What is the role of flux in the metallurgy of iron & copper?

To remove basic FeO, silica (SiO2) is used as the acidic flux which combines with FeO to form fusicles ferrous silicate slag. …

What do you mean by flux?

The noun flux describes something that constantly changes. If your likes, dislikes, attitudes, dreams, and even friends are changing all the time, you may be in flux. Another kind of flux is liquid moving or flowing, like the flux of water under a sheet of melting ice.

What is flux in metallurgy Class 12?

Flux is the substance added during the extraction of metals. On heating it reacts with the earthly impurities(gangue) to form fusible (molten) mass known as slag. They may be acidic or basic in nature. Acidic flux are is used to remove the basic impurities. For example silica.

What is flux in chemistry definition?

Flux is a chemical purifying agent, flowing agent or cleaning agent. Most commonly, it is used in metal joining and metallurgy. Some examples of flux include: Ammonium chloride. Zinc chloride.

What is flux role?

The role of flux is typically dual: dissolving the oxides already present on the metal surface, which facilitates wetting by molten metal, and acting as an oxygen barrier by coating the hot surface, preventing its oxidation.

What is the role of flux in metallurgical?

flux, in metallurgy, any substance introduced in the smelting of ores to promote fluidity and to remove objectionable impurities in the form of slag. In soldering, a flux is used to remove oxide films, promote wetting, and prevent reoxidation of the surfaces during heating. …

What is flux in extractive metallurgy?

In metallurgy, a flux (derived from Latin fluxus meaning “flow”) is a chemical cleaning agent, flowing agent, or purifying agent. Fluxes may have more than one function at a time. They are used in both extractive metallurgy and metal joining. Iron ore was also used as a flux in the smelting of copper.

What is flux in hydrology?

Fluxes mean inflow- outflow water relationship. In order to define the water balance or water budget of an aquifer system of soil strata, the individual processes that bring water into or the liftoff of the system must be quantified.

What is the role of flux in metallurgical process?

flux, in metallurgy, any substance introduced in the smelting of ores to promote fluidity and to remove objectionable impurities in the form of slag. Limestone is commonly used for this purpose in smelting iron ores.

What is sand flux?

Sand flux is defined as the volume (or mass) of dune sand passing through a line of unit length perpendicular to the wind direction per unit time.

What is flux iron?

flux, in metallurgy, any substance introduced in the smelting of ores to promote fluidity and to remove objectionable impurities in the form of slag. Limestone is commonly used for this purpose in smelting iron ores. Other materials used as fluxes are silica, dolomite, lime, borax, and fluorite.

What is added as flux in extraction of iron?

In the blast furnace for extraction of iron, the flux added is limestone CaCO3.
