Notes on Cassiterite in the Malay Peninsula

Mineralogical Magazine and Journal of the Mineralogical Society, 1911
The following notes on some peculiar forms of cassiterite found in the Malay Peninsula will, it is hoped, prove of interest and an addition to our knowledge of the mineral.It is now well known that the most effective method of separating wolframite from eassiterite on a commercial scale is the electromagnetic process, which, in theory, lifts all the ...

Cassiterite Flotation with Sulphosuccinamate Collector

Geosystem Engineering, 1998
ABSTRACT Sulphosuccinamate is one of the best collectors used for flotation of cassiterite. The flotation results show that sulphosuccinamate displays strong collection and selectivity for cassiterite at lower dosage. The influence of other factors, such as depressants and metal cations on the cassiterite flotation has also been investigated.

Synthesis of cassiterite by pyrolysis of an aerosol

Solid State Ionics, 1993
Abstract SnO2 cassiterite has been synthesized by pyrolysis of an aerosol from different precursor solutions in order to study its influence on the microstructural and electrical properties. Hollow spherical particles are obtained whose crystallite average size increases by annealing.

Spectroscopic Analysis and Genesis of Cassiterite

1988
This paper deals with the spectral characteristics of cassiterite of four different genetic types by means of its absorption spectra in the ultraviolet — visible — infrared regions.

Inclusions in cassiterite and associated minerals

Economic Geology, 1960
A study was made of the inclusions in 133 specimens of cassiterite and associated minerals from world wide Sn deposits. From the distribution of inclusion types, it would appear that most pegmatitic Sn deposits have been formed from siliceous melts, but that most other types of deposits have been formed from aqueous solutions.

Hydrogen reduction of cassiterite concentrates

1991
Hydrogen as a reducing agent shows, compared to carbon monoxide, some advantages both metallurgically and environmentally. A very precise adjustment of the reduction potential with hydrogen-steam mixtures allows reduction conditions under which it is possible to produce a low iron-containing tin with high tin yield, though the tin is not completely ...

Cassiterite pseudomorphs from Bolivia

Mineralogical Magazine and Journal of the Mineralogical Society, 1907
One of the peculiarities of Bolivian tin-ores is the frequent occurrence of cindery and cellular masses of cassiterite, which is presumably of secondary origin. But, apart from impressions of quartz crystals, definite crystal-forms are rarely shown by this pseudomorphous cassiterite.The pseudomorphs to be now described are from the Tres Cruces district,
