Abstract
Riešenie. sa týká sposobu získavania zinku z kalov získaných pri regenerovaní ťažkej tekutiny a z·. dplachovacích vůd produktov rozplavovania. Podstata riešenie'Spočívá v príprave :rmutu z kalov získaných regeneráciou ťažkej tekutiny, jej filtráciou cez filtračný materiál použitím oplachovacích vod, v působení vodného roztoku uhličitanu sodného na filtrát, získaný filtráciou rmutu a v oddělení zrazeniny od filtrátu filtráciou.Solution. relates to a process for obtaining zinc from the sludge recovered from the regeneration of heavy fluid and z. product leader wash separation. The essence of the solution in preparation: mash from sludge obtained by regeneration heavy fluid, by filtration through filter material using rinsing water, in an aqueous carbonate solution sodium per filtrate obtained by filtering the mash and separating the precipitate from the filtrate by filtration.
Description
Vynález sa týká sposobu získavania zinku z kalov získaných při regenerovaní ťažke] tekutiny, pripravene] z vodného roztoku ZnClž a z oplachovacích vod produktov rozplavovania uhlia, nerúd, alebo iných látok, založeného na rozdiele ich mernej hmotnosti.The invention relates to a process for recovering zinc from sludge recovered from the recovery of a heavy liquid, prepared from an aqueous solution of ZnCl2 and from the rinsing waters of coal, ore or other leaching products, based on the difference in their specific gravity.
Doteraz sa zinok z kalov získaných pri regenerovaný ťažkej tekutiny, pripravene] z vodného roztoku ZnCte a z oplachovacích vod produktov rozplavovania uhlia, nerúd, alebo iných látok nezískává a kaly, připadne oplachovacie vody, sa likvidujú.To date, zinc from sludge recovered from recovered heavy liquid, prepared from aqueous ZnCte solution and from the rinsing waters of coal, ore or other leaching products is not recovered and sludges or rinsing waters are discarded.
Nevýhodou tohto postupu je strata zinku, ako a] znečisťovanie životného prostredia.The disadvantage of this procedure is the loss of zinc, as well as environmental pollution.
Uvedený nedostatok je podlá vynálezu odstránený spůsobom získavania zinku, ktorého podstata spočívá v príprave rmutu z kalov získaných filtrováním ťažkej tekutiny cez filtračný materiál použitím oplachovacích vod produktov rozplavovania, dalej působení 10 až 20% vodného roztoku uhličitanu sodného a oddelenia zrazeniny s obsahom vyzrážaného zinku vo formě 2 ZnCO3. 3Zn(OH)2 od filtrátu filtrováním cez filtračný materiál.According to the invention, the above mentioned drawback is remedied by the method of recovering zinc, which is based on the preparation of mash from sludge obtained by filtering heavy liquid through the filter material using rinsing water of wash products, further treating with 10-20% aqueous sodium carbonate solution. 2 ZnCO3. 3Zn (OH) 2 from the filtrate by filtration through filter material.
Získavanie zinku z kalov pri regenerovaní ťažkej tekutiny, pripravenej z vodného roztoku ZnCh a z oplachovacích vůd produktov rozplavovania sa dosiahne filtrovaním znečistenej ťažkej tekutiny cez filtračný materiál, přípravou rmutu z kalu zaehyteného na: filtračnom materiálu použitím oplachovacích vůd produktov rozplavovania, filtrováním rmutu cez filtračný materiál, působením 10 až 20% vodného roztoku uhličitanu sodného na filtrát až do ukončenia zrážacej reakcie a oddělením zrazeniny s obsahom vyzrážaného zinku vo formě 2ZnCO3 . 3 Zn(OH jz od filtrátu, filtrováním cez filtračný materiál.The recovery of zinc from the sludge in the recovery of the heavy liquid prepared from the aqueous ZnCl solution and the rinsing leads of the leaching products is achieved by filtering the contaminated heavy fluid through the filter material, preparing the mash from sludge. by treating the filtrate with a 10-20% aqueous sodium carbonate solution until the precipitation reaction is complete and separating the precipitate containing the precipitated zinc as 2ZnCO3. 3 Zn (OH is from the filtrate, by filtration through a filter material.
PříkladExample
Prevedenie spůsobu získavania zinku z kalov pri regenerovaní ťažkej tekutiny a z oplachovacích vůd obsahujúcich ZnCh podfa vynálezu spočívá vo filtrácii znečistenej ťažkej tekutiny cez hustú filtračná tkaninu vo filtračnej odstredivke, príprave rmutu z kalu zachyteného na filtračnej tkanině použitím oplachovacej vody o zahuštění 100 g . 1_1, jeho filtrácii cez hustú filtračnú tkaninu vo filtračnej odstredivke, zrážaní zinku vo filtráte jeho premiešavaním s 10% vodným roztokami uhličitanu sodného v množstve 200 1 na 1 000 1 rmutu a oddělení zrazeniny s obsahom 2 ZnCO3 . 3 Ζη(ΟΗ)ζ od filtrátu, filtráciou cez hustú filtračnú tkaninu vo filtračnej odstredivke.An embodiment of the method of recovering zinc from sludge in the recovery of heavy liquid and of the ZnCl-containing rinsing lines of the invention consists in filtering the contaminated heavy liquid through a dense filter fabric in a filter centrifuge, 1 _1, the mixture is filtered through a thick filter cloth in the filter centrifuge, the precipitation of zinc in the filtrate with stirring a 10% aqueous sodium carbonate solution at 200 1 per 1000 1 of the mash and separating the precipitate containing 2 ZnCO3. 3 Ζη (ΟΗ) ζ from the filtrate, by filtration through a dense filter cloth in a filter centrifuge.
