Special Report: Test work of Mt Kokeby ore continues to return excellent results for Red Mountain with an optimum result of 96 per cent recoveries for a 37 per cent alumina product.

The evidence continues to mount for the DSO potential of Red Mountain Mining’s (ASX:RMX) Mt Kokeby kaolin project in Western Australia with the latest test work indicating that recoveries of more than 96 per cent are achievable.

DSO refers to “direct shipping ore” – namely, minerals that require only minimal processing such as crushing before they are exported, which keeps costs low.

Red Mountain noted that attritioning tests carried out to optimise both the alumina grade and recovery to finer size fractions had an optimal result of over 96.8 per cent recovery for a product with more than 37.5 per cent aluminium oxide (Al2O3) content that reports to a size of 53 microns.

This improves on previous testing at the 75-micron mesh size, which achieved alumina recoveries ranging from 87.8 to 99.4 per cent at an average grade of 36.9 per cent Al2O3.


The absence of the market to react to this promising project is about the timing and trimming of the amount of time that’s required in placing funds to suit a substantial rise in SP.
