|ABSTRACT||We have developed the process for recovery and recycling of valuable metal
and nitric-hydrofluoric acids from waste pickling solution for stainless
steel. There are 3 objectives for this process.
Experiments were conducted sequentially process(1)→(2)→(3) to develop these three process by bench plant (the treatment of waste pickling solution was 454 L/month). The following results were obtained.
From these results, we have developed a successful process for recovery and recycling of valuable metal and nitric-hydrofluoric acids from waste pickling solutions for stainless steel.
