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). In the present work monosize experiments have been carried out using grinding rolls with controlled pressure.
High Pressure Grinding Rolls – Crushing and grinding for ore and minerals processing Introduction High Pressure Grinding Rolls (HPGR) were introduced as a new grinding technology in 1984. Since then, they have been successfully installed in a large number of plants throughout the world, mainly for cement and limestone. More recently, HPGRs have
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.
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.

The Cold Equation of State of Tantalum cold pressure tantalum. Abstract In highpressure isentropic compression experiments (ICE), the pressure is dominated by the cold curve. In order to obtain an accurate semiempirical cold curve for Ta, we calculate the thermal pressure from ab initio phonon and electronic excitation spectra.
