Barite bụ isi, ndammana na-ewere ọnọdụ, barium dabeere ịnweta. Barium, ọnụọgụ nzùrùòkè 56, na-erite aha ya site na Grik na pụtara arọ. Barite na-mara dị baryte. The isi mba na nke azụmahịa ego nke barite na-ugbu a hụrụ bụ United States, China, India na Morocco. Barite elu njupụta na chemical inertness-eme ka ọ dị mma ịnweta maka ọtụtụ ngwa.
The chemical usoro maka barite bụ BaSO4. Ọ nwere nnukwu kpọmkwem nnukwu mpo nke 4.50 g / cm3. Ya Mohs ekweghị ekwe bụ 3.0 ka 3.5. Barite, nke a na-achọta na a dịgasị iche iche nke agba gụnyere odo, aja aja, ọcha, acha anụnụ anụnụ, isi awọ, ma ọ bụ ọbụna colorless, a nwere a vitreous ka pearly luster.
Barite nwere ike hụrụ na njikọ na ma dara na nonmetallic ịnweta ego. Iji-aku na uba viable maka mmịpụta, barite emekarị kwesịrị ịbụ ndị kpagburuibe ihe a nkwụnye ego.

Dry Barite Beneficiation
STET nwere ma pilot ọnụ ọgụgụ na azụmahịa ahụmahụ nhazi barite wepụ gangue dị ka silicates, ígwè, and alumina. Low-grade barite beneficiation with a specific gravity between 3.5 - 4.0 has been successfully upgraded using the STET process to product API-grade barite.
STET nwere ike na-egosi na akọrọ electrostatic nkewa usoro na-enye ọtụtụ uru n'elu omenala mmiri nhazi ụzọ (flotation) tinyere:
