Ilmenite Sand
High-density heavy mineral sand with optimal titanium content for welding flux coatings, blast cleaning, titanium slag, and high-density concrete aggregates.
Product Overview: Natural Ilmenite Sand
Ilmenite Sand is a naturally occurring heavy mineral sand composed of iron titanium oxide (FeTiO3). It serves as the primary global source for titanium dioxide (TiO2) pigment production and titanium metal extraction.
Sakthima supplies washed and electrostatically separated natural ilmenite sand with TiO2 content (TiO2 ≥ 50–55%), high specific gravity (4.5–4.8 g/cm³), and controlled grain sizing, ideal for welding electrode fluxes, blast cleaning, heavy concrete, and titanium feedstock.
Key Benefits
Arc Stabilization in Welding
Essential flux ingredient in shielded metal arc welding (SMAW) electrodes, improving slag detachment and bead appearance.
Heavy Aggregate Weighting
Provides high bulk density in undersea pipeline concrete ballasting and nuclear radiation shielding.
Non-silica Blast Abrasive
Environmentally safe blasting medium that eliminates free silica hazards while rapidly removing rust and mill scale.
Titanium Dioxide Feedstock
Readily digestible in sulphuric acid for sulphate process TiO2 pigment synthesis.
Blast Furnace Hearth Protection
Added to blast furnace charges to form a protective titanium carbonitride layer on hearth refractory linings.
Applications
Welding Electrode Flux Coating
Titanium Pigment Feedstock
Subsea Pipeline Weight Coating
Sand Blasting & Surface Prep
