Is hematite a mineral element?
Hematite is a mineral. This is from wikipedia: A mineral is a naturally occurring solid with a definite chemical composition and a specific crystalline structure. A rock is an aggregate of one or more minerals. Have a look at this page in wiki about hematite: http://en.wikipedia.org/wiki/Haematite
Is coal a element compound or mixture?
Coal is a mixture, as it is composed of a variety of organic compounds, minerals, and other substances. It is not a single chemical element or compound.
Is it true that both carbonates and oxides are minerals that contain the element oxygen?
Yes, that is true. Carbonates, such as calcite and dolomite, and oxides, such as hematite and magnetite, are mineral groups that contain the element oxygen as part of their chemical structure. Oxygen commonly combines with other elements to form minerals in Earth's crust.
Is hematite soluble?
not soluble in water but in ethanol or other alcohols.
How hematite ore is concentrated?
Hematite ore is concentrated through a process called magnetic separation. In this process, the powdered hematite ore is passed through a magnetic separator to separate the iron oxide from other impurities. This results in a higher concentration of iron oxide in the final product, which can then be further processed into iron.
Is iron ore a mineral?
There are a variety of iron ores such as the minerals limonite, hematite, magnetite, that are rich in the element iron and mined extensively for the production of iron and steel.. These minerals, in addition to iron, contain other elements.
Is hematite a mineral element?

Can other minerals scratch the hematite?
Yes, other minerals can scratch hematite. Hematite has a hardness of 5.5-6.5 on the Mohs scale, so minerals with a higher hardness (like quartz or corundum) can scratch hematite.
Is hematite and feldspars are exapmles of native elements?
No, hematite and feldspars are not examples of native elements. Hematite is an iron oxide mineral (Fe₂O₃), and feldspars are a group of silicate minerals that contain aluminum and various other elements, such as sodium, potassium, or calcium. Native elements are minerals that consist of a single element, such as gold, silver, or copper.
How to separate hematite from other rock and mud?
A relatively new process, magnetation, will aid in the separation of hematite from other rock. Used in the waste tailing of iron ore mining, the magnets attract the hematite for use.
How strong is hematite compared to other minerals?
Hematite is considered to be moderately strong compared to other minerals. It has a hardness rating of 5.5-6.5 on the Mohs scale, which measures a mineral's resistance to scratching. This places hematite in the middle range of mineral hardness.
Which physical property would be best to use to distinguish hematite from the other minerals in the table?
The best physical property to distinguish hematite from other minerals is its characteristic reddish-brown streak. When powdered, hematite leaves a streak that is typically a reddish hue, which is distinct from many other minerals. Additionally, hematite has a metallic to earthy luster and a hardness of about 5.5 to 6.5 on the Mohs scale, which can also aid in identification.
What element other than Carbon has atoms that will react with other elements to form a variety of compounds?
There are very many elements which will do that.
Is coal a element compound or mixture?
Coal is a mixture, as it is composed of a variety of organic compounds, minerals, and other substances. It is not a single chemical element or compound.
Is hematite found in Michigan?
Yes it is and in other places around the world.
Which physical property would be best to use to distinguish hematite from the other mineral?
One physical property that can be used to distinguish hematite from other minerals is its streak color. Hematite typically leaves a reddish-brown streak when scratched against an unglazed porcelain plate. This can help differentiate it from other minerals that may have different streak colors.
What country produces the most hematite?
China is the country that produces the most hematite in the world. Second to China, the country of Brazil also has a very large hematite production level.
