Chemical element analysis of salt in China
The chemical products of salt in China are dominated by potassium chloride, industrial bromine, ahydrous sodium sulfate and magnesium oxide, with a scaled production of some new chemical products such as potassium sulfate being gradually established. In 1997, China’s total output of the chemical products of salt amounted to 1,563,102 tons, 21.49% up over 1996, including 41,941 tons of potassium chloride, 50,882 tons of industrial bromine, 846,160 tons of ahydrous sodium sulfate, 378,524 tons of magnesium chloride and 245,595 tons of other products. The quality of the main chemical products of salt is as follows:
1) Potassium chloride.
Quantity represented (quantity of salt products represented by quality determinations, the same below) 38,716 tons, rate of H-1 grade 96.72%, and chemical composition: potassium chloride 96.23%, calcium chloride 1.74%, Ca-Mg ions 0.25%, sulfoacid radical 0.12% and insolubles 0.04%.As the professional manufacturer of complete sets of mining machinery, such as ball mills,belt conveyor, Henan Hongxing is always doing the best in products and service.limestone rotary kiln:http://www.hxjq-crusher.com/23.html.ore separating line:http://www.hxjqchina.com/.
2) Bromine.
Quantity represented 50,038 tons, rate of H-1 grade 100%, and che-mical composition: bromine 99.76% and chlorine 0.04%.
3) Ahydrous sodium sulfate.
Quantity represented 760,976 tons, rate of H-1 grade 79.75%, and chemical composition: sodium sulfate 85.77%, Ca-Mg ions 0.76%, chlorides 1.60%, iron 0.002% and water-insolubles 1.62%.
4) Magnesium chloride. Quantity represented 378,440 tons, rate of H-1 grade 92.56%, and chemical composition: magnesium chloride 46.02%, chlorides 0.65%, and sulfoacid radical 2.22%.
