Abstract

The present invention relates to a method for recovery of valuable metals and a zeolite-containing material from a waste cathode material reaction vessel, in which valuable metals and a zeolite-containing material are recovered from a waste cathode material reaction vessel being discarded, and recycled as resources, thus reducing waste from the waste cathode material reaction vessel.

Abstract

The present invention provides a high value-added method for resource recovery from lithium sludge and fluoride sludge, and an economic sludge treatment method, wherein lithium fluoride (LiF), which is an insoluble lithium compound, is prepared by reacting lithium sludge with fluoride sludge, and then Li-Al layered double hydroxide (LI-Al LDH), which is an insoluble lithium compound, is prepared by reacting reaction filtrate with an aluminum compound, after which a conversion product is prepared by a sulfation reaction of the Li-Al layered double hydroxide (LI-Al LDH), which is an insoluble lithium compound, with a sulfuric acid compound, a lithium concentrate is prepared by leaching the conversion product with water, and then the lithium concentrate is recirculated as a lithium raw material to efficiently and economically recover lithium ions contained in the lithium sludge, or lithium fluoride (LiF) is prepared, and then lithium ions and fluoride ions are economically recovered from lithium sludge and fluoride sludge via additional precipitation/separation of lithium fluoride through the mechanical vapor recompression (MVR) of the reaction filtrate, and trace amounts of fluoride ions contained in the filtrate are reacted with a calcium compound to separate the filtrate into calcium fluoride precipitate and residual process water and discharge a small amount thereof.

Abstract

The present invention relates to an apparatus and a method for analyzing geophysical logging data using gamma rays, so as to predict lithofacies of strata by analyzing geophysical logging data, for lithofacies across a wide area, on the basis of data analyzed using gamma rays. The present invention comprises: a gamma-ray emission unit for emitting gamma rays by the nuclear transition of atomic nuclei; a gamma-ray transmission and reception unit for having the emitted gamma rays penetrate through an object and receiving the gamma rays to be received; and a logging determination unit which receives information about the waveforms and wavelengths of the gamma rays emitted by the gamma-ray emission unit, and information from the gamma-ray transmission and reception unit following the penetration of the gamma rays through the object, and produces geophysical logging data for which the information about the speeds, waveforms and wavelengths of the received gamma rays has been analyzed. Thus, the present invention can analyze geophysical logging data, for lithofacies across a wide area, on the basis of data analyzed using gamma rays, by clustering and patterning the results of the geophysical logging data for only significant strata, and can analyze strata with greater accuracy.
