Golide Pool Leaching Njira: Yogwira Ntchito ndi Njira Yoyenda

The njira yochotsera dziwe la golidi imadziwika chifukwa cha kuphweka kwake pakugwira ntchito, kugwiritsa ntchito zida zotsika mtengo, komanso kukwera mtengo kwake, zomwe zimathandizira kupanga mwachangu. Komabe, njirayi imafuna malo ochulukirapo chifukwa maiwe angapo amafunikira kuti amalize ntchito yotulutsa leaching. Komanso, si oyenera mitundu yonse ya golide ore. Nkhaniyi ifotokoza momwe zingakhalire, ndondomeko otaya wa njira yowotchera dziwe lagolide, pamodzi ndi kachipangizo kogwiritsa ntchito.

Kugwiritsa Ntchito Njira ya Gold Pool Leaching Method

Ores agolide oyenera njira yopangira dziwe ayenera kukwaniritsa mfundo zitatu nthawi imodzi. Choyamba, tinthu tating'onoting'ono tagolide tikuyenera kukhala ndi kukula kwabwino kofalitsa. Chachiwiri, miyalayi iyenera kukhala yotsika kwambiri kapena yotsika kwambiri. Chachitatu, miyala yokhayo iyenera kukhala yosalowerera bwino. Mwachitsanzo, chipewa cha iron oxide cap - mtundu wa ores wokhala ndi golide woyengedwa bwino ndi oxidized quartz vein ores okhala ndi golide woyengedwa bwino ndi oyenera kwambiri panjira yokhetsera dziwe.

Kuchuluka kwa kubweza kwa dziwe la leaching njira kumatha kufika 70 - 90%. Poyerekeza ndi njira zochotsera golide za CIL ndi CIP, njira yochotsera golide padziwe ili ndi ndalama zotsika, zomwe zimapangitsa kuti ikhale yankho lothandiza pakuwongolera chuma cha ores otsika. Kuonjezera apo, ntchito yake yosavuta imabweretsa kuchepetsa ndalama zogwirira ntchito. Komabe, njira yopangira ma pool leaching imabweretsa ndalama zambiri zomangira zam'tsogolo ndipo imafuna nthawi yayitali. Izi ndichifukwa choti ndikofunikira kupanga maiwe otayira ndi maiwe amadzimadzi osabala, kuwonetsetsa kuti akudontha - umboni komanso owuma. Pambuyo pake, miyalayo imayikidwa mu dziwe la leaching, ndipo yankho la leaching limakonzedwa mu dziwe lamadzi losabala lisanaponyedwe mu dziwe la leaching kuti lichotse. Patapita nthawi, njira yothetsera mimba imachotsedwa kuti isamutsidwe.

Kuyenda kwa Njira ya Gold Pool Leaching Njira

Golide pool leaching imachitika m'matangi a percolation leaching. Matanki amenewa akhoza kupangidwa ndi matabwa, zitsulo zachitsulo, kapena simenti. Pansi pa thankiyo ndi yathyathyathya kapena yopendekeka pang'ono, ndipo imatha kukhala yozungulira, yamakona anayi, kapena mainchesi. M'kati mwa thankiyo, pansi pamakhala bodza lopangidwa ndi asidi perforated - mbale zosagwira zimayikidwa. Nsalu yosefera imayikidwa pansi pake, ndipo gululi lopangidwa ndi matabwa kapena dzimbiri - zitsulo zosagwira ntchito zimayikidwa pamwamba pa nsalu zosefera. Pa nthawi ya leaching, ore amalowetsedwa mu thanki, ndipo wothandizira amawonjezedwa kuchokera pamwamba. Njira yothetsera leaching imachokera pansi pa bodza. Pansi pabodza amasefa ndikuthandizira zitsulo.

Mayendedwe a dziwe amayenda motere: Ore-onyamula golidi wophwanyidwa mpaka kukula kwake amalowetsedwa mu thanki ya leaching. Alkaline cyanide solution is added for soaking, during which gold is dissolved into the solution. After soaking for a certain period, once the concentration and grade of the liquid meet the requirements as detected, the gold - bearing solution (pregnant solution) is discharged from the bottom of the tank. Gold is recovered through displacement with zinc flakes (powder) (activated Carbon Kulowetsedwa kwa madzi kungagwiritsidwenso ntchito). Zotsalira zochotsedwa zimachotsedwa ku mankhwala oyeretsera madzi zisanatayidwe. Kuti muchotse cyanide kuchokera ku zotsalira zochotsedwa, zinthu monga sodium bisulfite ndi copper sulfate zitha kuwonjezeredwa.

Kuyenera kudziŵika kuti nthawi yofunika kuti percolation thanki leaching zimadalira osati pa Kutha mlingo wa zosungunulira pa mchere komanso pa malowedwe a zosungunulira mwa wosanjikiza zinthu. Mlingo wolowera makamaka umadalira zinthu monga kutalika kwa zinthu zomwe zapakidwa, porosity ya zinthu, kuchuluka kwa silt, kukhuthala kwa leaching agent, ndi chibadwa cha zinthuzo.
