"Inhibition Of Water Formed Scale In Acid Conditions"
Abstract: The current invention relates to the inhibition of scale deposits in an acidic slurry or solution. The current invention uses an aqueous synthetic mixture comprising a phosphate, phosphonate, anionic polymer, or combinations thereof in the slurry and/or solution to inhibit scale during the processing of ore. The production of scale in an acidic environment is difficult because of the acidic solution neutralizing most known inhibitors. The claimed invention has a significant decrease in the scale production allowing for reduced down time of systems for de-scaling procedures
