01/01/2020· Namibia Custom Smelters (NCS) process a range of copper concentrates in their three furnaces, namely; top submerged lance, copper converter and reverberatory furnaces, in order to produce mattes and fayalitic slags. The copper content of the slags range between 0.8 to 5 wt. % and this is considered too high for disposal to the environment.
As seen in Fig. 1, the best flotation yield was at pH 11.0. For flotation, 100 g of the ore sample was fed and 28.56 g of converter slag was floated.

In recent years, there has been a move toward recovering copper from converter-type slags by milling and flotation. The term "converter-type slag" is intended to represent a slag that contains a high amount of magnetite (Fe 3 O 4) and a low amount of silica. Such slags typically contain 7-30 percent magnetite and 20-30 percent silica (SiO 2).
Keywords: copper slag, copper slag flotation tailings, leaching, sulphuric acid, ferric sulphate, hydrogen peroxide Introduction The pyrometallurgical processing of copper concentrates generates large amounts of copper-containing slag. Management options for this slag include recycling, recovery of metal values, production of value added products and disposal (Gorai and Jana, 2003). However
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.
