oxide to metal. So, for example, solid carbon can reduce chromium oxide once the temperature exceeds approximately 1225°C, and can even reduce highlystable compounds like silicon dioxide and titanium dioxide at temperatures above about 1620°C and 1650°C, respectively. For less stable oxides, carbon monoxide is often an adequate reducing agent.
quartz, which is composed of silica (silicon dioxide). Other components may include aluminium, feldspar and ironbearing minerals. Sand with particularly high silica levels that is used for purposes other than construction is referred to as silica sand or industrial sand.

Iron ores are rocks and mineral deposits from which clanging iron can be reasonably extracted. Iron ore mining is classified into two categories manual mining and mechanized mining methods. Haematite and magnetite are the most commonly found iron ore minerals. Deposits of iron ore such as haematite containing iron oxide are found in sedimentary rocks from which the oxygen is removed from the ...

Silicon dioxide, also known as silica, is an oxide of silicon with the chemical formula Si O 2, most commonly found in nature as quartz and in various living organisms. In many parts of the world, silica is the major constituent of is one of the most complex and most abundant families of materials, existing as a compound of several minerals and as synthetic product.
Silicon dioxide or silica, as it is commonly known as, is an important constituent of sand. However, it is found in several other forms too. In this article, we shall look into the physical and chemical properties of silicon dioxide, and learn a little about its molecular structure.
EXTRACTION OF IRON IN A BLAST FURNACE Iron is also below carbon in the reactivity series, so therefore carbon can be used to reduce it (note: reduction can also mean to remove the oxygen from a compound). This is done in a blast furnace. The most common ore of iron is called haematite (iron(iii) oxide). Its formula is Fe 2 O 3.
In dry oxygen, iron readily forms iron(II) oxide, but the formation of the hydrated ferric oxides, Fe 2 O 3−x (OH) 2x, that mainly comprise rust, typically requires oxygen and water. Free oxygen production by photosynthetic bacteria some billion years ago precipitated iron out of solution in the oceans as Fe 2 O 3 in the economically important iron ore hematite.
