Barite Beneficiation Solutions

Barite beneficiation solutions: a professional way to create high-quality products

I. Solution Overview: Precise sorting, empowering the maximization of resource value

Barite (BaSO₄) is a key non-metallic raw material indispensable to oil drilling, chemicals, paints and pharmaceuticals, etc. Its purity, whiteness and specific gravity directly determine the value of the product and the level of application. We provide customized barite beneficiation solutions based on our in-depth experience in mineral processing. The core of the solution covers three major process routes of re-election, magnetic separation and flotation, which can be flexibly combined and optimized according to the characteristics of the ore (grade, embedded particle size, impurity composition) and the requirements of the target products (petroleum-grade, chemical-grade, pharmaceutical-grade), and ultimately achieve high-quality concentrates with a BaSO₄ content of ≥ 92-98%, whiteness ≥ 90%, and specific gravity of ≥ 4.2, which will help our clients to We can help our customers to occupy the high-end market.

Core process: a combination of technologies tailored to the "mine".

1. Leading re-election process: the first choice for high efficiency and economy.

• Applicable conditions:

  • Barite in the ore is embedded in coarse grains (+0.5mm)

  • Raw ore grade BaSO₄ ≥ 30%.

• Process flow:

  • Crushing and screening: Jaw crusher + cone crusher is used for two-stage crushing, followed by circular vibrating screen for grading to prepare suitable particle size for sorting.

  • Jigging: The core sorting equipment is jigger, which can separately process different grain sizes (e.g. coarse and fine grains) and separate barite and veinstone efficiently by using gravity difference.

• Technical index: concentrate BaSO₄ content ≥ 85-92%, can be directly used as oil drilling mud weighting agent.

2. Magnetic separation and iron removal process: a powerful tool for purification and whitening

• Applicable conditions:

  • Ore containing ferromagnetic impurities (such as rhodochrosite, hematite, pyrite)

  • The target products are pharmaceutical grade, paint grade and other high whiteness and high purity requirements.

• Process Flow:

  • Adopt high gradient wet magnetic separator (background field strength 1.0 - 1.5 Tesla ) to conduct multi-stage magnetic separation for crushed ore or reelected rough concentrate.

• Iron removal effect: It can effectively reduce the Fe₂O₃ content in the concentrate to less than 0.5%, and significantly improve the whiteness and purity of the product.

3. Flotation purification process: overcome the difficulties of low grade and fine grains

• Applicable conditions:

  • Low-grade ore (BaSO₄ content 8-20% )

  • Barite is embedded with fine or micro-fine grains (-0.074mm).

  • High purity products (≥95%) such as chemical filler grade are required.

• Process Flow and Pharmacy:

  • The flotation process of "one coarse, three fine, two sweep" is the classic configuration to ensure the recovery and grade.

  • Pharmacy system: Adopt fatty acid (anionic recovery agent) or amine (cationic recovery agent) as the core recovery agent, and match with high efficient inhibitor and adjusting agent, to realize the high efficient separation of barite and fluorite, calcite, quartz and other vein stones.

• Technical index: concentrate BaSO₄ content ≥ 92-96%, recovery rate of more than 80%.

III. Recommended configuration of core equipment

Solution Core Advantages

• Excellent quality, suitable for high-end market:
  Through the combination of processes, it can stably produce various products to meet the requirements of petroleum grade (specific gravity ≥ 4.2), chemical grade (BaSO₄ ≥ 92%), pharmaceutical grade (BaSO₄ ≥ 95%, Fe₂O₃ ≤ 0.5%), with strong competitiveness.

• Flexible and economical, fast return on investment:

  • Modular design, processing scale from 50-1000 tons/day flexible optional, support phased construction.

  • The payback period of re-election process is often shorter than 1 year; flotation tailings can be considered for comprehensive utilization to create additional income.

  • Equipment selection focuses on reliability and energy saving, with low operating costs.

• Mature technology and global project validation:
  Our solutions have been successfully applied in many barite mines at home and abroad, with stable and reliable technical indicators and rich experience.

V. Successful Cases

Project Name: A low-grade barite tailings re-election project

• Nature of raw ore: BaSO₄ content of only 12%, fine particle size (-200 mesh accounted for 80%), is difficult to use resources.

• Solution: Adopt the flotation and purification process of " one coarse, three fine and two sweeps ", together with our unique pharmaceutical system.

• Final index:

  • Concentrate Grade: 96.5% BaSO₄

  • Recovery rate: 81

  • Annual processing capacity: 80,000 tons

• Project Benefits: Successfully transforming waste tailings into high-value products, with extremely significant economic and environmental benefits.
