What happens to aluminium in a magnetic field?

2010-12-10Thanks everyone; the answer I gave was what Dave said above (so I'm relieved!) - that basically a back-EMF occurs in the aluminium, leading to repulsion against the magnetic field. At school, for an A Level physics project, I designed an experimental system to brake a spinning aluminium disc using a controllable elecotromagnetic field.

Froth Flotation of Iron Ores

2012-01-024.2. Column Flotation The application of column cells in the mineral processing industry has gone from virtually zero in 1983 to wide acceptance in 1990[55-57]. The major operating difference between column flotation cells and mechanical flotation cells is the lack of agitation in column flotation which reduces energy and maintenance costs[58].

Rock magnetism

The more important minerals for rock magnetism are the minerals that can be magnetically ordered, at least at some temperatures. These are the ferromagnets, ferrimagnets and certain kinds of antiferromagnets. These minerals have a much stronger response to the field and can have a remanence . Diamagnetism

magnetic field

magnetic field, a vector field in the neighbourhood of a magnet, electric current, or changing electric field, in which magnetic forces are observable. Magnetic fields such as that of Earth cause magnetic compass needles and other permanent magnets to line up in the direction of the field. Magnetic fields force moving electrically charged particles in a circular or helical path.

Modifiers may activate poorly floating minerals such as sphalerite, or may depress certain minerals, so that a differential flotation can be performed on a complex ore. Chemicals that change the pH of the slurry are also used as modifiers. pH modifiers include lime, soda ash, sulfuric acid; can act as activators and/or depressants by controlling the alkalinity and acidity
