O le Phosphate o se tasi o mea masani o le toetoe lava o meaʻai uma ma e faʻaaogaina lautele i le gaosiga o meaʻai e avea o se meaʻai taua ma faʻaopoopoga aoga. O le phosphate masani o le phosphate rock (o loʻo i ai le calcium phosphate). O le sulfuric acid e tali atu i le papa phosphate e maua ai le calcium dihydrogen phosphate ma le calcium sulfate e mafai ona mitiia e laau e maua ai le phosphate. E mafai ona vaevaeina Phosphates i orthophosphates ma polycondensed phosphates: o phosphates o loʻo faʻaaogaina i le gaosiga o meaʻai e masani lava o le sodium, calcium, potassium, ma le uʻamea ma le zinc salts e fai ma faʻamalosia meaʻai. E masani ona fa'aogaina mea'ai-grade phosphates E silia ma le 30 ituaiga. O le sodium phosphate o le ituaiga taumafa autu lea o mea'ai phosphate. Faʻatasi ai ma le atinaʻeina o tekinolosi gaosi meaʻai, o le faʻaaogaina o le potassium phosphate e faʻateleina foi i lea tausaga ma lea tausaga.
