Synergetic Effect of the Mixed Anionic/Non-Ionic Collectors in Low Temperature Flotation of Scheelite

The synergetic effect of four octaphenyl polyoxyethyienes (TX) on low temperature flotation of scheelite at 9–11 ◦C was investigated through flotation experiments, and the adsorption mechanism was studied by way of surface tension, zeta potential, and adsorption measurement. The results show that the presence of the four octaphenyl polyoxyethyienes can improve scheelite flotation in a low conce...

approaching zero-discharge with cleaner production: case study of a sulfide mine flotation plant in china

in order to decrease the discharge from sulfide mine flotation plants, treatment and reuse approaches based on our previous wastewater monitoring experiments were explored in these plants. the flotation wastewater was collected from the case plant and was treated with coagulation sedimentation and activated carbon adsorption. then, the effluent was examined for reuse in the flotation process. f...

Flotation Separation of Scheelite from Fluorite Using Sodium Polyacrylate as Inhibitor

The depressing properties of sodium polyacrylate (PA-Na) for scheelite and fluorite were studied by micro-flotation tests, infrared spectroscopy (IR), zeta potentials, X-ray photoelectron spectroscopy (XPS), and density functional theory (DFT). The flotation results reveal that the selective depression effect of PA-Na is better than that of sodium silicate, and PA-Na can depress fluorite more e...

Pediatric nutrition in practice: 2nd revised edition

In the first section, the authors have attempted to describe most of the aspects of childhood nutrition in a concise manner. The topics have been chosen carefully and the authors have done justice with the subject. Apart from describing the process of nutritional assessment, nutritional needs of various age groups and the contribution of essential constituents like protein, carbohydrates and fa...
