World Bromine Resources Distribution And Flame Retardant

Bromine is an important chemical raw material, widely used in flame retardants, fire extinguishing agents, refrigerants, photosensitive materials, medicine, pesticides, oil fields and other industries. The natural resources of bromine mainly exist in seawater, underground concentrated brines, sediments of ancient oceans and salt lake water.

Bromine content in sea water accounts for 99% of the total global resources, the concentration of bromine is about 65ppm, while salt mine is only 0.1ppm, some areas 200~300ppm (such as underground brine in Laizhou, Shandong Province,China), in some foreign salt lake water 2000 to 12000 ppm 

The world production of bromine is about 800,000 tons/year. Among them, the annual output of the United States and Israel is more than 550,000 tons, ranking first and second in the world. China's annual output is about 160,000 tons, ranking third. Jordan and Japan are the fourth and fifth largest bromine producers in the world, with small quantities in Ukraine, Azerbaijan, India, Germany, Spain and Turkmenistan.
