ABSTRACT OF THE DISCLOSURE: A process for controlled slow cooling of non-ferrous smelting slags, such as copper slags, for the recovery of the non-ferrous metals contained therein by subsequent crushing, mil- ling and flotation operations is disclosed. The process compri- ses the steps of pouring the molten slag into a ladle, allowing the slag to slowly cool and solidify in the ladle at least to the point where a shell is formed which is strong enough to withstand dumping from the ladle, dumping the slag from the la- dle in a single piece, allowing the dumped slag to cool until its center is substantially solidified, and breaking the dumped slag in small pieces for further cooling, crushing, milling and flo- tation operations. Alternatively, the top of the slag in the ladle may be water cooled while the slag is allowed to slowly cool in the ladle until its center is substantially solidified. The slag is then dumped and subsequently broken in small pieces.
