Phosphate ndechimwe chezvakasikwa zvechikafu chinenge chikafu uye chinoshandiswa zvakanyanya mukugadzira chikafu sechinhu chakakosha chekudya uye chinoshanda chekuwedzera. Iyo inowanzoitika phosphate is phosphate rock (ine calcium phosphate). Sulfuric acid inopindirana nedombo rephosphate kugadzira calcium dihydrogen phosphate uye calcium sulfate inogona kutorwa nezvirimwa kugadzira phosphate. Phosphates inogona kukamurwa kuita orthophosphates uye polycondensed phosphates: iyo phosphates inoshandiswa mukugadzira chikafu inowanzova sodium, calcium, potassium, uye iron uye zinc munyu sezvivakwa zvinovaka muviri. Inowanzo shandiswa chikafu-giredhi phosphates Kune anopfuura makumi matatu marudzi. Sodium phosphate ndiyo inonyanya kushandiswa mhando yemhando yezvokudya zvemumba. Nekuvandudzwa kwehunyanzvi hwekugadzira chikafu, kushandiswa kwe potassium phosphate kuri kuwedzerawo gore negore.
