Production Method

Natural Barite is produced through mining, crushing, beneficiation and grinding. Depending on ore characteristics, beneficiation may include washing, jigging, gravity separation, flotation, magnetic separation or other concentration methods to increase density and reduce unwanted gangue minerals. The processed material is then ground and classified according to the particle-size and application requirements.

Drilling Grade

For oil and gas drilling, Barite is primarily valued for its high specific gravity, which increases drilling-fluid density and helps control formation pressure. API Specification 13A defines Barite 4.1 and Barite 4.2 density grades and specifies additional physical and chemical requirements for drilling-fluid applications.

Storage & Shelf Life

Barite is a stable mineral product and should generally be stored in a dry area, protected from excessive moisture and contamination. Packaging should remain intact during storage and transportation. Shelf life is generally long when the product is kept dry and properly packaged; specific shelf-life information should be confirmed according to the supplier’s product specification.

Handling, Transportation & Shipment

Transportation & Dangerous Goods

Barite / Barium Sulfate is generally not classified as dangerous goods for standard road, sea or air transportation and does not normally have an assigned UN transport number. The applicable SDS should nevertheless be checked for the exact product specification and any impurities present.

Packaging & Shipment

Barite can be supplied in 25 kg bags, 50 kg bags, jumbo bags/FIBCs and bulk formats, depending on grade, quantity and destination. For drilling-grade material, packaging should protect the powder from moisture and contamination during international transportation.

Buyer Information

For drilling-grade Barite, buyers should confirm specific gravity, BaSO₄ content, particle-size distribution, API 13A compliance, packaging, quantity and required COA/SDS documentation before order confirmation. For non-drilling applications, the required BaSO₄ purity, brightness, particle size and other application-specific parameters should be established separately.
