The mineral group tantalite is the primary source of the chemical element tantalum, a corrosion resistant metal. It is chemically similar to columbite, and the two are often grouped together as a semi-singular mineral called coltan or "columbite-tantalite" in many mineral guides. However, tantalite has a much greater specific gravity than columbite . Iron-rich …Web

Tantalite is the tantalum-rich member, and Columbite is the niobium-rich member. Tantalite is named after its tantalum content, and, together with Columbite, are the most important minerals containing the rare element tantalum. The name Tantalite has been discredited by the IMA, with the more specific designations of Tantalite- (Fe) (also known ...Web
Columbite ore is regarded as the most important primary source of Nb and/or sometimes Ta . It is often time referred to as tantalite [(Fe,Mn)(Ta,Nb) 2 O 6 ] when Ta 2 O 5 content in the mineral ore is significantly greater than Nb 2 O 5 [ 4 ]; and at times, referred to as columbite-tantalite (coltan) when it has almost equal percentage content ...Web

The primary ore of tantalum is the columbite-tantalite group. The columbite group is a solid solution with varying proportions of Nb or Ta in its composition. According to the International Mineralogical Association (IMA), 'tantalite' or 'coltan' are not scientific names, yet they are widely used.Web
The focus here is the archaeology, history and ethnography of indigenous, artisanal, small-scale mining, primarily in southern Africa. To begin the discussion, I outline a somewhat alternative history of mining in southern Africa and highlight what amounts to a distinctive ontology of the underground world and the processing of ore to metals.Web

Processing and separation of the tantalite would be done in any of the processing plant stated in the body of the report. The business would entail using mechanized method of mining to produce 300 tons bi-monthly of 1% tantalite ore in which minimum of 3 tons of 60% tantalite ore would be extracted.Web
The results in Figures 2 and 3 also show that the tantalite ore is concentrated within a depth interval of 2 to 45 m, and the mineralised vein is oriented in the NE-SW direction (Figure 2). A comparison of the tomograms from the nine profiles shows that the tantalite-rich quartz veins and pegmatites have varying lengths and thicknesses.Web
Columbite, also called niobite, niobite-tantalite and columbate, is a black mineral group that is an ore of niobium and tantalum. It has a submetallic luster and a high density and is a niobate of iron and manganese, containing tantalate of iron. Columbite and tantalite are collectively known as coltan in Africa.Web
