Coat of arms of Cyprus Coat of arms of Cyprus The coat of arms of the Republic of Cyprus depicts a dove carrying an olive branch (a well-known symbol of peace) over “1960”, the year of Cypriot independence from British rule. The background is a copper-yellow colour; this symbolises the large deposits of copper ore on Cyprus (chiefly in the form of chalcopyrite, which is yellow in colour). The arms is not violating the rule of tincture, since the dove is not argent (silver) but blazoned as of the colour proper, i.e. it has the colour it would have in nature, in this case white.
Iron ore it some other desirable quality. The choice of ore, fuel, and flux determine how the slag behaves and the operational characteristics of the iron produced. Ideally iron ore contains only iron and oxygen. In reality this is rarely the case. Typically, iron ore contains a host of elements which are often unwanted in modern steel. Silica () is almost always present in iron ore. Most of it is slagged off during the smelting process. At temperatures above 1300 °C some will be reduced and form an alloy with the iron. The hotter the furnace, the more silicon will be present
