Question

Write four types of iron ores?

Answer 1

Iron-ore mining methods vary by the type of ore being mined. There are four main types of iron-ore deposits worked currently, depending on the mineralogy and geology of the ore deposits. These are magnetite, titanomagnetite, massive hematite and pisolitic ironstone deposits.

Answer 2

Answer:

Hematite, Magnetite, Limonite and Siderite.

Explanation:

1. The major iron ores are Hematite, Magnetite, Limonite and Siderite.

2. Hematite is red in colour and has 70% of iron content; best quality which makes it an important ore.

3. Magnetite is black in colour and has 70% of iron content.

4. Limonite has yellow shade and inferior quality having 40% to 60% of iron. It is present in open cast mines.

5. Siderite has inferior quality having less than 40% iron. It has impurities which makes it economically unviable.
