Sep 11, 2014· 1. Roasting. Copper anode slimes are roasted at 600–800°C with sulfuric acid or oxygen, which depends on the composition of slimes. During the process, selenium is evaporated in the form of SeO 2 gas. Copper is present in the form of soluble copper sulfate, which can be removed with dilute acid or water leaching.

The mud or slime is coUected from the bottom of the electrolytic ceUs and pumped to the sUver refinery, where it is processed for recovery of copper, precious metals, selenium, and, in many cases, teUurium. The anode slime contains 2—20% selenium as copper and sUver selenides, whereas gold exists as the metal and in combination with teUurium.
