Most of the iron ore contains magnetism,limonite is also a type of iron ore, but compared to iron ores with astonishing magnetic content such as magnetite, it belongs to weakly magnetic iron ores.So,this provides the possibility for the application of new ore pre-sorting technologies, such as "visible light artificial intelligence sorting" and "X-ray intelligent sorting".

一、The traditional sorting difficulties of limonite

Due to the complex composition of limonite, its physical properties also vary greatly. This has led to many difficulties in its sorting process.Mainly including: "low iron content, large changes in composition, fine embedding particle size, and low selection indicators".

Due to the high content of water and impurities in brown iron ore, it is usually necessary to undergo enrichment treatment in industry to improve its economic value.

二、The application prospects of photoelectric sorting technology in the enrichment and sorting of limonite

"visible light artificial intelligence sorting" and "X-ray intelligent sorting" all have their own advantages.Derived from them are the "AI ore sorting machine" and the "X-ray intelligent sorting machine"。For limonite, if there is a clear contrast between its color or luster and that of vein minerals, then an AI intelligent sorting machine may be a suitable choice.

For certain types of limonite, especially those with significant density differences from vein minerals, X-ray intelligent sorting machines may be a suitable choice.So,The choice between photoelectric intelligent sorting or X-ray intelligent sorting depends on the specific properties of limonite and the expected sorting results.
