Lead-gray metallic needle-like crystalline aggregate with guaranteed Sb grade and low penalty impurities.
Antimony Ore Stibnite Lumps
Guaranteed 63-65% Sb Content | Natural Stibnite Lumps | Ultra-Low Impurities | SGS/AHK Certified
ELMAGD MINERALS proudly supplies premium-grade natural Antimony Ore (Stibnite Lumps) extracted from selective high-grade mineral veins. Our ore features a certified antimony content of 63.00% to 65.50% Sb, characterized by a distinct crystalline needle structure, exceptionally high density, and ultra-low levels of penalty elements (Arsenic < 0.15%, Lead < 0.20%). Carefully hand-sorted and mechanically calibrated into 10–100 mm lumps, each lot undergoes rigorous third-party inspection (SGS / Alfred H Knight) prior to export in moisture-proof jumbo bags.
Laboratory Chemical Assay & Penalty Tolerances
| Element / Compound | Certified Assay Range | Commercial Benchmark / Rejection | Status |
|---|---|---|---|
| Antimony Content (Sb) | 63.00% – 65.50% | Guaranteed ≥ 63.0% | Guaranteed |
| Sulfur (S) | 24.50% – 26.20% | Stoichiometric Sb₂S₃ Balance | Guaranteed |
| Arsenic (As) | ≤ 0.15% (Typical 0.06 - 0.10%) | Rejection > 0.25% | Guaranteed |
| Lead (Pb) | ≤ 0.20% (Typical 0.08 - 0.14%) | Rejection > 0.35% | Guaranteed |
| Bismuth (Bi) | ≤ 0.05% | Trace / Ultra Low | Guaranteed |
| Selenium (Se) | ≤ 0.005% | Trace | Guaranteed |
| Mercury (Hg) | ≤ 10 ppm (0.001%) | Environmentally Compliant | Guaranteed |
| Moisture Content (H₂O) | ≤ 1.0% Max | Dry, Free-flowing Lumps | Guaranteed |
Penalty & Rejection Terms:
Assay is guaranteed between 63.00% and 65.50% Sb. In case the independent third-party certificate at loading port reflects an antimony grade below 63.00%, a pro-rata unit deduction applies down to 60.00% Sb. Rejection rights apply if Sb is below 60.00% or if Arsenic (As) exceeds 0.25%.
Mineral Physics & Crystal Structure
Screened Lump Sizes for Smelters
* All lumps are mechanically screened and dedusted prior to packing to keep fines (<10mm) under 8% maximum, ensuring optimal air permeability inside smelter blast furnaces.

Have Low-Grade Antimony Ore?
Antimony Ore Flotation Plant (EPC Turnkey)
In addition to exporting direct shipping high-grade stibnite lumps (63-65% Sb), ELMAGD MINERALS designs, engineers, and manufactures complete Turnkey Antimony Ore Flotation Plants. We upgrade lower-grade run-of-mine ores (1.5% to 15% Sb) into exportable 55%–65% Sb concentrates with recovery rates exceeding 88–94%.
Froth flotation circuit upgrading low-grade stibnite to 55–65% Sb concentrate.
