Iyi mavuta irwanya nikel mugihe cyo kugabanya ibihe kandi ikarwanya umuringa mugihe cya okiside, irerekana nubwo irwanya kugabanya itangazamakuru kuruta okiside.
Ibikoresho byiza bya mashini kuva ubushyuhe bwa subzero kugeza kuri 480C.
Kurwanya neza acide sulfurike na hydrofluoric.Aeration ariko izavamo kwiyongera kwa ruswa.Birashobora gukoreshwa mugukoresha aside hydrochloric, ariko kuba umunyu wa okiside uzihuta cyane kwibasirwa.
Kurwanya umunyu utabogamye, alkaline na aside birerekanwa, ariko kutarwanya kuboneka kuboneka hamwe na okiside ya aside ya aside nka chloride ferric.
Kurwanya bihebuje kurwanya chloride ion guhangayika.
