Mineral resource classification plays an important role in the downstream activities of a mining project. Spatial modeling of the grade variability in a deposit directly impacts the evaluation of recovery functions, such as the tonnage, metal quantity and mean grade above cutoffs. The use of geostatistical simulations for this purpose is becoming popular among …

By Keith Vining. Using CSIRO's Mineral4/Recognition4 to predict ore behaviour. Ore classification by mineral and textural type is a critical method for predicting the behaviour of iron ore fines during beneficiation and in sintering and pelletising agglomeration processes.. In current industry practice, chemistry (or ore grade) is the primary measure of ore quality.

Double deck roller screens are often used in iron ore pelletizing circuits to control the size of green pellets entering the induration furnace. Besides removing fines that would increase the pressure drop in the furnace, they can also improve the permeability of the bed by inducing stratification. In spite of the widespread use of roller screens in industry, very little …

identification and classification of iron ore is the most important step in quality control. In general, the element content of iron ore should be identified in both qualita-tive and quantitative methods 12. However, it is time-con-suming and requires complicated sample preparation. In order to rapidly classify the iron ore grades, the LIBS

01 Iron ore tailings classification. Iron ore tailings can be divided into magnetite tailings and hematite tailings according to the mineral properties of the raw ore. Due to the large displacement of magnetite, its production output is three times that of hematite, so the displacement of magnetite tailings is greater than that of hematite tailings. .
