tantalum and tin processing

Tantalum Processing TIC

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 ...

High Demand in Mining for Tantalum and Tin

2013-11-14  Tantalum is very hard, extremely corrosion resistant, easily fabricated, and is a good conductor of heat and electricity. Tin (Sn) is another highly corrosion-resistant element and is applied to other metals to prevent corrosion. Tin is used in the electronics industry in solders, and tin-plated metal is used to make cans for food packaging.

MINERAL PROCESSING AND RECOVERY OF TANTALUM

Concentrates of Golpejas and Penouta contain columbo tantalite. Up to 15% of the total tantalum and niobium content of these concentrates are present in the cassiterite as microinclusions and can not be recovered by the mineral processing. These elements are concentrated in the tin slag during the metallurgical processing of cassiterite.

Titanium Nitride - Enigmatics

2021-8-30  Titanium nitride is a hard, dense, refractory material with unusually high electrical conductivity. TiN is very hard and has a very high melting point, and it is a poor thermal expansion match to silicon; thus stress is often an issue if thick films are employed. TiN has unusual optical properties, including an attractive gold-tinged appearance ...

2021-2-24  A third benefit is that processing ore would help the local economy. In 2020, reported world imports of tantalum and niobium ores from the DRC had a total value of about US$80M. Had that material been converted before export to even a 99.5% Ta 2 O 5 product, its value would have been perhaps three times as much.
