鐵礦石是可從中提取金屬鐵的岩石和礦物。 礦石通常含有豐富的氧化鐵，顏色從深灰色，亮黃色或深紫色到生鏽的紅色。 鐵本身可找到磁鐵礦，赤鐵礦，針鐵礦，褐鐵礦或菱鐵礦等的形式。 其化學式是Fe2O3。

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, or deep purple to rusty red. The iron itself is usually found in the form of magnetite, hematite , goethite, limonite  or siderite . Its chemical formula is Fe₂O₃.

它是沉積岩。 它由海洋和淡水中的鐵和氧結合的化學反應，通過氧化過程形成。 它是交替層次的富含鐵質的礦物質

It is sedimentary rock. It formed by chemical reactions that combined by iron and oxygen in marine and fresh waters, by the process of oxidation.  And it is alternating layers of iron-rich minerals

鐵是在地殼中第二豐富的金屬。

當鐵暴露在空氣中時，它開始變回氧化鐵，形成在鐵表面上的紅色粉末就是我們所說的銹。 你可能在舊車或舊鐵棚或屋頂上看到生鏽。 為了使鐵更堅固，更不容易生鏽，它可以與碳和其他元素結合來製造鋼。

礦物磁鐵礦是非常有磁性的，如果你在一段長度的繩子上擺放一塊，它將自己定向南北。 鐵和一些鐵合金也是磁性的。

Iron is the second most abundant metal in the Earth’s crust.

When iron is exposed to the air it starts to turn back into iron oxide and the red powder that forms on the surface of iron is what we call rust. You may have seen rust on old cars or old iron sheds or roofs. To make iron stronger and less likely to rust it can be combined with carbon and other elements to make steel.

The mineral magnetite is very magnetic, and if you dangle a piece on a length of string it will orient itself north-south. Iron and some alloys of iron are also magnetic.

鐵礦石的用途是可以生產鐵。 大部分生產的鐵都是用以煉鋼。 鋼是用於製造汽車，機車，船舶，建築物中使用的橫梁，家具，回形針，工具，混凝土用鋼筋，自行車以及數千種其他物品。 它是噸位最常用的金屬。

The use of iron ore is in to produce iron. Most of the iron produced is is to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items. It is the most-used metal by both tonnage and pu.

分佈靠近火山或一些高山，是沉積岩。 它也可以在地球核心和地殼中找到.香港的四大礦山為蓮麻坑鉛礦, 針山鎢礦, 馬鞍山鐵礦, 大磨刀洲石墨礦.

The distribution is near the volcanos or some high hills .It is sedimentary rock. It can been found in the core of the Earth and in the Earth’s crust

The four major mine in Hong Kong are The Lin Ma Hang Lead Mine,The Needle Hill Tungsten Mine,The Ma On Shan Iron Mine, The West Brother Graphite Mine

馬鞍山鐵礦是香港最大的礦山。

Ma On Shan Iron Mine is the biggest mine in HK.
