Strontianite Cabonate Testing Prcess Materials And Methods
celestite concentrate with a particle size range of 100–500 µm beneficiated by shaking table (96% SrSO4 , 2% CaCO3 , 1% BaSO4 and 1% other impurities) and Na2 CO3 (98% purity) were used as the starting materials. The milling experiments were performed for different durations of time up to 16 hours and various Na2 CO3 :SrSO4 molar ratios of 1.05:1, 1.15:1 and 1.25:1 in a high-energy planetary ball mill (PM2400 model) with hardened steel chamber and balls 15 mm in diameter, under air atmosphere. The rotational speed and ball to powder weight ratio were 300 rpm and 30, respectively. The milled samples were washed with water to remove the produced Na2 SO4 phase during reaction to obtain a pure class="lazy" src="/myres/images/load_icon.gif" data-originalO3 nano-powder. Na2 SO4 leached by neutral water with the pH of 7 (solid/liquid ratio=1:30 g/mL, ambient temperature ~20 °C, time=30 minutes, stirring speed=300 r/min). Then, the solid and the liquid phases were separated, and the solid product was dried at 110˚C. The flowchart of the experimental work.
sulfate by a double decomposition reaction. Although the black ash method produces a higher purity class="lazy" src="/myres/images/load_icon.gif" data-originalO3 product, it is more energy intensive than the double decomposition process. Beside the two above commercial methods, there are several reports of the conversion of celestite to class="lazy" src="/myres/images/load_icon.gif" data-originalO3 by other methods including the high temperature and high-pressure reaction between celestite and either sodium or potassium carbonate and direct leaching of celestite with Na2S to produce class="lazy" src="/myres/images/load_icon.gif" data-originalO3.

Strontium occurs commonly in nature, averaging 0.04% of the Earth’s crust, making it the 15th element in abundance (MacMillan and others, 1994). Only two minerals, celestite (strontium sulfate) and strontianite (strontium carbonate), however, contain strontium in sufficient quantities to make its recovery practical. Of the two, celestite occurs much more frequently in sedimentary deposits of sufficient size to make development of mining facilities attractive. The major use of strontium (as carbonate) is in color television picture tube faceplate glass. Other important uses are in ferrite ceramic magnets, pyrotechnics, and signals. Smaller uses include chemicals, electrolytic production of zinc, and pigments and fillers.
