To achieve the utilization of fine ilmenite (especially ?0.075 mm) produced in titanium-magnetite processing plant Panzhihua, a radial turbulent outer-cylinder magnetic separator (RTOCMS), was developed this study. After optimizing conditions rotation speed and water flow, an RTOCMS concentrate with TiO2 grade 22.84% recovery 66.93% obtained through one-stage roughing pre-concentration flowshee...

Magnetite nanoparticles combined with polymers produce white-light emission under multiphoton laser irradiation. Understanding the photonic reaction in magnetite-polymer composites is critical for application of magnetite NPs as photothermal agents. Laser irradiated magnetite nanoparticle-poly(methyl methacrylate) (PMMA) composites exhibit fluorescence due to the carbon double-bond formation re...

A new approach to batch grinding kinetics was established based on the conventional population balance model, with magnetite as experimental object. The distribution function commonly used in model is a sum of two power functions, i.e., Bi1=φ(xi−1x1+1−φ(xi−1x1)β. Based finding that cumulative mass fraction coarser than size class discharge consistent first-order kinetic, gi only single function...

According to the classification of the nickel laterite, this paper describes mineralogy test is to reveal where valuable elements are located in the ore, in which mineralogical form. The purpose of the sieving test was to study if some specific particle size contains most of the valuable metals. Based on its chemical composition nickel laterite is classified as a limonite type and the nickel an...

Beneficiation of a low-grade iron ore was investigated by combination of the low-intensity magnetic separation and reverse flotation methods. The main constituents of the representative sample were 36.86% Fe, 8.1% FeO, 14.2% CaO, 13.6% SiO2, and 0.12% S based on the X-ray fluorescence, titration, and Leco analysis methods. The mineralogical studies by the X-ray diffraction, scanning electron mi...
