2. If your solder wick does not have flux on it, it would be a good idea to add flux to the section you are going to use to make for a clean removal. 3. Place the braid over the joint you want to rework. 4. Place a hot soldering iron against the braid and desired pin. 5. Wait a few seconds. The solder will flow off the pin and onto the braid. 6.

The first mention of the systematic extraction of copper ore comes from about 3800 B.C. when an Egyptian reference describes mining oxygen, iron, silica, and various organic compounds, depending on the process used. The silica flux reacts with the remaining iron to form a

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. Some of the earliest known fluxes were sodium carbonate, potash, charcoal, coke, borax, lime, lead sulfide and certain minerals containing phosphorus.

Define Iron Extraction by Blast Furnace Metallurgy? Iron, when extracted from iron ore such as haematite containing iron(III) oxide, Fe 2 O 3, in a blast furnace is called iron extraction blast furnace metallurgy.In this reduction reaction, oxygen is removed from the iron(III) oxide to leave behind iron.

The major steps in the extraction of copper are. Copper in Chalcopyrite is reduced to copper sulphide. Just like in Blast Furnaces, calcium carbonate is added as a flux to create the slag. Iron in Chalcopyrite is removed as iron silicate slag. Most of the sulphur in Chalcopyrite turns into Sulphur dioxide (SO 2).

Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel98% of the mined iron ore is used to make steel. In 2011 the Financial Times quoted Christopher LaFemina, mining analyst at Barclays Capital, saying that iron ore is "more integral to the global economy than any other commodity, except
