What are the two types of flux used in metallurgy?
The two types of flux used in metallurgy are acidic flux and basic flux. Acidic fluxes are used to remove impurities by forming acidic slag, while basic fluxes are used to form basic slag and improve the flow characteristics of the molten metal.
What is the process of smelting iron ore?
Iron ore is not normally smelted, instead it is reduced in a blast furnace with a mixture of coke & limestone. The coke burns removing the oxygen from the iron ore and melting the resulting iron. The limestone neutralizes acidic sulfur compounds and acts as a flux.
What are the fuel and flux for haematite ore?
Fuel is 'Coke' an impure form of carbon Flux is 'Limestone' used to 'soak-up' other unwanted materials in the reduction process. Also, Don't forget you also need HOT AIR'. Coke, Limestone and haematite ore are intimately mixed. Then charged into the Blast Furnce. Where a Blast of Hot air blows through the mixture. The first stage is that limestone thermally decomposes into calcium oxide (lime) and carbon dioxide. Concurrent the coke combines with the hit air to form more carbon dioxide. However, there is an excess of coke, so the carbon dioxide, is reduced to form carbon monoxide. The second part of the process is that carbon monoxide reacts with the haematite to reduce the haematite to iron, and carbon dioxide. The lime formed earlier reacts with any impurities present, notably silicon dioxide (sand) to form calcium silicate. Here are the reaction eq'ns. CaCO3 ==ht==> CaO + CO2 C + O2 = CO2 2CO2 + 2C(Excess coke) == 4CO 12CO + 4Fe2O3 = 12CO2 + 8Fe CaO + SiO2(Impurites) = CaSiO3 (Slag). The slag produced is used to make 'breeze blocks' for building , and for road surfaces.
How can borax be used in the process of extracting gold from ore?
Borax is used in the process of extracting gold from ore as a flux to help separate gold from other minerals. It helps to lower the melting point of the gold, allowing it to be easily separated from the ore.
Should you use borax when melting copper at home?
No, borax is not necessary for melting copper at home. It is commonly used in jewelry making to act as a flux to prevent oxidation, but it is not essential for melting copper in a basic home setup. Just ensure your melting equipment is clean and the copper is free from impurities to achieve good results.

What is a flux when making things?
Flux is any material used to aid in the purification of smelted metals and cleaning or joining of metal in welding. it is a Metallurgy term.
Is quicklime used in the manufacture of glass?
Yes, quicklime (calcium oxide) is sometimes used in the manufacturing of glass. It is used as a flux to help lower the melting point of the raw materials and facilitate the melting process.

How does the introduction of volatiles trigger melting?
The introduction of volatiles, such as water, lowers the melting point of rocks through a process called flux melting. As the volatiles mix with the solid rock, they disrupt the crystal lattice structure and weaken the bonds between atoms. This allows the rock to melt at lower temperatures than it would under normal conditions.
Where does flourine get its name?
The name is derived from the Latin word "fluores" with the meaning "which flow"; fluorine minerals were used in the past as flux in metallurgy.
