Mining is done by blasting , loading and hauling from the open pit before the uranium-bearing rock is processed to produce uranium oxide .
A NUCLEAR OPTION
A depressed global uranium market might have been a challenge for Rio Tinto but it presented a golden opportunity for China ’ s CNUC ( China National Uranium Corporation ) taking over in Namibia as the 68.62 % majority shareholder at Rössing Uranium in July

Now we need to consider plant readiness for possible mine life extension . The past two years there was a lack of capital investment in the operation and since we now have a new lease of life , we need to catch up on this backlog and get ourselves set up for the future to survive this depressed uranium market .”
