Research Status and Progress of the Exploitation and Utilization of Paigeite Ore

In this paper,the status and progress of the exploitation and utilization of domestic paigeite resource were analyzed,and the research progress in physical separation processes,hydrometallurgy separation processes and thermometallurgy separation processes were summarized.Such treatment methods as classification,gravity concentration,magnetic separation and flotation were mainly adopted in physical process.Alkaline method(carbon alkaline method) and acid method(one-step method) in hydrometallurgy separation process and blast furnace process and direct reduction-melting separation method in thermometallurgy separation process.The composition of paigeite ore was complicated,mainly containing szaibelyite,magnetite,ludwigite,uranatemnite and serpentine,which were difficult to be separated and utilized effectively by common mineral processing processes.Meanwhile,conventional boron extraction process was not suitable for paigeite,whichbelongs to an inferior iron or boron ore and cannot be exploited on a large scale.Therefore,it has great realistic economic and important strategic significance to carry on the research on new technologies and basic theories for the exploitation and utilization of paigeite ore.
