Purification of thorium by solvent extraction

Sapurities such as rutile and silica are found in coinmercial monazite. The recovery of thorium from monazite sand generally involves two distinct operations: the opening of the sand to render the components soluble, and the separation of the thorium from the rare earths. There are only two methods of opening the sand which are of industrial

Is naturally occurring silica sand a desiccant?

Answer (1 of 2): No. Silica sand has a fairly low water absorption (typically less than 0.5% w/w), and thus little affinity for water. Silica gel is a very different animal.

Similarly, thorium was recovered from Egyptian monazite sand after alkaline treatment and leaching with alkaline carbonate solution (Ali et al., 2007). This process was further studied to accommodate various complex ores/concentrates. The treatment of Korean monazite concentrate using 50% NaOH (w/v) at 170 °C is also reported (Panda et al., 2014).

MINERAL SANDS

The occupational health issue of specific relevance to the mineral sands industry is radiation. Western Australian mineral sands deposits contain up to 10% heavy minerals, of which 1-3% is monazite. This in turn typically contains 5-7% of radioactive thorium and 0.1

Electrostatic separation enables the separation of a wide range of minerals and this example, separating Pyrite from Silica Sand, provides a good example of the separation process. A feed of conducting (Pyrite FeS 2 ) and non-conducting (Silica Sand SiO 2 ) powders is fed via a vibratory feeder onto an earthed, stainless-steel roll revolving at a pre-determined rate.
