Kyanite, Andalusite, Sillimanite, and Mullite - Minerals ...

Description. IMAR 7 th Edition. Kyanite, andalusite, and sillimanite are naturally occurring anhydrous aluminum silicate minerals. Each has the same chemical formula, Al 2 SiO 5, but differing crystal structures, making them mineral polymorphs.These variances in crystal structure give somewhat unique physical properties to each of the three minerals, and each is used in slightly different ways ...

Kyanite and Sillimanite Beneficiation Process

May 26, 2016  Kyanite and Sillimanite Reagent Combinations. Sulphonated-petroleum collectors with alcohol frother and with sulphuric acid to a pH of 3.0 are the most common reagents for flotation of kyanite after conditioning. If sulphides occur in the ore they may be removed by regular xanthate flotation before de-sliming.

The name kyanite comes from the greek Kyanos which means deep blue. But this mineral has undergone a varied and rich naming process. At one point, Kyanite was named Disthen, meaning two strengths. This is because of the unusual property of having 2 different hardness measurements depending on which axis of the crystal is tested!

Kyanite and sillimanite are two polymorphic minerals with the same formula of Al2SiO5, but different crystal structures. Despite their high economic values, selectively recovering them by flotation is a challenge. In this study, the flotation behaviors of the two minerals with sodium oleate as the collector were examined at different pH conditions.
