cassiterite
tinstone

It is found as cassiterite in the mineral form.

But the average tin concentration level in cassiterite here is 60 percent - among the world's highest.

The land is rich in minerals such as gold, niobium and cassiterite.

Tin is made by heating cassiterite with carbon in a furnace.

Cassiterite and magnetite were found with the gold in the concentrates.

Bolivia's mines had produced cassiterite, the chief source of tin, since 1861.

The particle size of the cassiterite developed is also dependent on the temperature, and smaller than that used in the very beginning.

"By the end of the morning, we had washed 2,000 kilos of cassiterite."

In the 1940s interest surged again with the discovery of cassiterite mineralisation.

Cassiterite is also used as a gemstone and collector specimens when quality crystals are found.

This village had a nearby tin mine where, in addition to cassiterite, black tourmaline was found.

The subsoil is rich in minerals like cassiterite, nickel, and chromium.

These can commonly carry high levels of resistate minerals including cassiterite.

The state has many mineral deposits - especially gold, diamonds, cassiterite, bauxite and copper.

The deposit averaged 11 pounds of cassiterite per cubic meter of earth.

Early tin exploitation appears to have been centered on placer deposits of cassiterite.

It occurs as replacement of cassiterite in hydrothermal deposits.

This released cassiterite which was then smelted in local 'burning houses'.

The film maker knew it was cassiterite, tin mining, not coltan.

Cassiterite is a widespread minor constituent of igneous rocks.

Cassiterite is the principal ore of tin.

The ground around the deposit was littered with chunks of cassiterite weighing as much as 275 pounds.

In particular, it focuses on the cassiterite mine in Bisie.

Disdainful of controls, miners smuggled cassiterite by truck or airplane to Bolivia.

Bisie was established following the discovery of cassiterite by a hunter, and led to a frenzy.
