US Patent for Cupola furnace to enable continuous

Use of a shaft kiln in continuous smelting and refining of cement copper is made possible with a mix preheater, a refined gas preheater, an air preheater, an air mix feeder and forehearths for cement oxidation and reduction, and wherein oxidation is achieved by injecting oxidant gases and reduction by injecting preheated petroleum gas, subsequent to having placed a layer of charcoal on the smelt.

Cupola Furnace: Working principle, Construction ...

Working Principle of Cupola Furnace: The Cupola furnace works on the principle where we generate heat from burning coke and when the temperature of the furnace is above the melting point of the metal then the metal is melt.. The charge introduced in the cupola consists of pig iron, scrap, casting rejection, coke, and flux.Coke is the fuel and limestone are added as a flux to remove undesirable ...

Cupola furnace - en.LinkFang

Cupola furnaces were built in China as early as the Warring States period (403–221 BC), although Donald Wagner writes that some iron ore melted in the blast furnace may have been cast directly into molds.During the Han Dynasty (202 BC – 220 AD), most, if not all, iron smelted in the blast furnace was remelted in a cupola furnace; it was designed so that a cold blast injected at the bottom ...

An Overview of Copper Smelting in Southern Africa

2015-6-18  indicates that the ore contained an average of 32% copper, and that cupola furnaces were in place. Production by the Cape Copper Company ceased in 1919 as a result of the post-war economic slump, and Okiep soon became a ghost town. The operations of the Namaqua Copper Company continued for slightly longer, but its mines finally closed in 1931.
