levels (sulphate/zirconium = ) by prolonged washing of the zirconium bhydroxide precipitates before dissolution in nitric acid. However, this is a time consuming process and adversely effects the process efficiency. The use of concentrated sulphuric acid for silica removal also results in increased corrosion problems an well as more hazardous working conditions. Efforts have therefore been ...
Quality control analysis of raw silica and zirconium beads has identified dust, hair, and insects as contaminants. Beads need to be cleaned prior to use, one such accepted process is to acid wash. By washing in diluted acid it helps to reduce and eliminate fine particles and contaminants. Acid washing also removes potentially deleterious heavy metals adsorbed to the surface of the bead. The ...
· Energy savings from such a change could run to 50,000 per year or more at a typical plant.
