This study presented the first in a series of investigations currently underway to develop efficacious, cost-effective, and benign processing opportunities produce rare earth elements (REE)–rich concentrate from an Australian complex low–grade saprolite ore [1.14% total oxides (TREO) grade], which is primarily exploited for its gold copper values. work specifically preliminary flotation investi...

Exploring new ways to acquire niobium resources is essential resolve supply risks, due the fact that, at present, 99% of controlled by only two countries. In present work, a flotation technique was applied separate from low-grade niobite ore. To maximize utilization original ore resources, pre-flotation conducted recover sulfur and eliminate adverse effects sulfide on flotation. The obtained gr...
