The typical tantalum ore grade is in the range of 0.1–0.03% at the moment. The slag from cassiterite tin ore smelting contains up to 10–20% Ta 2 O 5, corresponding to 2.5–3% tantalum in the original ore. Tantalum has declined from ore grades of 1–0.4% in the period 1920–1930. In the 1980s, many mines were still in the range of 0.5–0.2%.
