They are rocks that are chemical compounds of useful metals with nonmetallic elements such as oxygen or sulfur. They are purified with chemical methods that take away the impurity. For example, carbon monoxide removes oxygen (forming carbon dioxide) from iron ores (which are different types of rust- compounds of oxygen and iron).
Those ores which contain metal in the form of oxides are called as oxide ores.
No, metal ores occur naturally in the Earth.
smelting is used for sulfide ores. Iron ores require a blast furnace. aluminum ores require high temperature electrolysis. etc. it varies by type of ore and metal.
Gold generally is found in its elementary state, so it has no ores
no
Those ores which contain metal in the form of oxides are called as oxide ores.
oil, methane gas, coal, wood, mercury, iron ores, copper ores, zinc ores, lead ores
Extraction of metals from its ores and formation of ores. Studying their properties, their alloys,refining of ores.
Ores.
Their importance is that these ores can be extracted into metals .
Ores are finite, yes.
Francium hasn't ores; infinitesimal amounts of francium exist in some uranium ores.
ores must be nonrenwable
Metal ores are used as resources from which metals may be extracted.
yes , sulphur have ores. such ores are called sulphide ores. these sulphide ores are purified by the process called roasting. this is the process which involves heating with oxygen and then reducing into original metals. eg: copper sulphide, zinc sulphide, etc.
Uranium and zirconium ores
Diamonds are formed from carbon and contain no ores.
