President Steyn Gold Mine (Freestate) (Pty) Ltd (PSGM) is a privately owned mine acquired from Anglogold and Avmin (a result of restructuring within the group) and has been in operation since the early 1950's. The reduction plant currently treats between 70 000 and 95 000 tpm (metric) of ore, consisting of a blend of waste rock, clean up and underground ore. In the latter part of 1999 and in the first quarter of 2000, modifications and upgrades were implemented in the milling circuit and new technology was introduced. In short, two mills (#'s 1 & 3) were converted to fully autogenous mills (previously SAG), the mill liners were rubber injected and a third mill (# 2) was re-commissioned (also with the new liners). Three Knelson Concentrators (KC-CD20 with ICSjr) were installed, one per milling circuit. The engineering, design and project management was done by Time Mining (Pty) Ltd.
This paper focuses on the overall impact that the Knelson Concentrators (KC's) have had on the performance of the reduction plant and also has a brief look at the project financials.
President Steyn Gold Mine, Republic of South Africa - Business Day of South Africa (BDFM); South Africa's leading business daily, recently published the audited and quarterly results to December 2000 for President Steyn Gold Mine.
"Since mid 1999 management focussed on the efficiency of the President Steyn processing plant and recovery has now reached acceptable levels. The introduction and upgrading of plant and equipment, especially the Kelson concentrators and rubber liners in the mills, resulted in enhanced efficiencies increasing from 94% to 96%".
