Decision for Mining and Dressing of Low-grade Ores by Breakeven Grades
The method of breskeven grades is used to decide if the black-spot ores are economic or not in Yichun Ta & Nb Mine and make decision of mining and dressing.If the grades of black-spot ores are lower than present balance grades, the mines which are mining and dressing the ores will suffer loss.The result is that the blackspot ores are sub-marginal economical resources and are not worth exploring.
