Associations of ore minerals in the deposits of the Seinäjoki district and the discussion on the ore formation [PDF]

Bulletin of the Geological Society of Finland, 1983
The mineral associations of the antimony deposits in the Seinäjoki region (Finland) are described on the basis of microprobe investigations. There are two ore associations: quartz-antimony and pyrrhotite- antimony.

Efficacy of Thermotherapy to Treat Cutaneous Leishmaniasis Caused by Leishmania tropica in Kabul, Afghanistan: A Randomized, Controlled Trial [PDF]

, 2005
BACKGROUND: Pentavalent antimony is the agent recommended for treatment of cutaneous leishmaniasis (CL). Its use is problematic, because it is expensive and because of the potential for drug-associated adverse effects during a lengthy and painful ...

Effects of Goethite/Birnessite on Antimony Speciation in Yellow Soil from an Antimony Mining Area under Simulated Natural Conditions

Yankuang ceshi
The antimony (Sb) mining area and its surrounding soil are severely polluted with antimony, and the degree of antimony pollution is closely related to its speciation in the soil.

First-principle study of antimony doping effects on the iron-based superconductor CaFe(Sb$_{x}$As$_{1-x}$)$_{2}$

, 2015
We study antimony doping effects in the iron-based superconductor CaFe(Sb$_{x}$As$_{1-x}$)$_{2}$ by using the first-principle calculation. The calculations reveal that the substitution of the doped antimony atom into As of the chainlike As layers is more

Thermogravimetric and distillation studies on mercury, antimony and arsenic sulfides [PDF]

, 1975
Thermogravimetric studies were made on naturally occurring sulfides of mercury, antimony and arsenic to determine activation energies and Arrhenius rates of reaction in vacuum and in atmospheres of air and nitrogen. Of the three sulfides only antimony
