Recovery of metal values from copper slags by flotation ...

Feb 01, 2007· 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.

1.1 Lab Cu expt.

Since no copper is added or removed between the initial and final reaction steps, copper can be quantitatively recovered. In other words to recover the same amount of copper metal that you started with, this will require careful work. The success of the copper metal recovery will be shown by calculating the percent yield.
