What is required for rocks to be considered ores?
Ore is natural rock or sediment that contains one or more valuable minerals, typically containing 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.
What is considered an ore?
Ore is a deposit in Earth's crust of one or more valuable minerals. The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron.
What is an ore and why might a rock become one?
An ore is a naturally occurring deposit of geologic material (rock) that includes a sufficient quantity of one or more valuable elements or compounds that it can be extracted for economic gain. These valuable elements include metals like copper, platinum, iron, lead, gold, silver, aluminum, nickel, and many more.
What characteristics must a rock have to be called ore quizlet?
What characteristics must a rock have to be called ore? The metallic mineral concentration must be enough to provide economic value. The rock must contain no more than two minerals, and the lesser must be easily removed by smelting.
How do you identify an ore?
Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.
How ores are formed?
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-created igneous rock.

What determines if a mineral deposit can be classified as an ore?
A mineral deposit that is sufficiently rich to be worked at a profit is called an ore deposit, and in an ore deposit the assemblage of ore minerals plus gangue is called the ore.
What 4 criteria must be met for something to be classified as a mineral?
Minerals are natural: These substances that form without any human help. Minerals are solid: They don't droop or melt or evaporate. Minerals are inorganic: They aren't carbon compounds like those found in living things. Minerals are crystalline: They have a distinct recipe and arrangement of atoms.
What features do geologists look for when the prospect for ores?
what features do geologists look for when they prospect for ores? geologists look for rocks on the land surface and by studying maps of rocks beneath the surface. geologists also look for magnetic fields.

How are ores formed quizlet?
ore forms when magma cools and dense metallic minerals sink. These sinking minerals accumulate at the bottom of the magma chamber forming ore deposits. 3. contact metamorphism can also form ore deposits when hydrothermal solutions (hot fluids) move through small cracks in a large mass of rock.
