Prediction of Concentrate Grade in Industrial Gravity Separation Plant
The methods are applied in the Outokumpu Tornio Works Kemi Mine plant data. The chromite concentrate grade can be predicted relatively accurately based on the slurry properties measured in the grinding circuit. Accordingly, the predicted chromite grade decreases about 0.2 %-units when the slurry D50 passing size is increased by 10 %.
