Mineral processing plant data reconciliation including mineral mass …
The operation of mineral processing units or plants is related to the mineral composition of the ore. However, unit performances are usually characterized in terms of metal content or recovery as this data is easier to be obtained rather than the mineral content. This paper presents a data reconciliation method that combines material balancing calculations and mineral stoichiometric ...
