Thorium processing, preparation of the ore for use in various products. Thorium (Th) is a dense (11.7 grams per cubic centimetre) silvery metal that is softer than steel. It has a high melting temperature of approximately 1,750 °C (3,180 °F). Below about 1,360 °C (2,480 °F), the metal exists in the
In the distant past the abundances of thorium and uranium were enriched by the decay of plutonium and curium isotopes, and thorium was enriched relative to uranium by the decay of 236 U to 232 Th and the natural depletion of 235 U, but these sources have long since decayed and no longer contribute.

Regenerant waste from the uranium removal system is a concentrated form of the uranium and must be disposed of properly. For the homeowner, the spent solution is usually discharged the same way softener brine is discharged, the net amount of uranium reaching the disposal point is the same whether or not a uranium removal unit is in place.
Uranium ore is mined in several ways: by open pit, underground, in-situ leaching, and borehole mining (see uranium mining). Low-grade uranium ore mined typically contains 0.01 to 0.25% uranium oxides. Extensive measures must be employed to extract the metal from its ore.
Uranium from rare earths deposits: A large amount of uranium is in rare earths deposits, and may be extracted as a by-product. Higher uranium prices and geopolitical developments have enhanced the economic potential for recovering these.

Thorium-230 has many research applications, but there is not a commercial source of this isotope. However, since 230 Th is part of the 238 U decay chain, it can be separated from naturally occurring uranium. In this work, a novel procedure was developed to separate thorium from uranium ore, consisting of leaching, liquid–liquid extraction, precipitations and ion exchange chromatography.

As carnotite is free from thorium, no complications arise from the presence of mesothorium in the radium salts. PART 5: Processing, Extraction & Recovery of RADIUM from Uranium Ore #5. PART
Significant concentrations of uranium occur in some substances such as uraninite (the most common uranium ore), phosphate rock deposits, and other minerals. Natural uranium consists primarily of isotope 238 U(99.28%), therefore the atomic mass of uranium element is close to the atomic mass of 238 U isotope (238.03u).
