Reagents in iron ores flotation - ScienceDirect

2005-2-1  The role of reagents utilised in iron ores flotation is reviewed. Desliming and flotation stages should be performed at pH levels as low as possible to reduce the expenses with caustic soda. Ether amines are by far the mostly utilised class of collector. The degree of neutralisation of the ether amine is an important process parameter.

Reagent dosage intelligent optimal setting for iron ore ...

2019-6-5  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.
