The chemical composition of specular hematite from Tilkerode, Harz, Germany: implications for the genesis of hydrothermal hematite and comparison with the Quadrilátero Ferrífero of Minas Gerais, Brazil | SpringerLink Home Mineralium Deposita Article Article Published: 12 March 2013
Metallic hematite, also called specular hematite, has a shiny luster and may exhibit a micaceous habit, which means that it is easy to break small flakes off a sample. The flakes are quite hard, but are easily separated from the sample, making it difficult to recognize the mineral's hardness.
The specular hematite ore sample used in this work was taken from the magnetic separation feedings in JISCO Company (China) and the iron grade was 26.65%. The chemical composition, mineral composition and XRD spectrum of this ore sample are shown in Table 1, Table 2 and Fig. 1, respectively.

Hematite physically occurs in many forms: specular ore (steel gray color, shiny crystals); micaceous hematite (gray, scaly flakes), Red ocher (soft, fine-grain, red powder); kidney ore (massive, gray botryoidal form), and pencil ore (gray, fibrous crystals). Because hematite has a high Iron content (70%), it is primarily used for smelting iron.
The BHQ ore was assayed as 38.9wt% Fe, 42.5wt% SiO2, and 1.0wt% Al2O3. In this ore, hematite and quartz are present as the major mineral phases where goethite, martite, and magnetite are present …

The mineral occurs in various habits: steel-gray crystals and coarse-grained varieties with a brilliant metallic luster are known as specular hematite; thin, scaly forms make up micaceous hematite; and crystals in petal-like arrangements are called iron roses. It also occurs as short, black, rhombohedral crystals and may have an iridescent tarnish.
