wolframite

In 1860 a rich body of ore containing wolframite was discovered.

In natural occurrence the percent range fall within 20-80 percent of the wolframite series.

Hübenerite is a rare member of the wolframite group.

For example at 40 kilobars, it adopts a structure related to wolframite.

The wolframite is scattered extremely thinly throughout the granite.

Furthermore, the wolframite deposits discovered and mined in the municipal area are interesting.

Mn)O) is the usual structure of all member in the wolframite family.

Two ores which have tungsten in them are wolframite and scheelite.

Along with scheelite, the wolframite series are the most important tungsten ore minerals.

Hübnerite is a rare mineral from the rare family wolframite.

Short prismatic, flattened or wedge-shaped are the common crystals of the wolframite itself.

He first had the idea that wolframite might contain a previously undiscovered element (tungsten).

The second pair were strongly magnetised and attracted the wolframite, which is weakly magnetic.

Peter Woulfe was the first to recognize a new element in the naturally occurring mineral, wolframite.

The ore minerals of tungsten include wolframite, scheelite, and ferberite.

I want a ball of copper, I want a lump of wolframite.

Armed groups and the Congolese army control nearly all the trade in tin ore, gold, columbite-tantalite and wolframite.

Its important ores include wolframite and scheelite.

Some of the most important wolframite mines in the world (a mineral source for the element tungsten) are explored within its municipal limits.

Pharmacosiderite, Cassiterite and Wolframite of specimen quality have also been recovered from the mine.

Wolfram(Wolframite) deposits are found in renwat hill at degana.

In most cases wolframite is embedded in quartz as subparallel crystalline masses.

They need wolframite.

It is the manganese endmember of the manganese - iron wolframite solid solution series.

Thus, the ores, are treated with base to give sodium tungstate, as illustrated in the case of wolframite:
