Emission factor summary
The activity generating the emissions is niobium mine operation and beneficiation, from pyrochlore ore. The Reference Product is pyrochlore concentrate. Pyrochlore concentrate (63% Nb2O5) is an intermediate product occurring during the processing of the pyrochlore (Na,Ca)2Nb2O6(OH,F), which is mineral group of niobium. The pyrochlore ore is mined, beneficiated and the undergoes carbothermic reduction to produce a refined pyrochlore concentrate. This concentrate serves as input for the aluminothermic reduction that produces Ferroniobium (66% Nb) the most principal product of the niobium production chain. The Reference Product amount is 1. The cut-off classification is allocatable product. The activity type is ordinary transforming activity.
