2016-11-28· This reaction has been used as a gravimetric method for determining antimony, bubbling HS through a solution of Sb(III) compound in hot HCl deposits an orange form of SbS which turns black under the reaction conditions.
The effects of arsenic and antimony sulphide minerals on the extraction of gold from a synthetic ore consisting essentially of free gold and glass sand were investigated. The amount of mineral added in each test was such that the synthetic ore assayed 0.25% As or 0.25% Sb.
This reaction has been used as a gravimetric method for determining antimony, bubbling H 2 S through a solution of Sb(III) compound in hot HCl deposits an orange form of Sb 2 S 3 which turns black under the reaction conditions.
Antimony and Arsenic Sulfide Scaling in Geothermal Binary Plants Kevin Brown GEOKEM, P.O. Box 30-125, St Martins, Christchurch 8246, New Zealand [email protected] Keywords: Antimony, arsenic, stibnite, binary, scaling ABSTRACT With the advent of acid dosing for silica scaling control, and the increased utilisation of binary plants, the incidence of antimony sulphide scaling has become a ...
Deposition of antimony sulfide thin films by melt method The melt method was employed to deposit thin film onto glass substrates. The antimony benzoate complex was spread onto the glass substrate and put it in the furnace under a nitrogen atmosphere at different (300, 350 and 400 °C) temperatures.
Antimony may be separated and weighed for analysis as the sulfide, Sb 2 S 3. Alternatively, the sulfide may be converted to the oxide and, after careful ignition, weighed as Sb 4 O 6 . Numerous volumetric methods are also available, including several methods of oxidizing antimony in the +3 oxidation state with potassium permanganate, potassium bromate, or iodine .
Antimony sulfide and antimony were confused sometimes in antiquity. There is a question over what "stibium", the original name of antimony, meant. There is a question over what "stibium", the original name of antimony, meant.
WO2014054112A1 - Method for producing . A method for producing antimony trisulfide is developed, in which the resultant antimony trisulfide contains impurities, i.e., lead, arsenic and crystalline silica, in a relatively low amount, and by which it becomes possible to produce antimony trisulfide at low cost.
Antimony Compounds: Fatalities from antimony poisoning are rare. Acute systemic exposure to antimony compounds may cause loss of hair, dry scaly skin, and weight loss. Damage to the heart, liver, and kidneys can occur, and death from myocardial failure may follow.

Antimony is a metalloid. A metalloid is an element that has characteristics of both metals and non-metals. The metalloids can be found on either side of the staircase line on the right side of the periodic table (with the exception of aluminum, which is not considered a metalloid).
The material they were using, antimony sulfide, is a molten semiconductor, which normally would not allow for the kind of electrolytic process that is used to produce aluminum and some other metals through the application of an electric current.
