Dependence Of Mine Revenue On The Grade Of Copper Concentrate

DEPENDENCE OF MINE REVENUE ON THE GRADE OF COPPER

Dependence of mine revenue on the grade of copper concentrate 549 Parameter A in formula (3) can be determined experimentally by using a series of observations { } and {β} or by using the hypothesis that it will progress as in Fig. 3a. Then, by knowing the current value and β parameter A can be adjusted iteratively for compliance of the calculated result with the measured one.
