英文摘要: Abstract(#br)In the traditional alkali smelting process of tungsten ore,a small amount of the associated phosphorus will enter the sodium tungstate solution. In order to produce a qualified tungsten product, phosphorus must be removed in depth. Conventional methods for removing phosphorus, such as magnesium salt precipitation, ion exchange, etc., are difficult to efficiently remove high concentrations of phosphorus from sodium tungstate solution. In this paper, a method for deep phosphorus removal from crude sodium tungstate solution by hydrogen peroxide coordination‑calcium salt precipitation is proposed due to the coordination ability of hydrogen peroxide with tungstate to form peroxytungstate which is difficult to be precipitated by calcium. The paper mainly explores the theoretical...
