Natural magnetic minerals

1986
Iron, the pre-eminent seat of magnetism in natural minerals (Section 2.2.4), is the fourth most abundant element in the Earth’s crust. Consequently it is an important constituent of the majority of rocks found at the Earth’s surface. Along with the commonest crustal metal, aluminium, it combines with the two most plentiful crustal elements, oxygen and ...

Magnetic seeding flocculation of weakly magnetic iron minerals

International Journal of Mineral Processing, 1992
Abstract Magnetic seeding flocculation (MSF) has been proven as a successful pretreatment for High Gradient Magnetic Separation (HGMS) of weakly magnetic, finely-sized oxidized iron minerals such as specularite, limonite, and siderite. The utilization of an anionic polymer with an optimal molecular weight and degree of hydrolysis, sodium silicate ...

Magnetic Transitions in Minerals

Reviews in Mineralogy and Geochemistry, 2000
Magnetic minerals have fascinated man since they were first used as compasses by the Chinese over 4000 years ago. Their scientific study has given rise to the interrelated disciplines of mineral magnetism, rock magnetism, and paleomagnetism, which have contributed to some of the most important scientific discoveries of the last century and continue to ...

Rock magnetism and magnetic minerals

1983
Rock magnetism is the term commonly applied to the study of the magnetic properties of rocks and minerals, how these properties depend on factors such as grain size and shape, temperature and pressure, and the origin and characteristics of the different types of remanent magnetizations which rocks and magnetic minerals can acquire.

Magnetic Properties of Minerals

1994
All materials respond in some way to a magnetic field so that all minerals have magnetic properties. Minerals which contain no ions with uncompensated spins (e.g., an absence of, notably, the transition series elements) are diamagnetic. Those containing transition elements in low concentrations are paramagnetic.

Magnetic minerals and fluvial processes

1986
This chapter is concerned with particles in transit once they have reached a defined water course. Prior to the period of movement within a river channel, the particles will have been either released from the land surface and delivered to the channel by rainsplash, sheet erosion, rill and gully erosion or mass movement, or else removed from the channel

Mineral magnetism in marine sediments

1986
Of all the environmental systems considered in this book, the sea is, from a mineral magnetic point of view, by far the most complex. Potentially significant sources of magnetic minerals are at their most varied and include not only all those of relevance to lacustrine and atmospheric studies but also submarine and extraterrestrial sources.
