Co-applied with sulfide reagent, SEX/PEX is most useful in the flotation of oxide ore of copper, lead and etc for maximum selectivity. SEX/PEX is also used as the precipitator and the comparator of copper and nickel in analytical chemistry; and as the precipitator in hydrometallurgy and the accelerator in vulcanization of rubber.
Packaging: 120kg net/iron drum; 850kg net/ wooden box; 50kg net/woven bag.
Storage: SEX/PEX should be stored in a cool dry well-ventilated area.
