Which mineral is an ore of iron and has a characteristic of reddish brown streak?
The mineral is hematite.
Which physical property would be best to use to distinguish hematite from the other mineral?
Streak
Which group of minerals is streak most useful for?
The colour of the streak left by a mineral is one of the features used to identify it. For instance, haematite leaves a red streak, malachite leaves a light green streak, while quartz, calcite and gypsum all leave a white streak.
What test would you perform to distinguish hematite form copper how would you carry out this test?
A few things used to identify minerals are streak tests, hardness, cleavage, solubility, magnetic.Streak test: When you scrape a mineral on a streak plate it leaves behind powder of a certain color. Hematite leaves a red streak. I don't know what streak copper has.Hardness test: minerals have different hardness, their ability to be scratched or scratch. this can be determined by seeing if you can scratch a mineral with your finger nail or if the mineral will scratch a piece of glass. I don't know if this test will do much good though in determining copper from hematite.Cleavage: Cleavage in mineralogy refers to when you break a mineral, how it fractures. Does it fracture into cubes, rhombus shapes, conchoidal, etc.Solubility: copper is soluble in acids and forms green-blueish solutions, hematite is insoluble.Magnetic: hematite is sometimes slightly or strongly magnetic. copper is not magneticAfter you test your samples, look up in a book or manual to see which mineral(s) have matching properties.
How can you tell the difference between hematite and pyrite?
The difference between the iron in magnetite and hematite is the charge. Hematite has all 3+ iron ( the iron when make the mineral loses 3 electrons) and magnetite has some 2+ iron (it only loses 2 electrons).
Does hematite have a streak?
Hematite has a dramatic red streak.
What color of streak is produced by galena and hematite?
Galena's streak is gray, hematite's streak is deep maroon/brown.
Which is a good way to tell the difference between hematite and galena?
galena leave dark grey streak on streak plate where as hematite leave cherish red streak.
What is the mineral that leaves a grey streak and is metallic?
Hematite can appear gray in color, but will exhibit a reddish to rust-colored streak.
How can the streak test be used to identify limonite and hematite?
Hematite has a red streak. It can vary in depth of color, depending on the variety of hematite. Limonite has a yellow-brown (more brown than yellow) streak. But you have to make sure you are streaking the limonite and not an underlying mineral, if the limonite is located on another mineral.
What is the streak color for hematite?
It is red. Or brown. Either one. Sorry, I tested and it was brown but websites all say blood-red. So.. idk.. srry.
How can the streak test be used to identify the two iron minerals limonite and hematite?
Hematite has a red streak. It can vary in depth of color, depending on the variety of hematite. Limonite has a yellow-brown (More brown than yellow) streak. But you have to make sure you are streaking the limonite and not an underlying mineral, if the limonite is located on another mineral.
Which is an example if a mineral whose streak cannot be determined with a porcelin streak plate?
Hematite, gold, feldspar or magnetite
Which mineral is an ore of iron and has a characteristic of reddish brown streak?
The mineral is hematite.
Which physical property would be best to use to distinguish hematite from the other mineral?
Streak
What can you rub a mineral on to leave a clue what the mineral?
A streak plate, or unglazed white porcelain tile, is used to perform streak tests which can help to identify minerals. Rubbing the mineral on the streak plate will finely powder it and reveal the color of the powder, which in some cases is quite different from the color of the mineral. Eg: hematite is black but has a red streak - a good way to tell you have hematite instead of one of the many other shiny black minerals.
This mineral is the most common iron oxide mineral Most are red with an earthy luster It has a crumbly fracture and leaves a red brown streak?
Hematite.
