    • Process for completely recovering the reusable components of an abrasive slurry used in slicing crystalline materials of silicon, quartz or ceramics when it becomes exhausted and enriched with undesired waste matter. The process consists of an initial centrifuge separation of the exhausted slurry as such and of a wet size-sorting treatment of the fraction containing the abrasive grains obtained from the centrifuge, carried out in a battery of hydrocyclones or centrifuges connected in series. The section for the recovery and purification of the abrasive grains comprises a multifunctional apparatus that performs all the required operations within a single pressure vessel. The process enables the complete recovery of the reusable abrasive grains contained in the exhausted slurry as well as of the suspending or cutting liquid of the abrasive slurry, in order to reuse both components in the manufacturing process. The invention also concerns an apparatus for carrying out the treatment of exhausted abrasive slurries according to the process described. ® KIPO & WIPO 2008
    • 用于在硅,石英或陶瓷的结晶材料切碎并且富含不想要的废物时,用于切割硅晶体材料的磨料浆料的可再利用组分的完全回收的方法。 该方法包括如此进行的排出的浆料的初始离心分离,以及在由串联连接的水力旋流器或离心机的电池中进行的含有从离心机获得的磨料颗粒的级分的湿式尺寸分选处理。 用于回收和净化磨粒的部分包括在单个压力容器内执行所有所需操作的多功能装置。 该方法能够完全回收包含在排出的浆料中的可重复使用的磨料颗粒以及研磨浆料的悬浮或切割液体,以便在制造过程中重新使用两种组分。 本发明还涉及根据所述方法进行处理耗尽的磨料浆料的设备。 ®KIPO&WIPO 2008

    • A process is provided for the direct recovery of non-ferrous metals (nickel, cobalt, copper etc) from raw materials such as ores, concentrates, semiproducts and/or solutions by ion exchange. A non-ferrous ore or concentrate is leached with a mineral acid to dissolve the metals. The pH of the resulting leach slurry is adjusted to 1.0 - 5.0 using some alkaline agents as limestone, sodium hydroxide etc. Non-ferrous metals are absorbed from this leach slurry with ion-exchange resin, which selectively loads the non-ferrous metals and has the structure: formula (1) wherein the ratio of N : M : P : R is within the ranges of 3-4 : 64-70 : 25-30 : 2-2.5 The loaded resin is separated from the exhausted leach slurry. The loaded sorbent is stripped with an acidic or ammonia-ammonium carbonate solution. The stripped resin is returned to the loading cycle. The non-ferrous metal can be recovered in substantially pure from the eluate by some known processes. The metal- depleted slurry proceeds to waste treatement and disposal.

    • Disclosed herein are a high-sensitivity method and apparatus for monitoring the concentration or inflow of impurities in circulating water of a circulating water system, which can remarkably improve the measurement sensitivity by converting carbonate ions of low conductivity into chlorine or sulfate ions of increased conductivity, and which can measure the inflow of air or organic substances and the amount of inflow in a simple and efficient manner in real-time. The method of the present invention comprises the steps of: increasing a content of strong acids in sample water and thus increasing equivalent conductivity of the impurities, by utilizing cation exchange resin together with anion exchange resin, in which cations of the sample water are adsorbed on the cation exchange resin to form strong acids while weakly acidic anions of low dissociation degree in the sample water are adsorbed on the anion exchange resin to form strong acids; and measuring the increased conductivity of the impurities.
