US3666440A Method of recovering copper from slag. copper is recovered from copper-containing slag by putting the matte and slag in a molten state together in a slag treating furnace at a volume ration of more than 15, the melts in the furnace being maintained under agitation so that the slag and matte are in intimate contact so as to efficiently transfer copper from the slag to the matte.
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 slag in the molten state needs to be cooled, and the way it is cooled determines its properties and commercial use; for example, in the recovery of copper, slow cooling of slag leads to a recovery of about 98.5% [32,33,34]. The molten slag solidifies during cooling in different ways depending on whether it is cooled under atmospheric conditions, by using measured quantities of water, by

Copper slag was characterized and processed. The pyro-metallurgical processing prospects to generate utilizable materials were arrived at through rigorous thermodynamic analysis. Carbothermal reduction at elevated temperature (near 1440°C) helped recover a majority of the metal values (e.g., Fe, Cu and Mo) into the iron-rich alloy product which can be a feed material for steel making. On the

Copper slag grit manufacturer, which is created while pyrometallurgical creation of copper from copper metals contains materials like iron, alumina, calcium oxide, silica, and so on For each huge load of metal creation about 2.2 huge loads of slag is produced. Unloading or removal of such immense measures of slag causes ecological and space issues. During the earlier twenty years, endeavors
In the present paper, recovery of valuable metals from copper smelter slag of Balkhash copper plant (Kazakhstan) was investigated. To recover Fe, Zn and Cu to water-soluble form, the mixture of 150 g of copper slag and 60 g of 85% sulfuric acid was granulated and then roasted in the temperature range of 473–643 K (200–370 °C) followed by sulfuric acid leaching. Once the roasting
