Phys 34 questions Flashcards | Quizlet

"Chain reactions would occur in naturally occurring uranium ore deposits if all uranium atoms fissioned so easily. Fission occurs mainly for the rare isotope U-235, which makes up only 0.7% of the uranium in pure uranium ore. In today's world, naturally occurring uranium is too "impure" to undergo a chain reaction spontaneously."

Magnetic separation - Wikipedia

Magnetic separation is the process of separating components of mixtures by using magnets to attract magnetic materials. The process that is used for magnetic separation detaches non-magnetic material with those who are magnetic. This technique is useful for not all, but few minerals such as ferromagnetic (materials strongly affected by magnetic fields) and paramagnetic (materials that are less ...
