Namibia’s finance minister said uranium miners are waiting for prices to recover before reviving projects in Africa’s biggest producer of the ore, which is needed for nuclear power in a world shifting away from fossil fuels. The semi-arid southwest African nation is investing in water facilities and is planning a second desalination plant to supply mines in the dry Erongo region in anticipation of higher uranium prices attracting investors, according to Finance Minister Ipumbu Shiimi.
