Physics and Chemistry of the Hydrogen Fluoride Production Process from Fluorine Containing Waste

The impact of the aluminum industry wastes on the environment is established. The resource efficient method of aluminum industry fluorine-containing wastes processing, which includes wastes oxidizing roasting to remove carbon component and the interaction of fluorine- containing particles with sulfuric acid in order to produce hydrogen fluoride, is considered. The economic and environmental effect of the proposed processing method is substantiated

The Research of (NH4)2BeF4 Solution Purification Effectiveness

AbstractThe research work topicality is based on necessity of beryllium production from fluorine containing raw materials technology optimization, beryllium losses minimization and environmental impact decrease by beryllium and materials based on beryllium production. The goal of research is identification of beryllium containing solutions produced in the result of beryllium concentrate fluorineammonium processing purification possibility (clarification of iron, aluminum, calcium and silicon) and conditions provided maximum impurity removal from solution, which do not cause beryllium hydrolysis
