at least 10 kg/tonne of ore and leaching and sepn. are pref. carried out at 40-90 deg.C. The gypsum employed is pref. obtd. by adding CaO or CaCO3 to liq. effluents from which uranium has been removed. The invention increases the yield of dissolved U, and reduces the amt. of ...
The demand for a Bre-X site tour was so great that there was no room on their first large investor tour, but regardless, I jumped on a plane and flew to the other side of the world with no permission to go to site. While in Jakarta, I met the Bre-X office manager in hopes of ...
Among Afghanistan’s many natural resources are coal, copper, iron ore, lithium, uranium, rare earth elements, chromite, gold, zinc, talc, barite, sulfur, lead, marble, precious and semi-precious stones, natural gas, and petroleum. In 2010, US and Afghan government officials estimated that th...
Of these two I favor molten salt reactors because the salts are not reactive in air and thus do not start fires if you have a plumbing leak, unfortunately this IS a problem with sodium cooled reactors. The reason some designs favor sodium is that it is easier to find container materials t...
Already industrialized, South Africa is rich in gold, diamonds, coal, uranium, thorium, wool, and oil from the Kalahari Desert. It would be pointless to build a federated state, that would make Africa’s potential for economic and industrial growth a reality, without the muscle to protect it...

The ore is leached with H2SO4 soln., and the solids removed, e.g. by filtration.Before the filtrate is used for winning uranium, an alkali is added to obtain pH 1.5- 3.5 in the presence of ferric ions providing a molar ratio(MR) of ferric ions/As above 1.0, so the As is pptd....
