Kyanite. Kyanite is a blue silicate mineral which forms under high temperature, high pressure conditions. It is resistant to heat up to 1100 degrees Celcius, and is thermoelectric, making it a valuable component of thermal power plants. Assessment: Essential for advanced fabrication. Source: Scan Kyanite.

Grinding and Sizing. Kyanite is available in granular and powder forms and can be shipped in a variety of grain sizes, ranging from 35 mesh (425 microns) material to our micronized material (d50=10-16 microns). While 35 mesh is our standard, we also grind 48 mesh, 100 mesh, 200 mesh, 325 mesh, and other mesh sizes using specialized ball …

Sand. Quartz sand is our biggest byproduct. Our deposits in Central VA are comprised mostly of quartz. This must be removed to produce kyanite. Due to the purification process, our sand and kyanite are the same size. We produce substantially more sand than we do kyanite each year. Most of the sand is used for reclamation …

It helps clear bitter memories of the past, and helps to look at the present and the future in a new light. Kyanite promotes logic and rational thinking, especially in those people who are very impulsive and tend to make rash decisions.

Before gravity beneficiation, the raw ore needs to be ground. This process is completed in a ball mill. When the grinding fineness of kyanite reaches -0.15 mm with 47% passing, the spiral chute achieves the best separation effect. At this point, the kyanite grade can be increased to 18.47%, with a recovery rate of 95.20%.

Kyanite comes from the ancient Greek kyanos or kuanos, which means "deep blue.". As you know, kyanite comes in other colors, but you'll most commonly find the stone in blue. In a general sense, kyanite meaning relates to harmony and connection. Kyanite's spiritual nickname is the "Gemstone of Attunement.".
