braunite การใช้

• Typical associated minerals include hausmannite, galaxite, braunite, pyrolusite, coronadite, hematite and magnetite.
• It occurs in low-grade metamorphosed sedimentary manganese ore deposits associated with hyalophane, braunite and tamaite.
• It occurs in association with pyrolusite, nsutite, braunite, chalcophanite, manganite and various other manganese oxides.
• Botnedalen is known for the occurrence of various minerals, including hausmannite, jacobsite, braunite, bustamite and rhodonite.
• A calcium iron bearing variant, named braunite II ( formula : Ca ( Mn 3 +, Fe 3 + ) 14 SiO 24 ), was discovered and described in 1967 from Kalahari, Cape Province, South Africa.
• Zoning exists within the ore body both in the vertical and horizontal sense, where horizontal zoning is fault related and shows high grade Hausmannite ore, intermediate areas show a very complex mineral assemblage ( Including Braunite and Jacobsite ), while distal areas have a lower grade ore consisting predominantly of Braunite and Kutnohorite.
