hematite can have both metallic and nonmetallic luster.
Hematite is typically shiny when it is polished or cut, giving it a metallic luster. However, in its natural form, hematite can appear dull or metallic depending on the surface finish and impurities present.
Magnetite
Hematite is a metallic mineral. Remember, minerals make up rocks.
galena, pyrite, and hematite all happen to be distinct in their metallic luster.
The mineral that leaves a grey streak and is metallic is likely hematite. Hematite is a common iron oxide mineral that has a metallic luster and leaves a grey streak when scratched against a rough surface like unglazed porcelain.
Metallic minerals are those that contain metals, such as iron, copper, and gold, and have a shiny appearance. Non-metallic minerals do not contain metals and are used for various purposes, such as building materials (e.g. limestone and gypsum) and fertilizers (e.g. phosphate). Examples of metallic minerals include silver, zinc, and lead, while examples of non-metallic minerals include quartz, coal, and salt.
Hematite typically has a metallic luster, appearing shiny and reflective like polished metal.
Metallic minerals are minerals that have a metallic luster, making them very shiny. A few metallic minerals are Graphite, Galena, Magnetite, and Pyrite. The mineral Hematite can be metallic or nonmetallic
Hematite is the main component of Fe2O3, single crystal often has rhombohedral and plate, aggregates varied shapes. Metallic luster to the semi-metallic luster, hardness of 5.5 to 6.0, a density of 5.5 ~ 5.3 g · cm-3. Iron was black, shiny sheet metal aggregates called mirror hematite iron ore; gray, metallic flake mica, hematite aggregates called hematite; reddish brown, shiny dark ocher called ; was kidney-shaped hematite called kidney-shaped hematite. Hematite widely distributed in nature pole is an important raw material for iron, a red pigment may also be used.
Hematite typically appears as a metallic to dull silver-gray or black stone with a shiny metallic luster. It often exhibits a reddish-brown streak when it is scratched on a surface. It is commonly found in botryoidal (rounded masses resembling grapes) or reniform (kidney-shaped) formations.
