The present invention relates to a method for manufacturing high-purity carbonated lithium. Particularly, the method for manufacturing the high-purity carbonated lithium includes: removing magnesium and boron; separating and removing the remaining magnesium and boron; performing a powder concentration process which forms a powder through spray-drying; cleaning the powder to concentrate lithium; and carbonating the lithium ions using sodium carbonate (Na2CO3).
There is provided an apparatus and method for excavating a vertical hole capable of being used for excavation construction in places having complicated geological structures or in the winter. The apparatus and method for excavating a vertical hole may useful to vertically excavate the ground to form a guidance hole by using a cone-type bit installed in a lower rear end of a vertical excavation engagement unit engaged with a drill pipe, and injecting a high-pressure air-water (HPA-W) into a cone-type bit via a drill pipe and a vertical excavation engagement unit to grind and float slimes crushed by the cone-type bit with a high pressure, thereby to discharge the high-pressure air-water through a space between the guidance hole ad vertical excavation engagement unit
E21B 10/34 - Drill bits with leading portion, i.e. drill bits with a pilot cutterDrill bits for enlarging the borehole, e.g. reamers with expansible cutting tools of roller-cutter type
