Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 99.99 pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different …
Slag produced by flash furnace operations contains significantly higher amounts of copper than reverberatory or electric furnaces. Flash furnace slag is treated in a slag cleaning furnace with coke or iron sulfide. Because copper has a higher affinity for sulfur than oxygen, the copper in the slag (as copper oxide) is converted to copper sulfide.

A new copper processing facility is being constructed where a pressure of 0.2 atmospheres SO_2 is desired while oxidizing copper matte. Superimpose this pressure in Equation 3 onto a predominance area diagram of the Cu-S-0 system: Use log (pS_2) on the y-axis and log (pO_2) on the x-axis. The thermodynamic reactions involved are shown in Table 1.
Copper slag, or fayalite slag, is a by-product obtained during the matte smelting, converting and refining of copper (Fig. 7.11). 54,59 It has been estimated that for every tonne of copper produced, about 2.2 tonnes of slag is generated, 60 as a consequence of the relatively low grades of copper …

Copper slag is used in mortar as a replacement copper slag reduced the strength of concrete. Author gives of sand in different proportion from 0% to and mortar is recommended percentage ...
May 03, 2014· The unit weight of copper slag is somewhat higher than that of conventional aggregate. The absorption of the material is typically very low (0.13 %). Granulated copper slag is more porous and therefore has lower specific gravity and higher absorption than air-cooled copper slag. The granulated copper slag is made up of regularly shaped, angular ...
With the dynamic smelting processes copper losses in the slag can be divided as: such are Flesh; INCO …, copper content in electrochemical losses (chemical and the silicate slag could reach up to 2%, which physical) which present 65-80% of overall demands further processing of the slag.

3.3. Copper Slag Copper slag is a by-product material produced from the process of manufacturing copper. The end product is a solid, hard material that goes to the crusher for further processing. Copper slag used in this work was bought from Sterlite industries (India) ltd, Tuticorin, Tamil Nadu, India.
The slag may be fed back into the flash furnace to act as a flux, and the sulfur dioxide is processed through the acid plant. After the slag is removed, a final injection of oxygen removes all but a trace of sulfur. The resulting molten material is called the blister and contains about 99% copper by weight.
these slag products. The chemical characteristics of the copper slags are dependent upon the mineral content of the ore feed, the processing parameters, the completeness of the reduction process, and exposure to contaminants during and after air or water quenching.

demands further processing of the slag. Processing of such, copper rich slag, is facilitated using flotation or electro-precipitation of remaining sulfides resulting with about 0.5% Cu in the remaining waste slag [2, 3]. Those copper losses in the waste slag are strongly influencing the economy of the copper extraction process. Also, it is a
Copper slag is a by-product formed during the copper smelting process. The molten copper forms at the bottom of the furnace while molten slag is formed on top.
