Abstract

Abstract

China's tantalum and niobium ore is characterized by low grade, fine disseminated particle size, complex mineral composition, etc. It is necessary to select heavy separation, magnetic separationandflotation units to form a joint separating process for comprehensive utilization.Using the method of comparative analysis, the process mineralogical factors affecting the separating behavior of granite-type and granitic pegmatite-type tantalum-niobium ores were analyzed using Jiangxi Songshugang granite-type tantalum-niobium ore, Fujian Nanping granitic pegmatite-type tantalum-niobium ore, and Sichuan Jiajika pegmatite-type lithium polymetallic ore in which tantalum-niobium is an associated element. The analysis results show that: in granitic and granitic pegmatitic tantalum-niobium ores gravity concentration process, the state of occurrence of the tantalum-niobium elements has little influence on the separation behaviour of tantalum-niobium ores; The embedded characteristics of tantalum-niobium minerals are the main factors influencing the separation behaviour and index of tantalum-niobium ores; The sulphideminerals and strong magnetic mineral content of the ore is an important factor in the design of the tantalum-niobium ore cleaning process; When tantalum-niobium is an associated element, differences in embedded characteristics between the tantalum-niobium minerals and the main minerals can reduce the tantalum-niobium concentrate product specification.
