Ore
Rock with valuable metals, minerals and elements / From Wikipedia, the free encyclopedia
Dear Wikiwand AI, let's keep it short by simply answering these key questions:
Can you list the top facts and stats about Ore deposit?
Summarize this article for a 10 year old
Ore is natural rock or sediment that contains one or more valuable minerals concentrated above background levels, typically containing metals, that can be mined, treated and sold at a profit.[1][2][3] The grade of ore refers to the concentration of the desired material it contains. The value of the metals or minerals a rock contains must be weighed against the cost of extraction to determine whether it is of sufficiently high grade to be worth mining and is therefore considered an ore.[4] A complex ore is one containing more than one valuable mineral.[5]

Minerals of interest are generally oxides, sulfides, silicates, or native metals such as copper or gold.[5] Ore bodies are formed by a variety of geological processes generally referred to as ore genesis and can be classified based on their deposit type. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals.[4] Some ores, depending on their composition, may pose threats to health or surrounding ecosystems.
The word ore is of Anglo-Saxon origin, meaning lump of metal.[6]
