مصنع لتجهيز البوكسيت/Pyrometallurgical Processing Of Copper
Scheme of pyrometallurgical processing of copper slag into the ladle After the slag is poured from the converter into the ladle, the following chemical reacti ons take place (at 1100 1200 o C):
Process for recovering copper from molten convertertype slags or other highly oxidized copper smelter slags containing 730 percent by weight of magnetite (Fe3O4). The magnetite in the slag is reduced with carbonaceous materials or other solid reductants. While the slag is mixed with a water cooled, metalbladed mechanical stirrer, the reductant is reacted with the slag.
Charge Calculations in Pyrometallurgical Processes . Smelting ... The grade of the matte is defined as the copper grade of matte A matte of 40 percent means, it has 40% copper, ... The reason for this combination is the economical processing of large amount of sulphur
The alloy produced by the pyrometallurgical process contains mainly the valuable metals copper, cobalt and nickel. Options for further processing for alloys are POX, ammonia leaching and anodically dissolving in acidic electrolytes [7]. For the investigation of this work, a POX process was chosen as it has been proven successful for similar ...
pyrometallurgical process for copper minerals. pyrometallurgical process for copper minerals. A continuously growing demand for valuable nonferrous metals and therefore an increase in their prices at the metal exchanges makes it necessary and profitable to investigate alternative metal resources.
Heat Balance in Pyrometallurgical Processes . Procedure in Calculating a Heat Balance 1. Work out the complete stoichiometry of the reactions and materials balance 2. Denote the temperatures at which all materials enter and leave the system 3.
routes of the copper production process—the pyrometallurgical route, the hydrometallurgical route and secondary copperhode production. Background data were representative of the years 2010 – 2013. The functional unit of the study was 1,000 kg of copper .
The pyrometallurgical processing of copper varies worldwide with respect to the charge materials, process, operating parameters, and the physical shape, size, and orientation of the vessel.
waste copper slag. This process is simpler than conventional pyrometallurgical process as the addition of any external collectors are not Hydrometallurgy Metal separation and recovery using hydrometallurgical processes have lower capital cost and environmental impact than pyrometallurgy, and offer greater scope for selective metal

As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any sizereduction requirements including, Flow sheet for pyrometallurgical extraction of copper from cu2s concentrate, quarry, aggregate, and different kinds of minerals.
However, pyrometallurgical processes produce large quantities of slag, and this constitutes one of the main byproducts of the metal extraction industry [2]. The average composition of primary copper slag corresponds to 3040 % iron, 35– 40% silica, less than 10 % of alumina and calcium oxide and copper
granulated copper slag is made up of regularly shaped angular particles, mostly between and mm3. Slags produced during pyrometallurgical processes have been traditionally considered as a waste3. In the case of copper extraction processes, it has been estimated that for every ton/year of copper produced, ton/year of slag is
