The flotation behavior of ilmenite at different pHs was studied. As shown in Fig. 2, when BHA was used as a collector in the absence of an Al 3+ activator, the recovery of ilmenite flotation increased and then decreased as the pH of the pulp changed from 3 to 11. The floatability of ilmenite in neutral and weak alkaline environments was higher than that in strong acid or strong alkaline ...

Ilmenite is an economically important and interesting mineral. It is named for its place of discovery (such places are called type localities) at Ilmen Lake in the Ilmen Mountains, Miask in the southern portion of the Ural Mountains of Russia.

Ilmenite is an iron titanium oxide. It is the principal ore of titanium. It is black (or dark gray) and has a metallic luster. It is usually weakly magnetic. The mineral itself is actually not magnetic, but it is often intergrown with magnetite, which very strongly responds to the magnetic force. You can use a hand-held magnet to test sand grains.
