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.

Xanthan gum based investigations into the surface chemistry of cassiterite and beneficiation of cassiterite tailings

Mineral Processing and Extractive Metallurgy Review, 2020
The surface chemistry of cassiterite mineral and selective dispersion-flocculation-flotation studies on cassiterite tailings have been investigated using xanthan gum.

Geochemistry of some Cornubian cassiterites

Mineralium Deposita, 1979
Magnetic 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, 2014
Polycrystalline 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.

Crystals of artificial cassiterite

Mineralogical Magazine and Journal of the Mineralogical Society, 1947
The 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.

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,

Cassiterite fingerprinting by LA-ICP-MS

Journal of Analytical Atomic Spectrometry, 2013
Cassiterite (SnO2) has been specified as a ‘conflict mineral’ by a U.S. Government Act. This requires all companies that use tin in their products to verify that this tin does not originate from conflict regions in the Democratic Republic of the Congo where an ongoing violent conflict is fuelled by those minerals.

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 as a Carrier of Palaeomagnetism

Nature, 1965
IN an attempt to extend the scope of palaeomagnetism when investigating endogenous geological processes1,2 the magnetic properties of high-temperature minerals were investigated. The main objective was to find other minerals not yet examined from this point of view which would be amenable to palaeomagnetic examination.
