The invention mainly belongs to the technical field of
rhodium recovery and particularly relates to a method for recovering
rhodium from an inactive
rhodium-containing homogeneous catalyst. The methodcomprises the following steps that
organic matter in the rhodium-containing homogeneous catalyst is recovered in a
distillation mode at first, and rhodium concentrate is obtained; then the rhodium concentrate is mixed with transitional
metal M, a reduction agent and a
slag former, rhodium is recovered in a
smelting manner and forms a low-melting-point Rh-M
alloy together with the transitional
metal M, then the Rh-M
alloy is subjected to
electrolysis or acidolysis to obtain rhodium
powder, finally the rhodium
powder is smelted through an electric-arc furnace, and accordingly a rhodium
ingot isobtained. The method is suitable for various inactive rhodium-containing homogeneous catalysts, the situation that the
organic matter is directly incinerated to cause
air pollution is avoided, meanwhile, the high-melting-point rhodium can be converted into the low-melting-point high-reactivity Rh-M
alloy, and subsequent rhodium
smelting and purification are facilitated. The method has the advantages of being high in rhodium
recovery rate and production efficiency, free of
pollution and suitable for industrial application.
