CRITICAL WARNINGS:
Refractory Application: Used as tap hole filler, EBT sand, and refractory material in the steel industry. Resistant to high temperatures.
Chemical Composition: MgO (47-50%) and Fe₂O₃ (7-9%) content determine olivine's refractory properties. High MgO content provides basic character.
Particle Size: Available in grain sizes ranging from 0-1 mm to 4-8 mm depending on application.
Surface Weathering: Although abundant underground, olivine weathers rapidly on the surface. Must be protected from moisture during storage.
Carbon Capture: Olivine reacts with CO₂ to form magnesium carbonate. This property is being researched for natural carbon capture and storage applications.
Dust Control: Silica and magnesium oxide dust inhalation may cause respiratory tract irritation. Appropriate dust control measures should be taken.
