ore concentrate which is then put through a metallurgical process. Hydrometallurgy, pyrometallurgy or a combina-tion of the two are used to “refine” the concentrate by de-taching the atoms of the target elements from the crystal lattice at the atomic level. These metallurgical techniques have much in common with thermal process engineering,

Pyro-metallurgical process- smelting reduction: -Mo and other metals are reduced and recycled as ferroalloys; -The non-reducible materials are left in the slag. -High processing capacity, but also high energy consumption. Hydro-metallurgical process: -Mo in the spent catalysts is converted into soluble compounds and leached out.
The neodymium fluoride was reduced to metal by thermal reduction or pyro-metallurgical process using calcium as reducing agent. Thermal reduction was carried out in a sealed reactions chamber in inert atmosphere with a nickel crucible having dry calcium fluoride lining.

Hydrometallurgy is a method for obtaining metals from their ores. It is a technique within the field of extractive metallurgy involving the use of aqueous chemistry for the recovery of metals from ores, concentrates, and recycled or residual materials.
The main results of LCA study are summarized as follows: (1) Hydro-metallurgical process is superior to pyro-metallurgical process in GWP and inferior to pyro-metallurgical process in GER and ACP. (2) Compared with the advanced foreign zinc metallurgical process, the GWP, ACP and HME of the zinc metallurgical process in China are much higher.
