Review of Operations" Technology Division . . .(continued)Technology DivisionConcentrator process control studies are now being done at the ARC site; it isplanned to equip the facility to allow control optimisation of new plants to bedriven from this central point. Plans to incorporate on-line chemical analysisand other process parameters in control loops have been brought forward andthere is a full supporting research programme directed towards the on-lineanalysis of feed and tailings samples.The pilot plant for the <strong>Anglo</strong> <strong>Platinum</strong> Converting Process has continued toprovide valuable information to assist in the design of the full-size installationnow under construction at Rustenburg. Control strategies and limits of feedmatte composition are among the issues that have been investigated.Fundamental studies of furnace slag composition and fluxing requirements arebeing carried out within a collaborative research programme using facilities inMelbourne.Support for the phased expansion of the refining of base metals and platinumgroup metals embraces work at ARC, the Johnson Matthey Research Centreand universities in South Africa and Europe. Related studies are beingconducted with <strong>Anglo</strong> <strong>American</strong> Research Laboratories for a broader range ofbase metal applications.Mining technology<strong>Anglo</strong> <strong>Platinum</strong>’s efforts in the area of mining technology are mainly directedat achieving significant increases in profitability by optimising technology forthe mining of narrow seam UG2 Chromitite Reef.A suite of appropriate technology is being implemented on both existingmines and new mining projects. The areas concentrated upon include:● Stope drilling, blasting and cleaning● Stope mechanisation● Stopeface rockcutting● Rapid development advanceAchieving a quality daily blast remains a priority, and to this end a miningoptimisation project is under way. The goal is to improve face advance perblast and a reduction in lost blasts on a Group-wide basis by applying the bestmining practices as identified at a pilot site.Instrumentation workshop64
