ANTIMONY: A CRITICAL MINERAL OF STRATEGIC IMPORTANCE TO MODERN TECHNOLOGIES
Antimony
Antimony ​​​
Antimony is a silvery-white chemical element commonly found in mineral deposits Stibnite. The ore is typically processed to produce Antimony, which plays a crucial role as an essential raw material for many industries. It is valued for its unique properties to act as a flame retardant in textiles and plastics. It is also used in the production of semiconductors and lead-acid batteries which are commonly found in vehicles and electronic devices. Even though Antimony is hard, it is easily broken and is widely used to make other metals harder and stronger.

Production Processes for Antimony Concentrates from Stibnite
​
​
The beneficiation of Antimony concentrates involves a series of well-defined stages, utilizing state-of-the-art techniques informed by geological survey data to extract maximum value from Stibnite ore.
​
Mining and Material Handling: Efficient mining practices are foundational to successful beneficiation. We employ selective mining techniques based on geological survey data to target high-grade Stibnite deposits, ensuring optimal resource utilization while minimizing waste. Safety protocols are strictly followed to protect our workforce and the environment.
​
Crushing and Grinding: The first stage in the physical separation of Antimony minerals involves crushing and grinding the ore to liberate Stibnite from gangue materials.
​
Flotation: Flotation is the primary method for separating Antimony minerals from other constituents. Our approach includes: Reagent Optimization & Air Flow Management. often using lead salts, copper salts, butyl xanthate, shale oil, ethyl thiazide, pine oil, or No. 2 oil as reagents.
​
Concentrate Thickening and Filtering: Post-flotation, the Antimony concentrates undergo thickening and filtering processes.
