Melting of cathode copper in the reverberatory, the electric are furnace and the Asarco shaft furnace is analyzed in order to evaluate specific capacity, process fuel equivalent and the energy efficiency for each process. The Asarco furnace possesses considerably higher specific capacity and energy efficiency than the reverberatory as a result of the basic design for counter-current flow. The ...
The two types of flash furnaces currently in operation in the U.S. are Outokumpu furnaces and Inco furnaces. These furnace types represent 35 and 25 percent of U.S. primary copper smelting capacity, respectively. Both furnaces are constructed mainly of chromia-magnesia bricks (MgO and Cr 2O 3-MgO) surrounded by a steel shell. Because the ...
Apr 25, 1991 Multiple furnaces, analyzer cells, etc. may be employed but this is not generally economical. Referring to FIG. 2 which shows a shaft furnace having four (4) burners, in operation, a sample from mixer 15a will be taken and directed by valve 22a through line 23a to vacuum pump 23.
The iron blast furnace (Fig. 47) is the most highly developed shaft furnace and can operate very efficiently not only as a heating unit but as a high temperature reaction chamber.Modern furnaces are nearly 30 m high (plus a considerable superstructure) and may be over 15 m in diameter at the hearth.
The scrap copper is charged into the ASARCO shaft furnace via a top loading system. The copper is heated in the charging section by hot combustion gases from the gas burners. The copper gradually passes from the charge section to the melting section where a temperature of 1100C is maintained. The molten copper

Jun 14, 1999 The Asarco shaft furnace is predominately employed and the copper is placed in the furnace at the top and is heated and melted as it descends down the shaft. The heat is provided by impinging and ascending combustion gases produced in burners near the bottom of the furnace.

furnace process rate is controlled by the proportion of coke in the charge and by the air flow through the tuyeres in the floor of the furnace. The charge descends through the furnace shaft into the smelting zone, where it becomes molten, and is tapped into a series of settlers that allow the separation of lead from slag.

Electric Furnace Electric furnaces heat the charge by running a massive electrical current through it (the larger furnaces use approximately 20,000 amps at 50 to 500 volts). These work by immersing electrodes in the charge, as shown in Figure 4. Figure 1 Schematic of a shaft furnace, showing the material flows. Shaft Furnace Solids In
Jun 01, 2019 A Shaft-Electric Furnace for Melting and Smelting. The electric arc furnace has characteristics which make it attractive for a number of metallurgical applications. Some of these characteristics are high thermal efficiency, the possibility of attaining very high temperatures, low off-gas volume compared to fuel-fired furnaces, no impurities ...
tack. Shaft furnaces were loaded from the top with alternate layers of iron ore and charcoal. Molten slag was drawn off through an arched opening at the base of the shaft, draining away in channels and later solidi-fying into a lava-like appearance (Fig. 3). Shaft furnaces achieved a
copper rod. The holding furnace can be rotated up to 90 to increase or decrease copper flow into the lower launder and, by looking at the furnace position on the InTouch screen, the furnace operator can determine if hes gaining or losing on the amount of copper flow and can adjust the shaft firing rate accordingly.
Other articles where Shaft furnace is discussed iron processing History Stone-built shaft furnaces, on the other hand, relied on natural draft, although they too sometimes used tuyeres. In both cases, smelting involved creating a bed of red-hot charcoal to which iron ore mixed with more charcoal was added. Chemical reduction of the ore then occurred, but,

ASARCO shaft furnace, then continuously cast into copper bar and subsequently rolled into rod. Copper leaves the shaft furnace and is transferred to the holding furnace by means of a launder. Liquid copper continuously leaves the holding furnace, flows down a second launder and then enters the pour pot.
