1. Physical Specifications

These describe how the ore looks and behaves physically:

• Size / Lump distribution
  e.g., fines (<6 mm), lumps (6–40 mm)
• Moisture content
  Typically expressed as % (e.g., max 8–12%)
• Bulk density
  Important for transport and storage
• Hardness / friability
  Determines crushing and handling behavior
• Color & texture
  Useful for quick identification (e.g., reddish for iron ore)

2. Chemical Composition

This is the most critical part of the specification:

Example: Iron Ore Specification

• Fe (Iron content): 58–65% (higher is better)
• SiO₂ (Silica): <5–8%
• Al₂O₃ (Alumina): <3–5%
• P (Phosphorus): <0.1%
• S (Sulfur): <0.05%
• LOI (Loss on Ignition): Indicates moisture & volatile content

Example: Copper Ore

• Cu content: 0.5–2% (economic grade varies)
• Fe, S content
• Impurities: arsenic, lead, zinc

Example: Gold Ore

• Au grade: grams per tonne (g/t), e.g., 1–10 g/t
• Associated minerals: quartz, sulfides

---

3. Mineralogical Composition

• Types of minerals present (e.g., hematite, magnetite in iron ore)
• Grain size distribution
• Liberation characteristics (important for processing)

---

4. Metallurgical Properties

• Recoverability (how easily metal can be extracted)
• Beneficiation suitability (gravity, flotation, magnetic separation)
• Smelting behavior

---

5. Contaminants & Penalties

Certain elements reduce value or incur penalties:

• Arsenic (As)
• Mercury (Hg)
• Chlorine (Cl)
• Excess silica/alumina

---

6. Sampling & Testing Standards

• Sampling method (random, composite)
• Laboratory test methods (e.g., XRF, fire assay)
• Standards (ISO, ASTM)
