Bauxite is an aluminium ore found in deposits around the world. once the ore is mined out of the ground, the red bauxite rock is crushed and dissolved into a white alumina powder, using what is known as the bayer process. this alumina powder is then smelted into aluminium metal.
The country with the highest amount of bauxite reserves worldwide in 2018 was guinea. in that year, the reserves of bauxite in guinea amounted to about 7.4 billion metric dry tons.
The production of primary aluminum metal commences with bauxite ore, which is composed of hydrated aluminum oxide 40 to 60 mixed with silica and iron oxide. roughly 4 to 5 tonnes of bauxite ore are refined to produce approximately 2 tonnes of alumina. this 2 tonnes of alumina is smelted to produce approximately 1 tonne of aluminum. read more

The logic behind the buyout is that journey holds a 100 interest in five prospective vanadium and uranium properties in colorado and utah. according to alba, the projects are in and adjacent to the uravan mineral belt in which extensive prospecting, exploration, drilling and ore production has occurred for vanadium, uranium and radium since 1881.
The largest resources of vanadium are to be found in south africa and in russia. world production of vanadium ore is around 45.000 tonnes a year. production of the metal itself comes to about 7000 tonnes per year. watering is an important way in which vanadium is redistributed around the environment because venedates are generally very soluble.
