Production of copper concentrate by flotation of smelter slag has started in 2001. Flotation concentrate goes to the Copepr Smelter once more for production of cop-per cathodes and the rough flotation tailings go to the flotation tailing dump. Copper recoveries in the flotation process of smelter slag reaches the value of about 45- 50.
This slurry is processed though the several flotation stages. The process recovers all valuable components of the ore, such as zinc, copper and precious metals. In the first stage of the flotation process bulk flotation, the slurry with reagents is pumped into flotation tanks and injected with air to
In this study the effect of mixtures of copper slag and flotation tailings from copper mine Bor, Serbia on the flotation results of copper recovery and flotation kinetics parameters in a batch flotation cell has been investigated. By simultaneous adding old flotation tailings in the ball mill at the rate of 9, it is possible to increase copper recovery for about 20.
The cumulative copper recoveries increased markedly to over 90, which represents a significant improvement in comparison to the recoveries obtained from the mill-float process. Sodium alkyl dithiophosphate, mercaptobenzothiazole FC7245 was found to be the secondary flotation reagent that gave the best copper recoveries.

One of the major problems in copper-producing countries is the treatment of the large amount of copper slag or copper flotation waste generated from copper slag which contains significant amounts of heavy metals such as Cu, Zn, Pb and Co. Dumping or disposal of such large quantities of flotation waste from copper slag causes environmental and space problems.
phase, the slag. In most copper extraction processes, matte is an intermediate phase. The pyrometallurgical production of copper from sulfide ore concentrates is a rough separation of the three main elements as crude copper, iron II silicate slag, and sulfur dioxide. Slag containing 0.8 wt copper are either discarded as waste or sold as ...

The Kansanshi copper smelter KCS that started commercial operations in March 2015 has the current capacity to smelt 1.38Mtpa of copper concentrate. It features a single Isasmelt furnace, one 6-in-line electric furnace for matte settling and slag cleaning, four PeirceSmith converters PSCs, and two conventional rotary anode furnaces.
A method is disclosed for treating dore slag resulting from smelting of a dore furnace charge, by grinding such slag and then subjecting the obtained pulp to froth flotation in the presence of a suitable frother and collector to produce a precious metals concentrate which is then filtered and returned to the dore furnace with the next charge.
Apr 05, 2015 The content of copper in the flotation tailings directly depends on fragmentation rate Figure 1. Expected content of copper in the flotation tailings, in the case of cooling in pits, is 0.5-0.9, and in the case of cooling in pots, from 0.22 to 0.35 Cu. Fig. 1. The effect of fragmentation rate on the slag flotation 6
of slag per year, the copper recovery re-mained low 50 10. The reason for this is the presence of 15-20 of copper oxide in slag and concentrated sulphide copper in the size classes below 38 m 11. Therefore, in the tailings from the flotation of slag, copper lags whose concentration is
Key words Converter slag, flotation, copper, cobalt, sulphurization. 1. Introduction Copper slag is produced in large amounts in seven copper smelter plants in Chile, and it is estimated that around 4 million tons of slag are disposed every year and another
Copper slag flotation was studied on an industrial scale at a concentrator plant in the region of Atacama, Chile. This study consisted of the physical, chemical, and mineralogical characterization of the copper slag, along with preliminary flotation tests.

Jan 28, 2021 Copper slag also has a high strength-to-weight ratio, making it an effective option in concrete, or as a fill material under the roadway. When added to concrete, it makes the paved surface less porous, which minimizes problems with moisture and freezing. It also makes concrete more fire resistant, and helps to slow the spread of heat and flames.
