Abstract
It was established, by electron probe microanalysis and petrographic e xamination, that phosphorus is present in rough pyrochlore concentrate s in the form of apatite represented by individual grains and intergro wths in niobium-containing minerals pyrochlore and columbite. Thin dis seminations of apatite in ferruginous niobium minerals is the main cau se of incomplete magnetic separation of niobium concentrates, even in high magnetic fields.
