The present invention relates to a concentrate drying method and a concentrate drying apparatus which pulverize mined rocks including mineral resources mined from a mine or the like to a certain size, remove impurities from the mined rocks through a wet sorting process, and separate water and concentrate from a concentrate in the form of sludge that has been upgraded in quality. According to the present invention, there are the effects in that high pressure dry air can be used to remove moisture from concentrate in the form of sludge containing a large amount of moisture to dehydrate and dry the concentrate to a low percentage of water content (below 6% to 8%), because there are no toxic gases emitted, environmentally friendly work is possible through an improved work environment, mechanical malfunctions due to dust, etc. are reduced so as to ensure durability, and because heating is unnecessary, the cost of mineral production can be significantly reduced. |
