Wolframite flotation is performed similarly to the above-described scheelite flotation, but is not pH sensitive and can therefore be undertake in both acidic and alkaline solutions. Generally, flotation is rarely applied to wolframite The reason is that wolframite occurs mainly in vein-type deposits whose mineralization is much coarser than to most scheelite ores. Therefore, gravity and magnetic methods are more desirable than flotation.
