Abstract
The present disclosure relates to a device and method for recovering arsenic and gallium. A closed furnace body is in communication with a vacuuming pipe, and the vacuuming pipe is connected to a vacuuming mechanism. The closed furnace body includes a first furnace body, a second furnace body and a third furnace body. A first heating mechanism and a graphite crucible are arranged inside the first furnace body, the first heating mechanism being used for heating the graphite crucible. A first collection cylinder is in communication with a second collection cylinder. The device for recovering arsenic and gallium of the present disclosure is arranged with a structure for realizing directional condensation of gallium arsenide clusters and arsenic vapor, respectively, to realize high-purity recovery of arsenic and gallium.
