Question

How many of the following are oxide minerals of iron? Haematite, iron pyrites, siderite, magnetite, limonite (A)  (B)  (C)  (D)

Tardigrade Admin · Accepted Answer

Haematite ( Fe 2 O 3), magnetite ( Fe 3 O 4) and limonite (2 Fe 2 O 3 .3 H 2 O ) are oxide minerals. Iron pyrites ( FeS 2) is a sulphide mineral and siderite ( FeCO 3) is carbonate mineral.
