The present invention relates to a method and an apparatus to dry concentrates which grind mined rocks containing mineral resources mined in a mine or the like to certain sizes, and removes impurities from the mined rocks through a wet sorting process to separate water and concentrates from concentrates of upgraded sludge form. According to the present invention, it is possible to dehydrate and dry to a moisture content of 6% or greater and less than 8% by removing moisture from the sludge concentrates containing a large amount of moisture using dry air under high pressure; operates in an environmentally friendly manner by improving a work environment as toxic gas is not generated; ensures durability as mechanical errors due to dust or the like are few; and drastically decreases costs to produce minerals because heating is unnecessary. |
