The presence of significant amounts of metal compounds in the rocks.
ore
Metal-bearing rocks are called ore. They contain valuable metals that can be extracted and refined for various industrial purposes. Examples include iron ore, copper ore, and gold ore.
an ore has a metal inside it with economic value inside it that makes it different from any other normal rocks, if it has economic value t will obviously be quite alot of the metal in the ore and it will be quite heavy and will most likley be heavier than other rocks. hope that helped, sorry for long answer :(
Ore grinder is a kind grinding mill to grind the ore, rocks, stones, minerals into powder.
Because it depends on what type of ore it is. If it is a certain type of ore, then there is a certain amount of value in money for it. That's Why.
ores are rocks that are mined
Granite ore, and magnesium peroxide
From their ore's, ie from their individual mineral bearing rocks.
Rocks, water, ore etc
igneous rocks- rocks that are formed from melted minerals. ore-a rock that has a large amount of minerals.
Copper ore is typically found in igneous rocks, such as basalt or granite, as well as in sedimentary rocks like shale. The most common type of rock where copper ore is extracted is called porphyry copper deposits, which are a combination of igneous and sedimentary rocks. These rocks contain copper minerals like chalcopyrite, bornite, and chalcocite, which are essential for copper extraction.
Gems are valuable rocks aren't.
