CST processing requires grinding of the ion exchange media, handling of solids with high cesium loading, and handling of liquid wash and conditioning solutions. RF processing requires handling and evaporation of cesium eluates, disposal of spent organic resin, and handling of the various liquid wash and regenerate solutions used.
A homogenous dispersion of the tungsten nanoparticles are then prepared in a liquid solvent medium, e.g. toluene, using a wet milling method with small diameter grinding media. Typically the milling media would be zirconia-based and have a diameter of less than 0.3 mm.
Among the several nuclides, especially cesium (137 Cs) released due to that nuclear accident, is considered one of the precarious elements of the environment. Moreover, the extended half-life (30.4 years), high solubility in aquatic media and transportability through the food chain has made it much hazardous for the human health.
By grinding micro-sized coarse powder with grinding beads of 50 μm in diameter, the mean hydrodynamic diameter of Cs 0.33 WO 3 powder could be reduced to about 50 nm in 3 h, and a stable aqueous dispersion could be obtained at pH 8 via electrostatic repulsion mechanism.

Ore is harvested with underground machinery and hoisted to the surface for processing using various techniques, such as gravity concentration, flotation and grinding. Pollucite is mined, ground to 200 mesh, and processed into cesium formate and fine cesium chemicals.
Cesium reacts violently with water and due to its reaction with oxygen, should be stored in the absence of air. Located in the lower left-hand corner of the periodic table, cesium is the most electropositive element and has the lowest ionization potential.
