    Reagent dosage intelligent optimal setting for iron ore

    Jun 05, 2019 Abstract: Reagent dosage setting is closely related to the product quality and economic benefit of an iron ore flotation process. The strong nonlinearities, uncertainties and coupling of the flotation process make it difficult to set proper reagent dosage. In this paper, a reagent dosage intelligent optimal setting method based on case-based reasoning (CBR) is put forward

When using a conventional flotation reagent scheme and flowsheet, only a few of these ores respond (i.e. lime + NaCN + collector), giving extremely poor metallurgical results. The majority of these ores require a specific treatment process to achieve satisfactory metallurgical results
