Baryte - Wikipedia

Baryte, barite or barytes (UK: / ˈ b ær ʌ ɪ t /, / ˈ b ɛər aɪ t / [citation needed]) is a mineral consisting of barium sulfate (Ba S O 4). Baryte is generally white or colorless, and is the main source of the element barium.The baryte group consists of baryte, celestine (strontium sulfate), anglesite (lead sulfate), and anhydrite (calcium sulfate). Baryte and celestine form a solid ...

Dissolution of Barite Scale Using Chelating Agents

(Chilingar, Mourhatch and Al-Qahtani 2008). Barite scales are typically grayish in color. Though pure barite is white, the scales may have impurities or organic materials trapped in them giving them a blackish tinge. Specific gravity of barite is around 4.5. The scales are fairly hard with Mohr hardness in the range 2.5-3.5.

Abstract The data in literature clearly proved that the polyamino carboxylic acids (PACAs) are promising barite dissolvers. So far, however, only the ethylene-diamin-tetraacetic acid (EDTA) and the diethylene-triamin-pentaacetic acid (DTPA) were studied and tested in detail. Therefore, an extensive research programme was launched to compare the potential of other barite dissolvers.
