摘要:
A process for recovering metal values from furnace skim comprising a controlled wet comminution of the skim at a reduced work input level in a ball mill having a ball charge of from 5 to 20 percent of the internal mill volume. The comminuted product is separated into a coarse and fine fraction, the coarse fraction being substantially metal and the fine fraction being substantially non-metals such as oxides, nitrides, and the like.
