The production of ferroniobium at the Niobec mine

2019-12-2  The process used at Niobec was developed from the pilot plant programs and later modified by the mill personnel. A simplified flowsheet of this process is shown on Figure 1. Briefly, run of mine ore is crushed to minus 5/8"and fed to a rod mill, ball mill, and classification circuit where the ore is ground to 65#. The ore is deslimed in two stages of cycloning, and underflow is conditioned prior to flotation of a carbonate-apatite concentrate. This concentrate is cleaned twice and then pumped to tails. The carbonate flotation rougher and cleaner tails are cycloned in two stages to change the process water and then sent to the pyrochlore rougher flotation. The rougher concentrate is cleaned five times. This is followed by pyrite flotation to remove sulfur, leaching with hydrochloric acid to remove phosphorus and dried to less than 0.1% moisture before being sent to packaging prior been converted into ferroniobium.
