Hydrometallurgical Process. Hydrometallurgical processes allow to obtain as final products base metals (Cu, Zn) and salts of critical metals like yttrium and europium oxalates with high purity that could be sent to the market or sold to companies for refining.

Thus, while all hydrometallurgical methods essentially have a low air pollution potential, some recently developed methods use chemistry which yields elemental sulfur directly from the sulfur minerals present in the ores, to give a cleaner process overall. Hydrometallurgical copper recovery can be conveniently considered in two stages: the leaching stage, in which the various forms of

We have considerable expertise in hydrometallurgical unit operations such as leaching,pound (LiMn1/3Co1/ 3Ni1/3PO4) results . marketing and global sales of lithium and tantalite mineral products.
This study focused on the leaching of uranium and thorium from a high grade Ethiopian tantalite ore using sulfuric acid. The effects of variables such as acid concentration, temperature and leaching time were studied. In general, the leaching efficiency of uranium increases with increasing temperature from 100 to 300 °C whereas the opposite trend was observed for thorium.

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, blue-gray, lustrous transition metal that is highly corrosion-resistant. It is part of the refractory metals group, which are widely used as minor components in alloys. The chemical inertness of tantalum
