PRODUCING METHOD FOR CRYSTALLINE SCORODITE

摘要

PURPOSE: A method for manufacturing crystalline scorodite is provided to reduce water consumption amount or the burden of pumping equipment by reducing the cleaning water amount of scorodite. CONSTITUTION: A method for manufacturing crystalline scorodite comprises following steps. Acidic aqueous solution heats temperature and time which are effective for the synthesis of crystalline scorodite. The synthesized scorodite is separated from solution by the solid-liquid separation after reaction. The scorodite is washed by water and is separated from the washing liquid through a solid-liquid separation method.
