The.le.ching te.0}e.ature. hydroge. pe.oxide.conce.tration, sulfuric acid conce.tration, le.ching tim., particle.size. liquid-to-solid ratio and agitation spe.d all have.significant e.fe.ts on the.proce.s.

Unde. the.e.e.pe.im.ntal conditions, the.e.traction e.ficie.cy of m.lybde.um.was about 98.4%, and the.uranium.e.traction e.ficie.cy was about 98.7%.

The.te.0}e.ature. conce.trations of H202 and H2SO4 and the.m.sh size.are.the.m.in factors that influe.ce.the.le.ching rate. The.re.ction orde. in H2SO4 was 1.0012 and in H202 it was 1.2544.
