The feasibility and regularity of dearsenication from cobalt-arsenic under vacuum have been investigated on the self-made vacuum furnace. The influences of temperature, time, residual pressure, and pellet size on the envaporation ratio of arsenic have been tested with the fixed furnace configuration. The experimental results show that the process of dearsenication from cobalt-arsenic concentrate by vacuum distillation is effective. Under proper conditions, the envaporation ratio of arsenic comes up to 89% approx. 95%. When the condensate experiences redistillation under vacuum, refined arsenic can be obtained which contains 99.7% arsenic.
