How does iron ore look like?
There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red.

How can you tell if a rock is iron ore?
Streak: if you scratch a meteorite on an unglazed ceramic surface, it should not leave a streak. A dense rock that leaves a black or red streak probably contains the iron minerals magnetite or hematite, respectively, neither of which are typically found in meteorites.
What is ore rocks?
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.

How can you tell if a rock is gold ore?
You're looking for a scratch on the glass. If the glass gets scratched from the 'gold', it's not actually gold. Since glass has a hardness of around 5.5 it will only be scratched by harder minerals like pyrite and quartz. If the glass doesn't scratch then that's a great sign – you likely have gold in your rock!
What is ore made of?
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.
How is ore 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.

Features. The absence of cleavage with the ore's gold is a notable feature. Evidence of quartz and sulfide minerals surrounding gold veins may be clear. Gold ore can look like quartz with streaks or spotty areas of gold.
What is the most common ore?
Hematite and magnetite are by far the most common types of ore. Pure magnetite contains 72.4 percent iron, hematite 69.9 percent, limonite 59.8 percent, and siderite 48.2 percent, but, since these minerals never occur alone, the metal content of real ores is lower.

Ore can accumulate through geologic activity, such as when volcanoes bring ore from deep in the planet to the surface. This is called an internal process. Ore can also accumulate when seawater circulates through cracks in Earth's crust and deposits minerals in the areas around hydrothermal vents.
Where can I find ore deposits?
To find a mineral deposit, geologists study the geology of a lot of places. They then go to a spot where that type of mineral deposit could be found. They test the properties of the soil and rocks. They look at the chemistry and the physical properties.
What are the signs of gold in the ground?
Lighter Colored Rocks: If you notice out-of-place colors in a group of rock formations, it can be a gold indicator. Acidic mineral solutions in gold areas can bleach the rocks to a lighter color. Presence of Quartz: Quartz is a common indicator that gold MAY be nearby.
