A magnetic separator is provided in which a conveyor belt is conducted over a belt drum to transport relatively electrically conductive particles. A magnetic system consisting of permanent magnets or electromagnets is rotated at a high speed at an eccentric location within the belt drum so that an air gap between the outer surface of the magnet system and the inner surface of the belt drum is ...

Magnetic susceptibilities of minerals

Magnetic separation of minerals is a topic that is seldom reported in the literature for two reasons. First, separation data generally are byproducts of other projects; and second, this study requires a large amount of patience and is unusually tedious. Indeed, we suspect that most minerals probably are never investigated for this property.

A patent was awarded in England on a process for separating iron minerals by means of a magnet in 1792, and in this country a separator having a conveyor belt for presenting ore beneath electromagnets excited by cells was employed in …

Humorism

The concept of "humors" (i.e. chemical systems regulating human behaviour) became more prominent from the writing of medical theorist Alcmaeon of Croton (C. 540–500BC). His list of humours was longer than just four liquids and included fundamental elements described by Empedocles, such as water, air, earth, etc.Some authors suggest that the concept of "humours" may have origins in Ancient ...
