Large cassiterite crystals from the Pelepah Kanan tin mine in central Johore differ from those at Aberfoyle and Renison Bell, Tasmania, in showing strong colour zoning and possessing a small but conspicuous magnetic fraction. By separating crystals from these localities into fractions of varying magnetic susceptibility, there is found to be a distinct relationship …

Processing: extraction and refining. The extraction and refining of tantalum, including the separation from niobium in these various tantalum-containing mineral concentrates, is generally accomplished by treating the ores with a mixture of hydrofluoric and sulfuric acids at elevated temperatures. This causes the tantalum and niobium values to ...

The process was implemented by the American corporation Potash & Chemical Co in the 1950s. Lepidolite is mixed with limestone (mass ratio of 3:1) and wet ball milled. The discharge is filtered and roasted in a kiln at 800 to 1000 °C. The roasted material is quenched, wet ground, leached in a counter-current mixer settler system and dewatered.

There will be two ways floatation for columbite-tantalite ore beneficiation. a. During floatation, alkyl sulfonated succinate will be used as collector, sodium silicate and oxalic acid as regulators to make PH of 2 to 3. For the concentrate from this floatation separation, shaking table-belt sluice can be used for further fine selection. b.

Tantalum shares many of its properties with niobium (Nb), with which it is commonly found. This close association has led to use of the 'coltan' terminology, short for columbite-tantalites, reflecting the niobium-dominant (columbite) 2 and tantalum-dominant (tantalite) end-members of this oxide mineral series (see text box below). Tantalite is ...
