gsv will also be working on trade-off studies, which will look at details such as the optimal size of the mines trucks and the shovels and the size of the high-pressure grinding roll.this is a cost-effective process, provided the required particle size is reached and the leach solution can access the gold within the product. otherwise, you risk wasting valuable materials. ivrindi gold had commissioned laboratory research that confirmed that a high pressure grinding roll would benefit their process.

grinding is the result of the pressure brought on a bed of material in the gap between the rolls. It is not dependent on the the high pressure applied to the ore in hpgr crushing. this results in an enhancement of gold recoveries in e.g. heap leaching, even from the coarser grain size fractions.In fact, the advantages of utilising high pressure grinding rolls in gold are steadily increasing, as gold miners are forced to turn to deeper and deeper ore bodies with higher competency. In my early experiences working with gold mines across australia, the average bond work index encountered was probably or kwht but were now
