Apstrakt

Dijamantske krunice koje se koriste za istraživačko-geološko bušenje koje se dobijaju sinterovanjem čestica volfram karbida i kobalta (tvrdi metal) i gvožđa sa dijamantima imaju široku primenu u geologiji i rudarstvu. Prema istraživanjima, troškovi proizvodnje kobalta i volframa iz ruda su četiri puta veće u odnosu na troškove reciklaže iz tvrdog metala.U radu je opisana prva faza reciklaže dijamantskih krunica i dobijanje volframa u obliku natrijum vollframata.
