On the other hand, there was such a rapid implementation of the high gravity centrifuges in the gold industry to the point that some projects were executed without proper assessment of the applicability of the technology to the feed being processed.<br /><br />Having only general familiarity for the cement industry I can imaging that rapid implementation of HPGRs throughout this industry was due to very tangible benefits. The feedstock for all cement plants is essentially the same and there is also great similarities for the process flowsheet. Measureable OPEX cost reduction (power, wear parts, optime) appears to have been the driver.<br /><br />In the case of high gravity centrifuges in the gold industry, the feed stock contains some coarse grained metallic gold (gravity recoverable) or none (refractory gold ore). Once the distinguishing key parameter for successful implementation was identified, then it became a matter of fact.<br /><br />Maybe if there is another example of technology which rapidly spread to a segment of the mining and minerals industries one could identify if there is a trend?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-1458068945913793462.post-67276900701312827882010-10-06T20:41:44.248+01:002010-10-06T20:41:44.248+01:00Hi Michael, interesting blog.

You make many good points but in the case of HPGR there are many hurdles to be overcome including that, for example, it is often more capital intensive and more difficult to operate than SAG based technology and there needs to be a significant operating cost savings to achieve reasonable payback. For many ores it isn't there.
