Reverberatory Smelting - 911 Metallurgist

Mar 09, 2017 · In reverberatory smelting, fuel is the chief item of expense, as it commonly is in processes using large percentages of it.Hence the most suitable supply is eagerly sought; that is, the supply which, in the end, yields the greatest net profit. The better grades are not infrequently bought, even at an advanced price, because they are apt to be decidedly more economical.

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.

What Is a Reverberatory Furnace? (with picture)

A reverberatory furnace melts metal-containing ore by generating hot gasses near the roof of the furnace without the metal ever coming into direct contact with the fuel source that is used to heat it. A reverberatory furnace is a type of smelting or metal-refining furnace that has been used since the mid-17 th century and is more commonly known ...

Reverberatory Furnace - University of Technology, Iraq

Reverberatory furnace, 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. The term reverberation is used here in a generic sense of rebounding or reflecting , not in the acoustic sense of echoing. ...

Reverberatory Furnace Design - The classification and ...

Reverberatory furnaces consisted of a wide concave hearth-bed, partially separated from an adjacent fireplace by a low partition wall (called the fire bridge), with a low arched roof (the fire arch) over all. Thus the main difference in the design of reverberatory and shaft furnaces was the separation of ore and fuel.

BACKGROUND REPORT SECONDARY COPPER SMELTING,

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.
