▁are . ▁Because ▁of ▁the ▁improved ▁ad her ence ▁capacity ▁of ▁small ▁micro b ub bles , ▁the ▁s atur ation ▁of ▁the ▁introduced ▁air ▁as ▁well ▁as ▁the ▁reduction ▁cap ability ▁of ▁particles ▁lead ▁to ▁an ▁improved ▁susp ended ▁sol ids ▁reduction , ▁a ▁higher ▁sol ids ▁content ▁in ▁the ▁float ▁sl ud ge ▁and ▁a ▁more ▁stable ▁float ▁sl ud ge ▁on ▁the ▁surface ▁of ▁the ▁micro fl ot ation ▁cell . ▁ ▁A ▁difference ▁has ▁to ▁be ▁made ▁to ▁dispers ed ▁fl ot ation ▁used ▁in ▁min ing ▁industry ▁in ▁min eral ▁seg reg ation ▁processes ▁where ▁the ▁b ubble ▁are ▁bigger ▁being ▁ 5 0 0 - 2 0 0 0 ▁ μ m ▁in ▁size ▁and ▁volume ▁of ▁air ▁is ▁many ▁fol d ▁compared ▁to ▁the ▁water ▁volume . ▁Trad itional ▁D iss ol ved ▁Air ▁fl ot ation ▁( D AF ) ▁mainly ▁oper ates ▁with ▁b ubble ▁sizes ▁r anging ▁from ▁ 8 0 - 3 0 0 ▁ μ m ▁with ▁very ▁in hom ogeneous ▁b ubble ▁size ▁distribution . ▁A ▁major ▁difference ▁of ▁low ▁pressure ▁dissol ved ▁air ▁fl ot ation ▁and ▁other ▁fl ot ation ▁processes ▁lies ▁in ▁the ▁volumes ▁of ▁b ub bles , ▁amount ▁of ▁air ▁and ▁raising ▁spe eds . ▁One ▁macro ▁b ubble ▁can ▁be ▁ 1 0 0 0 ▁times ▁bigger ▁in ▁volume ▁compared ▁to ▁one ▁micro ▁b ubble . ▁And ▁vice ▁vers a ▁the ▁number ▁of ▁micro ▁b ub bles ▁can ▁be ▁ 1 0 0 0
