calculate the input ratio of WEES and waste copper slag in the reduction smelting step.) Fig. 3 Schematic diagram of experimental apparatus used in this study. A High Temperature Process for Extracting Valuable Metals from Waste Electric and Electronic Scraps (WEES) 1559
Waste copper slag is a refractory material with high iron content, but it is difficult to recovery iron minerals from the slag because the iron mainly occurs in fayalite. A new technology of coalbased direct reductionmagnetic separation process was developed to recover iron from the slag assaying % Fe total and % Cu.
per annum waste. The state of Gujarat accounts for around 70% of total ceramic production in India and out of total production 30% goes as waste and dumped in the open spaces . The advantages of using ceramic waste dust in road construction as mineral filler are: (i) the ceramic dust available at zero economic cost, (ii) chemical and
The copper slag has been used for cement material, sand blasting, reclamation and so on. However, most of the copper slag is stacked high as waste since the production exceeds demand. This study on the application of copper slag as fine aggregate for concrete has been started with the expectation of large amounts of consumption.

the environment. Copper slag is one of the waste materials that are being used extensively in the civil engineering construction industry. Copper producing units in India leave thousands of tonnes of copper slag as waste every day. Large quantities of the accumulated slag is dumped and left on costly land, causing wastage of good cultivable land.
Application of PS Ball as Abrasive Blasting Material It is being widely used in the field of ship repair industries and oil refinery plant maintenance for shot blasting purpose, PS Ball itself has shaped in a stable and safe form, not pollutant and harder that Copper Slag or Sand. Less risky to the operators and neighbors, low levels of
on the reduction of slag from ﬂ ash furnace and the use of carbon granulates obtained from ﬁ negrained waste materials of both the coal enrichment and coking processes have been presented in the paper. The slag generated during the blister copper production is characterized by a considerable amount of this metal, at times up to 16 % mass.
50% copper slag substitution in comparison with the control mixture. The results obtained for concrete indicated that there is a slight increase in density of nearly 5% as copper slag content increases, whereas the workability increased significantly as copper slag percentage increased compared with the .

Among the specimens with cement only and with oth cement and copper slag, the stabilized specimens with both 6% cement and 20% copper slag after 90 curing days had the highest values of elastic modulus at 375 MPa, which was at times more than that of the unstabilized soil, which mad up 133 MPa.

Sep 01, 2014· Utilization Of Industrial Waste Copper Slag And Fly Ash In Concrete Jagmeet Dhanoa 00:00:00 The present investigation assesses the incorporation of industrial waste copper slag and fly ash in concrete. The combined effect of copper slag (CS) and fly ash (FA) as a partial replacement of cement on the compressive strength of concrete has been investigated.
