Pieter Pieterse
Metallurgical and Process specialist – Various Commodities

Pieter has extensive experience (30 Years) in various commodities namely Steel making, Iron ore (hematite and Magnetite), Coal, Lead, Zinc, coper, dolomite, gold and heavy minerals. His main work functions are; Lead process engineering, plant metallurgist and Plant/Production manager.

Pieter currently operates as a Metallurgical/Processing specialist on Iron Ore, Diamonds, Gold, HBI and chrome projects.  The main aim of the projects is to improve production performance and to generate the required characterisation data for study completion.

Jeremy Bosman
Principal Process Consultant

After graduating, Jeremy Bosman started work at ISCOR. He worked at both the Pretoria and Van der Bijl Park steel works. Jeremy, left ISCOR to make cement for a couple of years at Blue Circle Cement in Lichtenburg.

In 2003 he founded PESCO (Process Engineering Solutions Company), a consulting company offering services to the minerals processing industry. At the same time Jeremy started lecturing part time in minerals processing at Pretoria University. This lasted 10 years and courses were presented at both undergraduate and post graduate levels.

PESCO has grown from a consulting only company to include a dense medium testing facility. This includes both a laboratory, where medium characterisation is done and a pilot plant. The pilot plant has a 610 mm WEMCO design drum, 165 and 200 mm cyclones and a vibrating screen for determining drainage rates. Ores with sizes ranging from 40 to 0.3 mm and medium densities ranging from 1.3 to 4.5 t/m3 have been tested on the pilot plant. Commodities include iron ore (South African, Australian and Indian), lithium (Australia, Zimbabwe), coal, base metals including lead/zinc and tin, platinum and diamonds.
