Copper slag was characterized and processed. The pyrometallurgical processing prospects to generate utilizable materials were arrived at through rigorous thermodynamic analysis. Carbothermal reduction at elevated temperature (near 1440#176;C) helped recover a majority of the metal values (, Fe, Cu and Mo) into the ironrich alloy product which can be a feed material for steel making.
Recovery of cobalt, nickel, and copper from slags, using Mintek has been working on the recovery of cobalt, and the associated valuable metals, from slags, since 1988, using DCarc furnace technology to effect selective carbothermic reduction of the oxides of cobalt, nickel, copper, (and zinc, where present), while retaining the maximum possible quantity of iron as oxide in the slag.
Copper sulphide and copper metal (with its inherent cobalt content), because of their higher densities and immiscibility with the slag, settle from the molten slag into the metal bath. Improving recoveries via this mechanism would involve decreasing the viscosity of the slag (by increased temperature or flux additions), and / or increasing the settling time to allow smaller droplets to fall.

White Pine reverberatory furnace slags contained economically recoverable amounts of copper for a variety of reasons. Among them: White Pine concentrates yield extremely high matte grades (65+% Cu) and viscous slags. The viscous slags hinder matte settling causing matte prill entrapment in the slag. White Pines total refined copper output is accomplished through fire refining
#0183;#32;Anode slag consisting of nickel and copper at ICC, Ghatsila is used to recover copper and the residue is stored in the plant premises for possible nickel recovery (Parvathisem, 1997, Sharma, 1998a, Sharma, 1998b, Biswas et al., 1998, Amer, 2002). The converter slag is usually recycled back to the smelting furnace.
Export Import Data Solutions provides a authentic and updated trade report of Copper slag Import Data with import shipment data of Copper slag importers in slag Import Data of India is collected from Indian ports, customs, and other trusted authorities in India. Indian Copper slag Import data report helps to analyse Import price, quantity, market trends, and so on.
Copper extraction refers to the methods used to obtain copper from its conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

high quality copper slag The raw material for STAR GRITs copper slag is obtained from globally renowned sources especially from Tuticorin, Tamil Nadu. It is one of the largest copper production hubs of India with, stateoftheart smelter technology to produce high quality raw material.
Table 9: Performance of slag cements prepared by using 35% copper slag at different fineness. Observation and Analysis: Chemical analysis of granulated blast furnace and copper slag are given in Table 1. The results indicate that granulated blast furnace slag conforms to all the requirements of Indian Standard Specification IS: for the manufacture of PSC unlike copper slag.
The recovery of copper values from an Indian smelter slag that contains % Cu, % Fe and % SiO(2) was the focus of the present study. A complete investigation of the
Since the copper smelting slag contains high content of Fe, Cu and valuable metals, interest in recycling it is increasing. The high Fe content in the copper smelting slag can be used as a highvalue element that can replace the foundry pig iron. Therefore, this study was intended to recover FeCu alloy from the copper smelting slag
The optimum digestion temperature is 250oC, at which a high recovery of copper from copper slag is achieved. Figure 7. Copper in the residue at various digestion temperatures.
