Co-processing refers to the simultaneous conversion of biogenic residues and intermediate petroleum distillates in existing petroleum refineries for the production of renewable hydrocarbon fuels. In contrast to the now common blending of biofuels into the finished petroleum product, co-processing makes use of biomass within the processing of petroleum.
Processing: extraction and refining.

It is most commonly found as pyrochlore - (Na,Ca)2Nb2O6 (OH,F) and most of the niobium mined is sold as ferroniobium, an alloy of niobium and iron. Over 90% of Nb is used in steels. Its principal use is as a grain refiner, where very small additions (200-1,000 g/t), significantly increases both steel strength and toughness simultaneously.

21-03-2020· In contrast with tungsten, niobium has a import reliance and a 0% EoL-RIR: in other words, Europe really depends on primary sourcing, namely from Brazil, for its niobium supply. The key supply chain stage which is responsible for niobium's high criticality is the processing step and, in particular, the refining of ferroniobium.
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 ...
