Kuti vaparadzane nesimbi, vanofanira kutanga kuiswa mu mhinduro. Several kuparadzana nzira dziripo zvichienderana pahunhu musanganiswa; vaviri mumiririri nzira dziri fusion pamwe yavaibvisa peroxide, uchiteverwa nekunyungudika muna aqua regia, uye pakunyungudika musanganiswa chlorine pamwe hydrochloric asidhi. Mushure musanganiswa inonyungudutswa, iridium ari kuparadzaniswa kubva dzimwe nesimbi boka achishandisa electrorefining mhangura ammonium hexachloride uye nickel, uyewo selenium uye tellurium boka simbi anogara pasi muchitokisi sezvo anode madhaka, izvo zvinoumba pokutangira kuti dzokubvisa kwavo.
