Ore is natural rock or sediment that contains one or more valuable minerals, typically metals, that can be mined, treated and sold at a profit. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. Classification of Ore

A mineral is a naturally occurring crystalline solid that cannot be physically broken down into smaller components.. Deposits of minerals form when a medium that contains and transports mineral-making ore releases and deposits the ore. Magma is one such medium that transports ores. When magma or lava cools, the magma and ore carried within it crystallize to form tiny minerals in the newly ...

2021-2-4 U.S. Geological Survey, Mineral Commodity Summaries, January 2021 . IRON ORE . 2020 was $84.73 per ton in April compared with the low of $76.16 per ton in January 2019. The prices trended upwards owing to a reduced supply of higher grade iron ore products, spurred partially by closures of pelletizing plants in Brazil.

Native gold is an element and a mineral. It is highly prized by people because of its attractive color, its rarity, resistance to tarnish, and its many special properties - some of which are unique to gold. No other element has more uses than gold. All of these factors help support a price of gold that is higher than all but a few other metals.
