How To Detect Coltan

Data Evaluation for Cassiterite and Coltan Fingerprinting

Two data evaluation approaches named "Kolmogorov–Smirnov distance (KS-D) approach" and "areas ratio approach" are applied to coltan and cassiterite and result in very low rates of false negative results, which is desired for AFP.

XRF Analysis of Ta-Nb (Coltan), Sn, and W

Locating and verifying viable sources of tantalum, niobium, and tin is a challenging task that requires advanced tools, such as handheld X-ray fluorescence (XRF) analyzers. Geologically, Ta, Nb, and Sn are found in late-stage magmatic formations, such as pegmatites and high-temperature veins.

XRF Analysis of Ta-Nb (Coltan), Sn, and W

Geologically, Ta, Nb, and Sn are found in late-stage magmatic formations, such as pegmatites and high-temperature veins. Minerals like tantalite ((FeMn)Ta2O6), columbite ((FeMn)Nb2O6), and cassiterite (SnO2) are common sources of these elements. Tantalite is frequently found alongside columbite, forming a mineral mi…
