S. Makni et D. Hodouin, RECURSIVE BILMAT ALGORITHM - AN ONLINE EXTENSION OF DATA RECONCILIATION TECHNIQUES FOR STEADY-STATE BILINEAR MATERIAL BALANCE, Minerals engineering, 7(9), 1994, pp. 1179-1191
The paper proposes a method to correct measured mineral processing var
iables and simultaneously estimate unmeasured ones, using an on-line m
aterial balance program. The technique is an extension of the steady-s
tate material balance algorithm BILMAT for redundant measurements of s
tream ore flowrates and compositions on any complex flowsheet. The pro
posed method reconciles data with material conservation equations on a
real-time basis, using information in a moving window. The computatio
n algorithm is recursive and easy to implement. It is illustrated on a
simulated flotation circuit.
