Magnetic and Gravity Methods in Mineral Exploration: the ...

Magnetic methods are more popular in mineral exploration than gravity, not least because magnetic data can be quickly recorded from the air and in conjunction with other geophysical surveys. Land gravity surveys, by contrast, may require greater field efforts (Figs. 1, 5 and 6), more time, and more commitment of scarce capital.

Potash Processing in Saskatchewan CIM Bulletin

The sizing of the mill feed ore is a compromise between maintaining the potassium chloride in as large a size as possible, obtaining a good liberation from the sodium chloride and facilitating the scrubbing of the insolubles released during the process. The run-of-mine ore is produced by continuous miners with a top size of about 1,500 mm, and

Characteristics Of Dry Magnetic Separators

 · Dry magnetic separators are particularly suitable for ore dressing of coarse-grained minerals. For example, the upper limit of ore particle size can reach 350(magnetic pulley) during magnetite ore dressing, and the upper limit of suitable dry magnetic separation iron particle size for quartz and feldspar is generally not more than 1mm.

Magnetite

Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe 3 O 4 is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally occurring minerals on Earth. Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of ...
