Mineralogy and uranium leaching response of

01-01-2008· 1.. IntroductionGold deposits in the Vaal River region, South Africa, also contain uranium-bearing minerals. Although the uranium content of the ore is very low by international standards (it averages only 0.3 kg U 3 O 8 /t), recovering uranium as a by-product of gold production improves the overall processing economics. The benefit is primarily due to the additional gold extraction following
