    摘要: The present disclosure provides a method for adsorption/desorption of lithium ions from brine, which employs a counter current decantation process in adsorption/desorption of lithium ions, thereby achieving an adsorption rate of 65±5% and a desorption rate of 95±3%. The method includes supplying brine into one of a plurality of adsorption reactors, adsorbing lithium ions to an adsorbent by supplying the adsorbent to the adsorption reactor to which the brine is supplied and forcing the brine and the adsorbent to sequentially flow backwards inside the respective adsorption reactors, and desorbing the lithium ions from the brine by forcing the adsorbent to which the lithium ions are adsorbed to sequentially flow backwards inside a plurality of desorption reactors. Here, the brine and the adsorbent are stirred by a stirrer to maintain the adsorbent in an intermediate state instead of settling or floating inside the respective adsorption reactors.

    摘要: A method of removing lead sulfide contained in refined molybdenite powder concentrates (major component; MoS2) is provided. More specifically, in order to solve the problems associated with a leaching method using a leaching agent that is employed for conventional hydrometallurgical process, oxygen-free inert gas is circulated in a furnace for pyrometallurgical treatment to evaporate lead sulfide at high temperature, followed by condensing process to recover lead sulfide at low temperature. The method is characterized in that, it can reduce environmental contamination and can easily recover sulfides of valuable metals such as lead, indium, zinc and the like.

    摘要: Disclosed is the recycling of aluminum dross. Aluminum dross is crushed into particles which are size-classified on the basis of 1 mm. The aluminum dross particles equal to or smaller than 1 mm in size are leached with an aqueous sodium hydroxide solution to give a leachate which contains sodium aluminate as a result of the reaction the aluminum metal of the aluminum dross particles with sodium hydroxide. The aluminum dross particles greater than 1 mm in size are remelted to recover aluminum metal. In the leachate, a small quantity of aluminum hydroxide is seeded, followed by hydrolyzing the sodium aluminate to obtain aluminum hydroxide. Meanwhile, the leachate is filtered to obtain a residue. This residue is subjected to washing, drying and roasting. The mixing of the roasted residue with aggregate and alumina cement gives alumina castable refractories. It is economically very advantageous in that aluminum dross is reused as a raw material for aluminum hydroxide and for alumina castable refractories, instead of being discarded. Also, hydrogen gas can be obtained as a by-product in the process of recycling.
