Problems with cleaning the filter plates of ceramic filters
Thread Content
Our factory is engaged in gold smelting. Ceramic filters are used to recover the gold-containing liquid from the tailings; 80% of the tailings have a fineness of less than 200 mesh, and their composition consists of iron oxide and quartz. The cleaning methods employed include ultrasonic treatment, 45% nitric acid, and water washing. However, the cleaning effect using 325-mesh filter plates is not good. I would appreciate any better suggestions from everyone out there! ! ! ! ! ! ! ! !
Generally, ultrasonic waves combined with acid cleaning can clean the surface thoroughly as long as there is sufficient power and the process is carried out for a sufficient length of time; if that doesn’t work, try using steam to blow through the filter plates first
If there’s no better way, use hydrofluoric acid! !
