Recovery of metal values from copper slags by flotation

The recovery of copper and cobalt from ancient copper slags from the Küre region of Turkey was investigated. A fayalitic-type of ancient copper slag containing 1.24% Cu, 0.53% Co and 53.16% Fe were subjected to an experimental study. Two different routes were followed to recover the metal values. The first route was roasting the slag with pyrite followed by leaching.

Recovery of Copper from Reverberatory Copper Slag and

Recovery of Copper from Reverberatory Copper Slag Slags are waste minerals produced during furnace smelting of minerals. The contained because copper slag has a bond work index of 22 kWh/t and is thus a very hard slag. The process also has reduced flotation recoveries and requires high flotation reagent consumption.
