Interaction and Corelation of Reagents in Flotation Systerm of Rare-earth Mineral

The interaction of Na₂SiO₃, H₂₀₅ and H₁₀₂ reagents was studied with orthogonal regression methed, and a regression methematical model is yielded. It deals with the dosages of the three reagents as well as the grade (β) and the recovery rate (ε) of RE minerals in flotation system. The experiment results show that the order of the interaction of the reagents is as follows:H₂₀₅-Na₂SiO₃>H₂₀₅-H₁₀₂>Na₂SiO₃-H₁₀₂.
