An efficient separation for metal-ions from wastewater by ion PubMed
Hazardous metal pollution became a severe environmental issue in China. An efficient precipitation-flotation process was developed to achieve fast removal for metal-ions from wastewater. Structure and strength of precipitate particles/flocs significantly influence the flotation removal of metal-ions The XFG II5 hanging cell flotation machine (Jilin Exploration Machinery Factory, Changchun City, Jilin Province, China) was used in this experiment. In the pure mineral flotation experiments, the volume of the flotation cell was 40 ml, and the stirring speed of the flotation machine was set at 1989 rmin −1 .Flotation separation of spodumene and albite with activation

The Magic Effect of Lime in Mineral Processing JXSC Machine
Contact Now +86-13879771862. Published time：20 February 2021. Lime is widely used in mineral processing areas, like beneficiation processing, flotation processing, and leach processing. Also, lime can be used to raises the pH value, thus precipitating metals diluted in the water into tailing areas. And limestone is often used in Oil removal from produced water was studied in an induced gas flotation machine to (1) determine influential parameters in oil removal efficiency, (2) develop efficiency models, and (3) predict machine settings for optimal performance. Chemical concentration and flow rate were found to be the performance. Chemical concentration Performance Evaluation of Induced Gas Flotation Machine

Potash flotation practice for carnallite resources in the Qinghai
The carnallite is harvested by dredging. The evaporation rate is relatively slow because the temperature in this area is low (average temperature in spring is −6–9 °C, in summer 9–22 °C, in autumn 5–19 °C, in winter −13 to −1 °C). The chemical analysis for the carnallite mixed crystal sample is presented in Table 3.Precipitation flotation and adsorption flotation will produce large amounts of sludge, As shown in Fig. 3, more than 95% can be removed when the gas is self-attracted by the impeller of the flotation machine, and this removal rate does not change substantially with increasing ventilation.ScienceDirect Ion flotation of heavy metal ions by using
