Barite is a non-metallic mineral primarily composed of barium sulfate, often coexisting with sulfide ores (galena, sphalerite, chalcopyrite) and iron-bearing minerals. As a non-renewable resource, it is widely used as a weighting agent in oil/gas drilling mud, raw material for barium chemicals and fillers, and a contrast agent in medical digestive system examinations. To meet industrial quality standards (e.g., low iron content for medical use, high purity for drilling), a specialized barite beneficiation process is essential—integrating crushing, screening, gravity separation, magnetic separation, and flotation to separate impurities and upgrade grade. Our custom barite processing solution is tailored to ore properties, delivering high-grade concentrate that maximizes industrial value.
Core Beneficiation Processes of Barite Processing Solution
Barite ore requires targeted separation based on particle size and impurity type, with four key process stages:
Crushing & Screening:
Large mined barite is crushed by a jaw crusher (coarse crushing) and cone crusher (fine crushing) to suitable particle size.
A circular vibrating screen (high capacity, low failure rate) sorts crushed materials, ensuring qualified particles enter subsequent separation stages.
Gravity Separation (Jigging):
Jigging machines are the core equipment for barite gravity separation, handling both coarse and fine particles.
This process yields high-grade concentrate (purity ≥80%) with advantages of energy saving, high efficiency, and environmental friendliness.
It is the primary method for upgrading barite, leveraging density differences between barite and gangue minerals.
Magnetic Separation (Iron Removal):
Wet magnetic separators are used to remove iron-bearing minerals (e.g., siderite) from barite.
Critical for producing medical-grade barite (required for barium-based medicines with ultra-low iron content).
Flotation Separation:
Applied to finely disseminated barite ore and gravity separation tailings, where physical separation is ineffective.
Anionic collectors (fatty acid alkyl sulfates, alkyl sulfonates) or cationic amine collectors are selected based on adsorption mechanisms to float barite.
