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.
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.
Developed in the 1980s the Asarco shaft furnace, an efficient copper melting furnace and reatrol technology to improve current efficiency and cathode quality. Exploration and development of the Troy mine and Rock Creek project in Northeastern Montana and the Camp Caiman gold exploration project in French Guiana.

12.3 Primary Copper Smelting 12.3.1 General1 Copper ore is produced in 13 states. In 1989, Arizona produced 60 percent of the total U. S. ore. Fourteen domestic mines accounted for more than 95 percent of the 1.45 megagrams Mg
A furnace consisting of several round, stacked hearths. The hearths are basically floors within a large cylinder. The hearths alternate between in-hearths and out-hearths. In hearths have a large hole in the center, for material to pass through to the hearth below. Out-hearths, have holes around the perimeter of the hearth for material to pass through to the hearth below.
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.
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 ...
Melting Furnace 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
THE HEART OF THE MIDREX PROCESS IS THE MIDREX SHAFT FURNACE. AS A KEY COMPONENT OF THE MIDREX DIRECT REDUCTION PROCESS, THE MIDREX SHAFT FURNACE IS THE MOST FLEXIBLE AND VERSATILE REDUCTION VESSEL FOR DRI PRODUCERS. The MIDREX Shaft Furnace can use natural gas or a syngas from coal or coke oven gas as its reductant.
Shaft Furnace of 1300mm hearth diameter, ef-fective height of 2.6m, useful volume of 7.3m3 provided with four tuyeres, details of which have been outlined earlier.23 Sections through shaft, hearth and the furnace profile are shown in Fig. 1. Chemical Analysis of Raw Materials
The forging furnace is used for preheating billets and ingots to attain a forge temperature. The furnace temperature is maintained at around 1200 to 1250 oC. Forging furnaces use an open fireplace system and most of the heat is transmitted by radiation. The typical load is 5 to 6 ton with the furnace
The experience of operating the shaft furnace with a diameter of 6.5m has led to the construction of a larger shaft furnace at Saudi Iron amp Steel Company in Hadeed, Saudi Arabia in 2007. This shaft furnace has a diameter of 7.15m and an increased production capacity of 1.8 million tonnesyear Fig. 7. Another shaft furnace, SUPER MEGAMOD,

The slag produced in the shaft furnaces of the Trep a metallurgical corporation during the smelting of agglomerates contains a considerable quantity of valuable metals, such as Pb, Zn, Bi, Ag, Au.
The shaft furnace, which is a scrap melting furnace, plays an important part as an energy supplier in a steel works because the shaft furnace produces high calorie gas. The shaft furnace is required either to reduce the coke rate or to increase the exhaust gas calorie, corresponding to the energy balance in the steel works.
In the shaft of the furnace, the charge is heated to 873 K. According to 6, at a temperature of 773 873 K, the thickness of the oxide f ilm is 2 10 -7 m .
