AV ENTERPRISES

Appearance	Dark grey, brown, reddish-brown, or black, often with metallic luster.
Density	4.5 - 5.5 g/cm³ (varies depending on the type of iron ore).
Hardness	5.0 - 6.5 on the Mohs scale.
Specific Gravity	4.5 - 5.3 (varies depending on iron content).
Particle Size	Can vary from fine powder to large lumps, typically classified as fines (<6mm), pellets (6-16mm), and lumps (>16mm).
Porosity	1-5% (varies based on ore type and formation conditions).
Magnetic Properties	Magnetic (e.g., Magnetite) to non-magnetic (e.g., Hematite).
Moisture Content	Typically ranges from 1-10%, depending on mining and processing conditions.
	2.2 - 2.8 tonnes/m³ for hematite ores; 2.0 - 2.5 tonnes/m³ for magnetite ores.
Color	Grey, reddish-brown, or black, depending on iron content and type (e.g., Hematite is red; Magnetite is black).
Fracture	Irregular, uneven, or sub-conchoidal.
Tenacity	Brittle.
Grain Size	Can be fine to coarse, depending on the type and formation process.
Surface Texture	Can be rough, smooth, or pitted, influenced by weathering and processing methods.
Ore Types	Hematite (Fe₂O₃), Magnetite (Fe₃O₄), Goethite (FeO(OH)), and Limonite (FeO(OH)·nH₂O).
