a new smelting facility or modernizing an existing operation. Recent developments in copper smelting are reviewed with particular reference to the newer smelting processes. Cri teria for process selection, the impact of oxygen enrichment, energy consumption, environmental controls, and investment costs are discussed. INTRODUCTION
Economies of scale have been real- ized in all phases of copper production. Both ma- chine and human productivity have increased dramatically. This chapter briefly describes the technology …
Process flow diagram of recovering molybdenum from copper smelting dust. Firstly, the copper-smelting dust was acid-leached. >94 % of molybdenum entered the solution under the conditions of a liquid-solid ratio of 2.5:1, a leaching time of 2 h, 100 g/L sulfuric acid, and a leaching temperature of 80 °C.
This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores, in four basic steps: 1) froth flotation, 2) thickening, 3) smelting, and …

Figure 6-2.—Early Smelting Technology Charcoal ore flux m The Egyptian copper smelting furnace was filled with a mixture of copper ore, charcoal and iron ore to act as a flux. It was blown for several hours by foot or hand bellows. By the end of the smelt the copper had separated from the slag, which was tapped off.
Initially, the baiyin copper smelting process was air smelting. In 1988, oxygen-enriched air smelting was adopted, and the oxygen concentration was 45–55%. The technical process is as follows: the charge materials (containing 7–8% of water, with a small amount of block materials of a size less than 30 mm allowed) are added into the molten bath in the smelting zone through …

effective copper and lead smelting process available in the world today. The history of the process has been documented in a number of earlier published papers [1-10]. The ISASMELT process was developed from pilot plant to commercial scale during the 1980s and 1990s at MIM's smelting operations in Mount Isa, Australia.
Fig. 5 illustrates the flow diagram of the process of metallurgical recycling of CS. The quality of copper in an iron-rich alloy depends on the proportions of Cu and Fe in the initial slag (prior to …
