Abstract

Keksintö kohdistuu menetelmään saostamalla tuotetun nikkelisulfidin pasuttamiseksi nikkelioksidiksi leijupetiuunissa. Saostettu, hyvin hienojakoinen nikkelisulfidisakka mikropelletoidaan ja mikropelletoitu sakka johdetaan leijupetikäsittelyyn. Leijupetikäsittely voi tapahtua yhdessä leijukerrosuunissa, jossa on kiertopeti tai kahdessa leijukerrosuunissa, joissa on kupliva peti.
