Ozer Istanbul Technical University, Mining Faculty, Mineral Processing Engineering Department, Maslak, Istanbul (Received 04 March 2019; accepted 22 July 2019) Abstract The ancient flotation tailings from Lefke, Cyprus, have a potential for non-ferrous metals such as cobalt and copper from
Contact2018. 6. 15. Some researchers have investigated the possibility of copper recovery from the tailings using bioleaching and atmospheric leaching [ 6, [26], [27], [28] ]. Since the bioleaching process is very slow and sometimes produces toxic chemicals [ 28, 29 ], most studies are focused on atmospheric leaching.

Based on the results, shown in Figure 4, the optimal ratio of S:L for the copper leaching process from flotation tailings is 1:2.5. The highest degree of copper leaching of 56% was achieved in the following

ContactCopper tailing is the waste rock remaining after ore has been processed to remove the copper. It is usually pulverized to the size of fine sand. It has relatively high specific gravity and primarily consists of silica in its composition.

Low copper extractions both from the slag and the slag flotation tailings indicate that sulphuric acid is not a suitable reagent for leaching these materials, at room temperature. This conclusion is in line with the study by Banza et al. (2002) where the leaching of copper smelter slag with sulphuric acid (500 kg/Mg slag)

This kind of ore is usually processed by mill running and then smelting, and the copper recovery is about 35% during the mill running process. Sun at al.
