Pyrolusite,cryptomelane,coronadite,psilomelane,nsutite manganese spar,manganite and manganocalcite were found in the E′rentaolegai silver deposit.

勒盖银床出现物主要为软、、六方、铅、钾、菱、铁菱及方解石。

The arsenolite cinders were treated by the processes of oxidizing roasting-pyrolusite pulp absorption,magnetizing roasting-magnetic separation and acid leaching.

采用氧化焙烧—软浆吸收、磁化焙烧—磁选、酸浸工艺处理砷华废渣。
