copper mines within the RTB Company ranked among the highest-grade copper mines (on average 5 – 6 % Cu in the ore). At the end of the century, the average Cu content in the RTB Bor mines fell to less than 0.4 %, which is illustrated by Fig. 1. Consequently, it is now ranked among lower-grade copper mines in the world [9].
