Optimization on selenium and arsenic conversion from copper anode slime
A process was proposed to convert and separate selenium and arsenic in copper anode slime (CAS) by low-temperature alkali fusion process. Central composite design was employed to optimize the effective parameters, in which NaOH/CAS mass ratio, fusion temperature and fusion time were selected as variables, and the conversion ratio …
