An investigation on flotation process of low-grade
Froth flotation process has proved to be superior over other concentration methods when treating pyrochlore ((Na,Ca) 2 Nb 2 O 6 (OH,F) ores. This has led to use of reverse gangue flotation prior to pyrochlore flotation in cases were the ore contains high content of carbonate minerals [1]. Fatty acids are used as primary collectors. In cases where the ore does not

Coltan Earth Sciences Museum University of Waterloo
Coltan is mined by hand in the Congo. Their methods are very similar to how gold was mined in California during the 1800s. Groups of men dig basins in streams by scraping off the surface mud to get the Coltan below. Then they “sloth” the water around in large tubs, allowing the Coltan ore to settle to the bottom due to its heavy weight.

Coltan - Wikipedia
Coltan (short for columbite–tantalites and known industrially as tantalite) is a dull black metallic ore from which the elements niobium and tantalum are extracted. The niobium-dominant mineral in coltan is columbite (after niobium's original American name columbium), and the tantalum-dominant mineral is the tantalite.. Tantalum from coltan is used to manufacture tantalum
