Reverberatory Furnace | PDF | Smelting | Chemical Elements
The reverberatory furnace is used in smelting copper and other metals. It consists of a brick-lined hearth where the ore is melted. Heat is transferred to the ore via hot gases from a firebox that reverberate off the arched roof and back into the hearth. The ore is charged into the furnace and melted over 16 hours, separating the molten metal from slag impurities that are skimmed off. …

reverberatory and shaft furnaces was the separation of ore and fuel. Long-flame fuels such as pit coal replaced charcoal, and heat from the fuel was reflected onto the bed by the curved roof. …
Reverberatory Furnace: Working, Applications, …
In copper, tin, and nickel production, a reverberatory furnace is a smelting or refining furnace in which the fuel does not come into direct contact with the ore but is heated by a flame blasted over it from another chamber.
DF2014:Cassiterite
Smelting . Cassiterite is a required ingredient to make several types of metal alloy bars from ore at a smelter: Tin bars; Bronze bars - with native copper, malachite, or tetrahedrite; Trifle pewter bars - with native copper, malachite or tetrahedrite (takes 2 cassiterite) Fine pewter bars - with native copper, malachite or tetrahedrite (takes ...
Insight into the Extractive Metallurgy of Tin from Cassiterite
Cassiterite (SnO 2) is the most economically viable minerals for extracting tin among the over fifty minerals that host the metal [1,2,3,4].Being the only oxide mineral, its theoretical tin content is 78.77%; however, in the ore form, the metal may show a value between 0.4 and 1.5% [1,5].Considering primary sources, cassiterite finds itself as the main source of …
Reverberatory furnace | Smelting, Refining, Alloying
reverberatory furnace, in copper, tin, and nickel production, a furnace used for smelting or refining in which the fuel is not in direct contact with the ore but heats it by a flame blown over it from another chamber. In steelmaking, this process, now largely obsolete, is called the open-hearth process.The heat passes over the hearth, in which the ore is placed, and then reverberates back.

What is Smelting?
Cassiterite: 2SnO 2 + 2C = 2Sn + 2CO 2; Silver oxide: 2Ag 2 O + C = 4Ag + CO 2; Minium: 2PbO + C = 2Pb + CO 2; Smelting vs. Melting. Smelting should not be confused with melting, as melting at high temperatures without the use of a reducing agent will produce molten ore but will not melt the metal out of the ore.
Extraction of metal from the ore cassiterite involves
Tin is obtained by reducing the ore cassiterite with coal in a reverberatory furnace; limestone is added to produce a slag with impurities, which can be removed. S n O 2 + 2 C S n + 2 C O. Crude tin so obtained is contaminated with iron, lead, and other metals. It is, therefore, remelted on an inclined furnace. The process is called liquation.
