Susan Featherstone, in A Complete Course in Canning and Related Processes (Fourteenth Edition), 2015. 4.4.3 Microwave processing. Microwave processing, like ohmic heating, is an electrical heating system that destroys microorganisms via thermal effects.Frequencies of 950 and 2450 Hz are used to excite polar molecules that produce thermal energy and increase temperature.

Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.The primary operations are comminution and concentration, but there are other important operations

Microwave technology is used in two ways for measuring moisture content of various types of ores, coal and other minerals: By reflection or resonance; Transmission; The technology "by reflection" means that the microwave is emitted into the material bed and the analysis is made on the microwave frequency that is reflected from the material to be measured. The technology is limited to

depth, other factors which affect microwave food processing are microwave oven design (oven size and geometry), microwave frequency, placement of food material inside the oven, moisture content, density, composition, load, shape and the size of food materials [Icier and Baysal, 2004a]. In general, amount of moisture or water content in a food material plays a deciding factor in determining the

Using this process, it was possible to weaken the rock face to the depth of approximately a foot at a time, after which the soft ore was mined and when the harder rock face was again encountered, fire setting was again employed (Cowen, 1999)4. Archeological evidence supports the notion that the practice of fire-setting was a worldwide

Recent research developments have suggested that microwave assisted comminution could provide a step change in ore processing. This is based on the fact that microwave-absorbent phases within a multi-mineral ore can be selectively heated by microwave energy hence inducing internal stresses that create fracture. A detailed review of existing literature revealed that little or no information is
