Economic Geology of Niobium and Tantalum Walter Pohl
As columbite is initially free of lead and because of its resistance to later alterations, the mineral is useful for UPb dating of granites and pegmatites (Romer et al. 2007). Scandium in columbite and related minerals may reach >6 wt. % (Kempe & Wolf 2005). Scandium (density 3.0 g/cm 3, melting point 1539°C) is a typical dispersed element.
Froth flotation Wikipedia
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and wastewater treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
