  • Smelting Wikipedia

    Smelting is a process of applying heat to ore in order to extract a base metal.It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a stone reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

  • Smelting Furnace an overview ScienceDirect Topics

    The smelting furnace generates process gas streams with SO 2 concentrations ranging from 0.5% to 80%, depending on the process used. It is important, therefore, that a process be selected that uses oxygen-enriched air (or pure oxygen) to raise the SO 2 content of the process gas stream and reduce the total volume of the stream, thus permitting

  • Copper processing Roasting, smelting, and converting

    Copper processing Copper processing Roasting, smelting, and converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined furnace of either the hearth or

  • Flux (metallurgy) Wikipedia

    Some of the earliest known fluxes were sodium carbonate, potash, charcoal, coke, borax, lime, lead sulfide and certain minerals containing phosphorus. Iron ore was also used as a flux in the smelting of copper. These agents served various functions, the simplest being a reducing agent, which prevented oxides from forming on the surface of the molten metal, while others absorbed impurities into

  • Lead smelting Wikipedia

    Ancient smelting was done using loads of lead ore and charcoal in outdoor hearths and furnaces. Although lead is a common metal, its discovery had relatively little impact in the ancient world. It is too soft to be used for weapons (except possibly as sling projectiles) or for structural elements.

  • CN102220440A Vanadium-titanium magnetite blast furnace

    The invention discloses a vanadium-titanium magnetite blast furnace smelting method capable of improving vanadium yield, belonging to the field of metallurgy, and is mainly used for solving the problem of low vanadium yield during vanadium-titanium magnetite blast furnace smelting. The vanadium-titanium magnetite blast furnace smelting method capable of improving vanadium yield comprises the

  • What Are the Different Types of Smelting Furnaces?

    Aug 01, 2020· The electric furnaces vary from the induction-style smelting furnaces in that carbon rods are heated using electricity to create the right temperature for smelting. The carbon rods are capable of producing a higher temperature than the electricity alone; along with the carbon rods, granite rods are also used to create the desired heat to complete the smelting process.

  • Zinc Smelting an overview ScienceDirect Topics

    Many processes give rise to combustible gases, often of low calorific value, yet capable of useful work if correctly applied. In addition to blast furnaces and coke ovens, iron cupolas, zinc smelting furnaces and electric-arc melting furnaces all yield combustible gases. Quite an appreciable amount of methane is recovered from upcast air from

  • Bloomery Wikipedia

    A bloomery is a type of furnace once used widely for smelting iron from its oxides.The bloomery was the earliest form of smelter capable of smelting iron. Bloomeries produce a porous mass of iron and slag called a bloom.The mix of slag and iron in the bloom, termed sponge iron, is usually consolidated and further forged into wrought iron. Blast furnaces, which produce pig iron, have largely

  • Zinc: smelting, producing and classification-Metalpedia

    Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. The most common zinc concentrate processed is zinc sulfide, which is obtained by concentrating sphalerite using the froth flotation method.There are two methods of smelting zinc: the pyrometallurgical process and the hydrometallurgical process (over 90% of hydrometallurgical process is in

  • The Smelting of Copper University of Worcester

    The Smelting of Copper The first written account of the processes of smelting and refining of copper is to be found in the 12th century.1 On smelting: Copper is engendered in the earth. When a vein of which is found, it is acquired with the greatest labour by digging and breaking. It is a stone of

Furnace designs: Tools and materials: Hefty Harriette It was time to "crank it up a few degrees" literally and figuratively and build a big furnace capable of withstanding repeated iron melts.

  • Crucibles: Amazon

    Crucibles are cup- or bowl-shaped containers used for mixing and heating substances in high-temperature, corrosive, or pigmentation applications. They vary in height such as low, mid, and high forms, and they also vary in capacity. Crucibles are made of various materials depending on the temperature requirement of the application.
