The reverberatory slag is produced from the reverberatory smelting furnace and usually produces the slag that is more dilute in copper of about 0.6% and is discarded without slag recovery treatment (Davenport et al., 2002). The smelter slag is produced from the smelting furnaces and contains copper with average of 1.2%.

The growth of electric arc furnace (EAF) steelmaking in North America has occurred mainly in the past 40 years due to low electricity prices, an abundance of steel scrap (especially near large population centers), and the development of mini and macro steel mills based on metal recycling. Scrap availability and price has made steel …

Copper slag, a waste solid produced in the copper smelting process, is a high-quality secondary resource with huge output. The recycling and utilization of copper slag is of great interest because it avoids the loss of valuable metals and the threat of harmful metals, and saves a lot of natural resources and energy. This paper firstly …

Blast furnace (BF) slag, which is the main byproduct in the ironmaking process, contains large amounts of sensible heat. To recover the heat, a new waste heat-recovery system—granulating molten BF slag by rotary multinozzles cup atomizer and pyrolyzing printed circuited board with obtained hot BF slag particle—was proposed in …

Slag of steel plant of furnace containing 10 to 20% pure metal but discharged in the form of slag or waste product due to improper operation But the slag of steel plant is no more the waste product !because our crusher separator plant is simple & efficient source of purifying metal from slag or furnace waste. Features:

The steel industry, in accordance with the momentum of greener industry, has welcomed the changes and is actively pursuing that objective. One such activity is the commitment to energy recovery from by-products such as slag since the average energy content of ferrous slags is around 1 to 2 GJ/tslag. The recovered energy could, then, be …

The variety of slag compositions of Table 1, is inherent to both the concentrate composition and the extraction method applied.Each slag composition requires an appropriate treatment method for further metal recovery or for utilization as construction material [27,28].Thermal reduction of copper smelter slags with solid carbon is commonly …

A considerable amount of heat energy is contained in the molten slag tapped from blast furnace.At present,the BF slag is treated by impinging much water for granulation and the energy is wasted without recovery.Thus,dry granulation technology has attracted more and more attention.The basic problems and technical difficulties of dry granulation were …
