The methods of gravity settling,demulsification resin treatment,and activated carbon adsorption were used to treat the oil-containing waste water from rare earth hydrometallurgy process.
In this paper,using oxalic acid precipitation method to remove the small amount of calcium in magnesium sulfate wastewater of rare earth transformation was studied.
In this work,we have investigated the magnetic properties and MCE in La0.7Ca0.3MnO3 compounds which were prepared by a conventional solid-state reaction method.
The study is carried out to explore the effect on diesel fuel combustion by the adding of the composite particles of cerium oxide and tourmaline which is mixed by mechanical stirring.
Disposal principle,process and approaches of associated radioactive waste were described in this paper.Basis of methods selection and impact pathway for different disposal approaches were also discuss
The objective of this study was to investigate the removal process optimization and perform an efficiency assessment,while varying different factors,such as saponin concentration,pH of saponin solutio
In this paper,a rare earth separation enterprise was taken as an example and the monitoring data of the radioactive pollution source of the enterprise were used as the source term in the prediction.
