Abstract Cassiterite is an n-type semiconductor whose properties may be altered by aliovalent doping. Such changes are noted in color, electrical conductivity, electrokinetic behavior and, as will be demonstrated in Parts II and III, by flotation behavior.

The Zero Point of Charge of Cassiterite
Bulletin des Sociétés Chimiques Belges, 1986AbstractThe zero point of charge (ZPC) of cassiterite was investigated by measuring the electrophoretic mobility, solution equilibrium, and flotation response as a function of solution pH. The ZPC was shown to lie at pH 2. The potential determining ions for cassiterite are H+ and OH−.The effect of anionic and cationic collectors on the zeta potential ...

Fractionation of Zr and Hf in cassiterite
Chemical Geology, 1983Abstract Analytical data on Zr and Hf in cassiterite samples from various genetic types of deposits are reported. Two genetic groups of cassiterites can be distinguished by their Zr/Hf ratios, which are ∼5 and ∼30 for samples from pegmatites and hydrothermal vein mineralizations, respectively.

Geochemistry of some Cornubian cassiterites
Mineralium Deposita, 1979Magnetic and non-magnetic cassiterite from St. Michael's Mount and Cligga Head, Cornwall, have been analysed by electron microprobe. Differences in their chemical composition are attributed mainly to the presence of inclusions of wolframite. The colour zoning in these cassiterites cannot be attributed to the presence of iron.

Morphology of polycrystalline cassiterite films
Crystallography Reports, 2014Polycrystalline cassiterite films have been grown by the hydropyrolytic method from a 10(H2O) + 5(SnCl2 · 2H2O) solution (in weight fractions) on corundum substrates. The crystallization regularities are considered and a comparative analysis of the properties of natural and artificial cassiterite crystals is performed.

Cassiterite of the Straits Settlements
Mineralogical Magazine and Journal of the Mineralogical Society, 1886The tin from the Straits Settlements has hitherto been solely derived from the alluvial deposits, and is consequently in the form of alluvial or "stream" tin—each grain of Cassiterite being separate, and in many cases so considerably water-worn as to afford evidence of its having been washed down for a considerable distance; the angles of the grains ...

Abstract Cassiterite is a minor constituent of many volcanogenic and some sedimentary-exhalative massive sul-fide deposits. For some years, it was an important by-product of mining at Kidd Creek and is a minor constituent of the remaining ores.

Crystals of artificial cassiterite
Mineralogical Magazine and Journal of the Mineralogical Society, 1947The crystals of artificial cassiterite, described below, were produced by volatilization of South African low-grade tin ores. In the sinter-pot method employed, air was blown through a charge of alternate layers of coke and of a 12 % metallic tin concentrate mixed with fine coke.

URANIUM IN CASSITERITE OF TIN DEPOSITS
International Geology Review, 1987The relations in space and time between uranium and tin mineralization are highly varied, ranging from close coincidence between the ore bodies to clear-cut separation. Such variation calls for refinement of their concepts on migration and accumulation of uranium and tin.

The spectrochemical determination of indium in cassiterite
Analytica Chimica Acta, 1956Abstract In order to determine the indium content of cassiterite specimens, a spectrochemical method, using tin as internal standard and the cathode-layer carbon arc, has been employed. The precision of the procedure is approximately 5 %.
