These processes help to produce pure antimony (Ingot) that can be efficiently used in various industries.
1. Mining
Our mining is underground mining as we extract antimony ore deep beneath the surface.
2. Ore Beneficiation
After mining, the ore must go through the mineral dressing process to increase the antimony concentration.
- Crushing & Grinding reduce the size of the ore.
- Gravity Separation separates antimony from the waste rock.
- Flotation Process uses chemicals to separate antimony from other ores.
- Antimony concentrate contains approximately 20-60% of antimony.
3. Smelting
Smelting process converts antimony concentrate into antimony metal.
-
Reduction Smelting
- High temperature (~1000°C) smelting furnace
- Carbon (e.g. coke) is added to reduce antimony sulfide (Sb₂S₃) into antimony metal (Sb).
- Pure antimony ingot 99.65-99.90% Sb
-
Oxidizing Smelting
- Oxygen is used to combust antimony ore to produce antimony oxide (Sb₂O₃).
- Used in the chemical industry, such as in flame retardants.
4. Industrial Usage
Antimony metal is used in various industries such as
- Used as a flame retardant for the plastic, textile, rubber, paint and electronics industries.
- Used as an alloy to increase strength and abrasion resistance for the production of bullet heads, solder.
- Used as a catalyst for the production of PET plastics (beverage bottles, polyester fibers).
- Battery industry to increase strength and durability in battery production.
- Glass and ceramic industry to be an air-repellent and turbidity-repellent.
- Electronics industry to be an impurity and a component of semiconductors.
