describe extraction of vanadium from its ore

Vanadium processing

Vanadium is extracted from carnotite as a coproduct with uranium by leaching the ore concentrate for 24 hours with hot sulfuric acid and an oxidant such as sodium chlorate. After removal of solids, the leachate is fed into a solvent extraction circuit where the uranium is extracted in an organic solvent consisting of 2.5-percent-amine–2.5-percent-isodecanol–95-percent-kerosene.

Wolframite is removed by electromagnetic separator. Get price

Magnesium: extraction

Magnesium: extraction; Brife introduction; Magnesium is found in solution in sea-water (about 1.3 kg m-3 magnesium) and in natural brines. It is also found extensively in the ores magnesite (MgCO3) and dolomite (MgCO3.CaCO3). Both of the two types of resources can be used as raw materials to manufacture magnesium metal. Get price

what is the main ore of mercury explain how mercury is

Main ore of mercury is cinnarbar, HgS. The extraction of mercury from cinnabar ore involves two steps: 1. The concentrated mercury (II) sulphide ore is roasted in air to form mercuric oxide (HgO). 2. This Mercuric oxide formed is then reduced to mercury on further heating to about 300 o C. Get price

The Properties and Applications of Platinum

Aug 21, 2020Extracting platinum from ore is both capital and labor-intensive. It can take up to 6 months and 7 to 12 tons of ore to produce one troy ounce (31.135g) of pure platinum. The first step in this process is to crush platinum containing ore and immerse it in the reagent containing water; a process known as 'froth flotation'. Get price

How do we extract minerals?

Large tabular-shaped ore bodies or ore bodies lying more than 1,000 feet (300 m) below the surface are generally mined underground as well. The rock is drilled and blasted, then moved to the surface by truck, belt conveyor, or elevator. Once at the surface, the material is sent to a mill to separate the ore Get price

Vanadium Extraction from a Fe–V (2.0 Mass%)–P (0.1 Mass

Nov 16, 2017An innovative and sustainable way for production of vanadium is to co-process vanadium titanomagnetite ores with vanadium-bearing slag from steel industry, via reduction, producing a hot metal containing about 2 mass% vanadium, 0.1 mass% phosphorus, and 0.4 mass% silicon. A vanadium-extraction method was developed for these hot metals using a semi-industrial-scale Get price

How is aluminium extracted from its ore?
