SillimaniteWikipedia
Occurrence. Sillimanite is one of three aluminosilicate polymorphs the other two being andalusite and kyanite.A common variety of sillimanite is known as fibrolite so named because the mineral appears like a bunch of fibres twisted together when viewed in thin section or even by the naked eye. Both the fibrous and traditional forms of sillimanite are common in metamorphosed sedimentary rocks.

Chat OnlineGold extractionWikipedia
A "refractory" gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. These refractory ores require pre-treatment in order for cyanidation to be effective in recovery of the gold.
