Laboratory studies included a selection of material, sample preparation, and optical sorting tests with magnesite, quartz, lignite, hematite, copper and gold ore samples. Experimental studies performed with different size fractions at varying feed rates were followed by evaluation of results with ROC (receiver operating characteristics) graphs.

Magnetic separator is a general term for equipment that uses magnetic force to separate magnetic substances from non-magnetic substances. They play a very important role in the beneficiation process. Most magnetic separators are used for ore selection, such as quartz sand, garnet, pyrite, hematite, limonite, siderite, etc.

Using a feed hopper, ore is introduced into the head end of the Condor Dense Medium Separator with a small amount of the dense medium slurry. The slurry is made up of a suspension of ferrosilicon or magnetite in water and is introduced through the medium inlets at the bottom end of the separator, countercurrent to the ore feed.

Abstract Beneficiation of low-grade ore is of critical importance in order to meet the growing demand for coal and mineral industries. But, low-grade ores require fine grinding to obtain the desired liberation of valuable minerals. As a result, production of fine particles makes the beneficiation process difficult through conventional gravity …
