Ballload, power, rubble and millliners lifeline optimization
Target processing capacity increased from 15,000 t/d to 20,000 t/d; stable production of about 18,000 – 19,000 t/d, and processing capacity increased by about 20 % – 27 %.
When the ore gets hard, the ball runs, the ball hits, mill liners is reworked with the conditions of operation.
The public summary confirmed that an optimisation strategy was developed for different ores fields, with full values based on conference papers.
Ball run-down level to enter the whole Mine-to-Mill swallow-off model
The public search summary shows that the project predicts that SAG grinder throughput can increase by about 2 per cent and track the ball runoff rate.
60 mm HC media stable and reduced total cost
The rate of wear and tear is about 38.7 g/kwh, compared to 38.9 g/kwh, which is about 0.7 per cent.
Reduced grid jam and unplanned shutdown
In the large, roughput production, the stop-off risks are magnified by the ball breakage and the out-of-roll ball.
Reduction of risk of supply exposure from secure stocks
Long delivery periods for overseas projects and uncertainty about replenishments affect continuous production.
ball breakage enter downstream equipment, magnify the stoppage and production losses
The feed volume is about 1,300 t/h; power has dropped from 7,600 kW to 7,000 kW by about 8%; and the power index has decreased by about 10%.
The medium changes the grinding chemistry, which affects the recovery rate of copper gold
The recovery rate of copper increased by about 2 percentage points; the paper estimated the value of the new metals at approximately $18.7 million/year.
High chromium media allow copper recovery rates to improve in step with copper concentrate.
The recovery rate for copper increased by approximately 1.0 percentage points; the recovery rate for gold increased by about 1.3 percentage points; and the final grade for copper concentrate increased by at least 0.7 percentage points.
High consumption of media comes at the same time as low SAG throughput.
The public summary confirmed that problems existed, but that the current accessible summary did not disclose the full improvement figures.
