·
In any industrial production process, variation of raw materials takes place.
·
Significant variations affect the production process negatively
·
Any mineral production process is optimized to neutralize variations and
doesn’t work in optimal regime
Therefore, in mineral production, a typical technological task consists in stabilizing properties of the raw materials
·
Periodic
pin-pointed measurements miss the variation of batch parameters.
·
Average measurements over a long
time period do not provide enough information.
·
Lab analysis for the 24/7 real-time process control is impossible.
·
Laboratory data does not allow online control of the production process
When a process has significant variations, real time data can be more important than very high accuracy at individual points.
