Pustynnoye Gold Mine processed approximately 2.0 Mt of ore in 2018 and aims to increase ore production to 2.5 Mt/a. Therefore, Pustynnoye wished to explore opportunities to increase the mill throughput by optimizing fragmentation from blasting through crushing and grinding.
Factors influencing the rate of gold cyanide leaching and ...
Improving the kinetics of adsorption means more gold will load on the carbon in a given time period, and this in turn translates to lower capital and operating costs, either by virtue of a decrease in the size or number of adsorption stages, or by an increase in the loading of gold on the carbon and a consequent decrease in the amount of carbon transferred to elution and regeneration.
FREDA REBECCA SAGMILLING CIRCUIT OPTIMIZATION
2001). Increase in throughput has been realized by simply optimizing the feed size distribution to the SAG mill. This work will look at the effect of removing fine material in the cyclone underflow through fine screening to reduce the re-circulating load. Possible installation of a ball
MINING OPTIMIZATION
Another example of Mine-to-Mill optimization is the increase of the SAG mill throughput in Porgera mine, Papua New Guinea, where by using this concept studies showed that was possible, by optimizing the blasting design, reaches up to 25% of increase in processing capacity (Grundstrom, Kanchibotla, Jankovich, & Thornton, 2001).

Feb 01, 2018 · Sometimes the changes suggested by a YET model can be relatively simple. At one gold mine, the use of an advanced-analytics approach based on sensor data revealed some unsuspected fluctuations in oxygen levels during the chemical-leaching process. Fixing the oxygen supply increased yield by 3.7 percent, worth up to $20 million annually.
