Niobium and tantalum are transition metals that are almost always found together in nature because they have very similar physical and chemical properties. Their properties of hardness, conductivity, and resistance to corrosion largely determine their primary uses today. The leading use of niobium (about 75 percent) is in the production of high-strength steel alloys used in …

Gravity concentration is often used in roughing separation of tantalum-niobium ores. And in the concentrating of ores, we often adopt gravity concentration, flotation, electromagnetic separation or dressing-metallurgy combining process. Ore washer and efficient ore grinder and grader are also utilized to increase the fineness of ores.
Ways to invest in tantalum: Supply and demand. Tantalum is rare, averaging only 2 parts per million in the Earth's crust. There are few mines solely dedicated to production of the refractory metal ...
· Tantalum is produced as a byproduct of tin and niobium mining. Historical data show that the amount of tantalum produced during tin and niobium mining was much closer to the potential maximum than was the case with germanium. So the availability of tantalum is more of a concern for the possible scale-up of an LLZO-based battery.

MINING AND PROCESSING : Tantalum is produced by the processing and refining of its ore tantalite. Tantalite is the mineral ore containing tantalum. Most tantalum mines are open pit whereas some are underground. The mining process involves blasting, crushing and transporting the tantalite ore to start the process of separating tantalum.
Tantalum also enables important advances in chemical and pharmaceutical processing, aerospace, energy and ballistic applications. Tantalum Mining Corporation of Canada, or "TANCO," is located close to the Whiteshell Provincial Park, about 180 kilometers northeast of Winnipeg and is wholly owned by Cabot.
