Limonite has the non-metallic dull luster. Hence, the correct option for limonite is C. Gypsum is a non-metallic mineral has the multiple lustres such as vitreous and silky. Hence, the correct options are B and D. Talc is the non-metallic mineral, which has the non-metallic pearly or dull luster.Limonite (/ ˈ l aɪ. m ə ˌ n aɪ t /) is an iron ore consisting of a mixture of hydrated iron(III) oxide-hydroxides in varying composition. The generic formula is frequently written as FeO(OH)· n H 2 O, although this is not entirely accurate as the ratio of oxide to hydroxide can vary quite widely. Limonite is one of the three principal iron ores, the others being hematite and magnetite ...

Metallic and Non-Metallic Minerals. ... Limonite, also known as the hydrated iron-ore, is yellowish in colour. It is an inferior iron ore containing 35 to 60 per cent of metal. Siderite is also called iron carbonate, in which iron content varies between 10 to 40 per cent.Limonite is commonly deposited in run-off streams resulting from mining operations. It also occurs in lateritic soils, and forms as pseudomorphs over minerals, such as siderite, marcasite, and pyrite. ... A nonmetallic mineral is not as reflective as a metallic mineral, but they can still be shiny. Some examples of nonmetallic minerals are talc ...
