The body uses zinc to process food and nutrients. When animals do not have enough zinc in their systems, they need to consume 50% more food to match the weight gain of an animal with enough zinc in its body. About 0.003% zinc is needed for proper health. Zinc is relatively non-reactive in air or water. Consequently, it is applied in …

Tantalum ore is composed of both tantalum and non-tantalum containing minerals, and the Ta 2 O 5-equivalent content is typically 0.02–0.04 percent. Low-grade tantalum ore is physically concentrated (beneficiation) to a concentrate of 20–40 percent Ta 2 O 5 -equivalent at the mining site before sale to smelters ( Linnen et al., 2014 ).

Lithium is an element valuable for the production of glass, aluminum products, and batteries. It is mined from ores of petalite (LiAl (Si2O5)2, lepidolite K (Li,Al)3 (Al,Si,Rb)4O10 (F,OH)2, spodumene LiAl (SiO3)2 and also subsurface brines. Australia and Chile are the world's largest producers of lithium.

Zone refining is a highly technological method for ultra-purification of metals. The principle of zone refining is that the impurities in an ingot of metal are more soluble in the melt state than they are in the corresponding solid state. In the zone refining process, the impurities are concentrated at one end of the ingot of metal so that the ...

Niobium oxide (Nb 2 O 5) is generally the starting chemical for the production of other compounds, such as niobium chloride (NbCl 5 ), niobium carbide (NbC), or lithium niobate (LiNbO 3 ). Niobium metal is produced by the aluminothermic reduction of the oxide followed by electron beam refining. Niobium powders can be produced by the reduction ...
