Mogensen's optical sorting technology can be applied to any bulk materials that can be clearly classified based on their color, transparency, shape, or size. In fact, it guarantees that materials that are difficult to sort and have an extremely wide range of compositions can be efficiently and effectively sorted with a high degree of accuracy.

Minerals, Rocks & Rock Forming Processes

Felsic Minerals: Felsic is a term used for silicate minerals, magmas, and rocks which have a lower percentage of the heavier elements, and are correspondingly enriched in the lighter elements, such as silica and oxygen, aluminum, and potassium. The term is a combination of FEL (for feldspar; in this case the potassium-rich variety) and SIC ...

Hydraulic sorting and mineral fertility bias in detrital ...

1. Introduction. Detrital geochronology is increasingly employed in paleotectonic reconstructions and landscape evolution problems. Detrital studies require a careful evaluation of the effects induced by hydraulic sorting, and by the variable propensity of different parent rocks to yield detrital grains of specific minerals when exposed to erosion (mineral fertility - Moecher and Samson, 2006).
