Smelting of low-grade copper scrap begins with melting in either a blast or a rotary furnace, resulting in slag and impure copper. If a blast furnace is used, this copper is charged to a converter, where the purity is increased to about 80 to 90 percent, and then to a reverberatory furnace, where copper of about 99 percent purity is achieved.
Mar 05, 2017· Copper Smelting Furnace. The early development of the reverberatory furnace for smelting copper ores was the work of the Welsh smelters, particularly those of Swansea. The first record of a reverberatory furnace is made by Jars, who states that copper-smelting was effected in reverberatory furnaces at Middleton-Tyas, in Yorkshire, England.
Mar 18, 2016· The Pao Tai Mining & Smelting Co. The reverberatory furnace, shown in Fig. 6, can dead-roast 1975 lb. (895 kg.) of crude per 24 hr., with a consumption of 755 lb. (342 kg.) of coal. Two men are required per furnace per shift of 12 hr. The roasted crude, i.e., the tetroxide, after having been mixed with 15 per cent, charcoal and 5 per cent, soda ...
furnaces must be dry for reasons that will be discussed below, rotary, flash, fluidized-bed, and spray dryers are used in conjunction with these furnaces to obtain a feed containing no more than 0.2 percent water by mass. The Outokumpu flash smelting furnace is characterized by five major components:
SCOPE: Smelting of lead-bearing materials (paste, metallic) with fluxes TYPE: Tilting 45° with double pouring system: 1) metal from dedicated channel with furnace in horizontal position and 2) slag from feeding port via furnace tilting Details include: - Refractory Material of Chrome-Magnesium basis - Oxy-fuel burner or air-fuel burner.
May 05, 2017· This smelting furnace handled all off-grade slags and mattes, together with any residue of zinc dust not liquefied in the rotary furnace and the various residues from the refining furnaces. The furnace operated in the smelting zone at a temperature above 1,400° C. (2,523° F.), and lead and zinc were volatilized and left the furnace in vapor ...
USAC has resumed the production of high purity antimony metal at its Madero smelter and is expediting the installation of two more large rotary furnaces (LRFs) from Reynosa. Each furnace will be capable of roasting 4 to 5 metric tons of Wadley ore per day or 5 to 7 metric tons per day of concentrate from Guadalupe or Los Juarez.
Dec 01, 2019· In our previous work (Ye et al., 2015), a molten salt smelting process was adapted to the smelting of stibnite in molten NaCl–Na 2 CO 3 systems at 600–900 °C, and metallic Sb was obtained in one-step. The significant advantages were the low temperature and sulfur fixation, although the consumption of molten salt was significant.
Rotary reverberatory furnace, also named as anode furnace, is especially used to treat copper scrap (Cu 92% and above) to get copper anode (Cu 99%), which can be further purified by electrorefining to produce 99.99% Cu cathode. The copper cathode can be processed by upward casting machine to standard copper rod.

Propane furnaces do not require any power and can be used on the go. They are excellent for melting gold, silver, copper, brass, aluminum, and other metals. Take your melting to a professional level with our induction furnaces which use controlled, localized heat to melt your materials. Capable of reaching temperatures of 2300°F+.
Rotary Furnace. In rotary furnaces, the burners heat the top refractory, which rotates under the charge. Due to lower stack losses, such furnaces are more efficient than reverberatory furnaces and are used primarily to melt scrap containing less than 70% aluminum. Dross and slag may also make up the feed to a rotary furnace.
Oct 25, 2016· The rotary kiln-electric furnace process is the one of the most widely adopted technological process for ferronickel smelting production. A schematic of the RKEF process with rotary dryer, rotary kiln and electric furnace is shown in Fig. 1.As depicted, the RKFF process involves three main processes: the dehydration process in rotary dryer; the roasting and pre-reduction process in rotary …
Rotary furnaces are usually used to process low-lead-content scrap and residue, while reverberatory furnaces are used to process high-lead-content scrap. The partially purified lead is periodically tapped from these furnaces for further processing in smelting furnaces or pot furnaces. 12.11.2.2 Smelting -
Slag Of Gold-Antimony Ore Blast Furnace Smelting Has Seldom Been Studied. In This Paper, The Viscosities Of Gold-Antimony Ore Smelting Slags Of Different Composition Have Been Studied By The Rotating Cylinder Method. The Results Showed That, For A Slag Of 38.95% Sio 2,
