There are many uses of Tantalum metal and below are details on machining Tantalum including welding, grinding, spinning and more. Turning and Milling. In lathe operations, cemented carbide tools with high cutting speeds should be used. The tools should be kept sharp and ground with as much positive rake as the tool can withstand.
I have never machined Tantalum or Rhenium, but I did a turning job in TZM 364 which is a sintered alloy containing 99.4 molybdenum alloyed with Titanium and Zirconium. That shit was nasty. It did chip just like cast iron and made the same kind of noise you get when turning cast iron, but nastier grinding, rumbling.
Machining of tantalum is difficult. It has been described as kind of like machining copper with the hardness of titanium annealed tantalum may cause problems, being sticky, as well as having a strong tendency to seize, tear and gall tantalum material is in general more suitable for machining than annealed.
Title Machining Guide for Tungsten Alloys as per ASTM B 77707 Subject Guide to machining tungsten alloys as per ASTM B 77707 including, recommended tools and coolants, grinding, turning boring, drilling, tapping, milling, and roughing operations
Tantalum is a chemical element with the symbol Ta and atomic number 73. Previously known as tantalium, it is named after Tantalus, a villain from Greek mythology. Tantalum is a rare, hard, bluegray, lustrous transition metal that is highly corrosionresistant. It is part of the refractory metals group, which are widely used as minor components in alloys. The chemical inertness of tantalum

Cryogenic grinding of tantalum for use in capacitor manufacture or a carbon nitride from the group of metals consisting of ruthenium, cobalt, manganese, molybdenum, tungsten, tantalum, iron, niobium, iridium, titanium, zirconium, hafnium, rhodium, vanadium, osmium, palladium, platinum, nickel, lead, alloys, and mixtures thereof
articleosti4019822, title ELECTROLYTIC POLISHING OF REFRACTORY METALS, author Cortes, F R, abstractNote A versatile solution, composed of small amounts of sulfuric and hydrofluoric acids in methanol, is discussed for electropolishing molybdenum, tungsten, tantalum, and niobium. Grinding and polishing procedures are also described.
Available pure or as an alloy, tantalum contains hightemperature mechanical properties. With a highdensity composition, these materials provide extreme strength and toughness, as well as strong stiffness and excellent corrosion resistance against acids. The most common tantalum alloy is 90Ta10W, which contains 10 percent tungsten.

Tantalum is a strategic metal and an improvement of the mineral processing is an important issue. The main objective of this work is to optimize the grinding technologies for tantalum ores with high pressure grinding rolls. The selected ore for this study was an altered leucogranite from the Penouta Open Pit Mine NW Spain.
Tantalum is a critical metal that is widely used in electronic products. The wires are made of iron and nickel. Electrodes, including cathodes, anodes, and dielectrics, are made of tantalum powder and other elements. was used in the pretreatment process to determine the temperature for pyrolysis. Then, grinding and washing with water
The magnetic tantalum concentrates recovered from each of the three steps were combined into a final tantalum product. Only two flow sheets were evaluated using sample B. Preliminary grinding to 589 m followed by magnetic separation produced results nearly identical to those obtained when no preliminary grinding was used.
Tantalum niobium iron ore is mainly tantalum, niobium tin, tungsten, lithium, beryllium and other polymetallic ore. Has the characteristics of low grade and complex mineral composition
