The extraction of alginates from brown algae is carried out in alkaline medium with sodium carbonate, sodium hydroxide or aluminum hydroxide, in several stages after the collected algae have been dried and shredded. The extract obtained is subjected to precipitation with sodium chloride or calcium an...
The introduction of sodium carbonate increased the active sites on the surface of smithsonite, while CO32− enhanced the chelation of calcium and sodium hexametaphosphate on the calcite surface. Mix ores and actual ore flotation will be studied further to verify the findings in this study, and ...
