Dry mineral processing is related to the grade of iron in the mined ore. In Caracas, because of the high iron grade (more than 64%), the ore only needs to be crushed and screened, so it can be screened according to the size (particle size) of the ore. In Minas Gerais, iron exists in rocks known as "iron quartzite" with an average iron grade of 40%.
Currently, the development of iron ore of the Bakchar deposit (Tomsk region) is considered promising because of the extremely large reserves of iron ore. Ores of this deposit are related to the highgrade type and expected to have a magnetic concentration for iron extraction.

11 days ago · In December 2018, Vale spent US$500 million to acquire New Steel, which developed a widely patented dry iron ore processing technology. Montenegro told Reuters that many of the state''s wet concentration units have declining assets and mines with an average iron content of 40% need some form of processing to extract value.
DOVE Dry mining equipment and machinery (Dry Minerals Processing Plants) are designed and configured for classifiion, concentration, separation and recovery of metals and minerals concentrate in dry mode and without the use of water. Dry processing has many advantages over wet processing except when water is actually required prior to concentration and separation.

Mar 28, 2015 · Processes for Beneficiation of Iron Ores Crushing and grinding is a multi staged process and may use dry or wet ore feed. Depending on the ore hardness two, three, and sometimes four stages of crushing, are used to reduce the run of mine (ROM) ore to the required feed size. Primary and secondary crushing is normally by gyratory or cone

May 26, 2016 · Brazilian company New Steel have developed a new dry iron ore processing method to make mining more environmentally sustainable.
Hot direct reduced iron (HDRI) is DRI that is transported hot, directly from the reduction furnace, into an electric arc furnace, thereby saving energy. The direct reduction process uses pelletized iron ore or natural "lump" ore. One exception is the fluidized bed process which requires sized iron ore particles.
