| Gross loss calculation example -Medium pressure plant 600 tonnes acid per day production; plant runs 330 days per year; age 15 years; gross loss 0.15g pgm per tonne acid; catchment installed operating at 70% efficiency. Therefore net loss - 0.045g pgm per tonne acid produced. Total loss of pgm (600 x 330 x 15 x 0.045) - 133,650g Pt + trace Rh. Loss of Palladium from catchment would be similar to Pt loss, i.e. 133,650g. This would give a total loss of pgm of 267,300g. |
