Tantalite Ore – Drayton Minerals

Tantalum is an important component in many modern technologies, and is used in capacitors for everything from computers to mobile phones. Despite its importance in the world today, tantalum mining takes place in very few countries. Only four countries produced tantalum in 2016, and most was mined in the Democratic Republic of Congo (DRC) Africa.

TANTALITE (Iron Manganese Tantalum Niobium Oxide)

Tantalite is the most widespread tantalum mineral and makes for an important ore of the industrially useful metal. Tantalum is used in alloys for strength and higher melting points, in glass to increase the index of refraction, and in surgical steel, as it is non-reactive and non-irritating to body tissues. Tantalite forms a series with the mineral columbite. In fact the two are often grouped ...

01/12/2020  The density of a coltan bearing ore is dictated by the tantalum grade and is generally between 5.3 and 7.8 g/cm 3 (Mirji et al., 2016). However, when the tantalum content is low, other minerals being present, such as cassiterite and wolframite could possess densities close to that of colombo-tantalite.

The beneficiation of tantalite ores usually involves pre- concentration, primary concentration and concentrate clean up. The choice of any or all of these processes would depend on the nature of the ore, particularly the content of Ta2O5 in the ore relative to its associated minerals and impurities. Typically, mechanically mined ores contain less than 0.1%Ta2O5, and would therefore essentially ...
