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 …
Hence, a mill is a piece of equipment used to grind ores. Its major purpose is to perform the grinding and blending of rocks and ores to release any free-gold that is contained within them. At major mines, the mill was the critical equipment that was required to process the ores that were extracted from deep underground.
Scrap waste grinding for metal recovery. 20 November 2019.
