Read MoreMar 12, 2021 The main types of iron ores are magnetite, hematite, limonite and chalcedony. According to the different properties of iron ore, the beneficiation methods are also different. Let's introduce the 4 Common Methods of iron ore concentrate process respectively.The dry method, in which high grade ore is crushed to remove waste material, leaving a low moisture content in the powdered ore. Iron concentrates obtained by the dry method are susceptible to spontaneous combustion because of the air already trapped within the concentrate.
