Mhangura slag kazhinji yakasviba kana yebrown, iyo pamusoro ine simbi inopenya, iyo yemukati chimiro chakanyanya vitreous, chimiro chakaomarara, chakaoma uye chine brittle, uye chimiro chemakemikari chakanyanya kuoma. Kubva pane zvemhangura zvevamwe muhurombo hwemhangura ore (Cu <1%), mamwe ari pakati pemhangura ore (Cu1 ~ 2%), mamwe ari mumhangura yakawanda (Cu> 2%), FeSi02, CaO. , AL203 yemukati yakakwira, inoverengera inopfuura 60% ye slag, iyo yakawanda yakawanda yemaminerari inoumbwa nesimbi peridotite, inoteverwa nemagnetite, kune nhamba shoma yetsinga inoumbwa ne vitreous body.
Xiye akagadzira uye akaziva tekinoroji yemhangura tailing slag kurapwa ne electrothermal nzira, inochengetedza nharaunda, inodzoreredza tsvina yakasimba uye inoshandura marara kuita pfuma.
Iyo tekinoroji tekinoroji inotora yakasarudzika choto yemagetsi yakagadziridzwa neXiye yakazvimiririra, uye inotora yakasarudzika yekuchaja maitiro, nekubudirira kuona tekinoroji yekurapa mhangura yekuisa slag nechoto chekutanga chemagetsi muChina.
