ABSTRACT  Full text (pdf)

In this article are presented the analysis of ore losses in bauxite underground exploitation as well as the manner and possibility to increase recovery factor of ore deposit and exploitation with minimum of diluted ore with overburden. The largest losses of ore are the caracteristics of the mining process itself and the results of model studies of the ore losses and recovery for the various parameters of sublevel - transverse caving method are given in the article.
 
Key words: ore losses, ore recovery, mining method
