Cov kws tshawb fawb suav tau ua tiav ib hom huab cua crusttsawg ntiaj tebore hluav taws xob tsav mining thev naus laus zis, uas ua rau lub ntiaj teb tsis tshua muaj kev rov qab los ntawm kwv yees li 30%, txo cov ntsiab lus impurity li ntawm 70%, thiab txo lub sijhawm mining los ntawm 70%.Qhov no tau kawm los ntawm tus neeg sau xov xwm ntawm lub rooj sib tham kev soj ntsuam ntawm kev tshawb fawb thiab thev naus laus zis uas tau muaj nyob hauv Meizhou City, Guangdong xeev hnub tim 15.
Nws yog to taub tias weathered crust homtsawg ntiaj tebminerals yog ib qho chaw tshwj xeeb hauv Suav teb.Cov teeb meem nyob rau hauv ecological ib puag ncig, kev siv peev txheej efficiency, leaching voj voog, thiab lwm yam ntawm cov feem ntau siv ammonium ntsev nyob rau hauv-situ leaching technology tam sim no txwv tsis pub siv thiab ntsuab ntawm tsawg ntiaj teb cov kev pab nyob rau hauv Tuam Tshoj.
Nyob rau hauv teb rau cov teeb meem cuam tshuam, He Hongping pab neeg los ntawm Suav Academy ntawm Sciences Guangzhou lub koom haum Geochemistry tau tsim hluav taws xob tsav mining tshuab rau weathered crust hom tsawg lub ntiaj teb ores raws li kev tshawb fawb txog qhov tshwm sim ntawm lub ntiaj teb tsis tshua muaj nyob rau hauv weathered crust hom rare ntiaj teb ores. .Simulation thwmsim, amplification thwmsim, thiab teb ua qauv qhia pom tau hais tias piv rau cov mining txheej txheem uas twb muaj lawm, hluav taws xob tsav mining tshuab rau weathered crust hom tsawg ntiaj teb ore tau zoo optimized tsawg lub ntiaj teb rov qab npaum li cas, leaching tus neeg saib xyuas ntau npaum, mining voj voog, thiab impurity tshem tawm, ua. nws yog ib qho zoo thiab ntsuab tshiab technology rau weathered crust hom tsawg lub ntiaj teb ore mining.
Cov txiaj ntsig tseem ceeb tau luam tawm hauv 11 cov ntawv qib siab hauv cov ntawv xov xwm xws li "Nature Sustainability", thiab 7 tau txais kev tso cai tsim khoom patents.Ib txoj haujlwm ua qauv qhia nrog qhov ntsuas ntawm 5000 tons ntawm av ua haujlwm tau tsim.Pab neeg tshawb fawb tau hais tias nws yuav ua kom cov kev txhim kho ntawm kev sib koom ua ke thev naus laus zis thiab ua kom cov kev lag luam ua tiav ntawm kev ua tiav.
Lub rooj sib tham kev soj ntsuam kev tshawb fawb thiab thev naus laus zis saum toj no yuav tuaj koom los ntawm cov kws tshaj lij thiab cov kws paub zoo los ntawm cov tsev kawm qib siab hauv tsev, cov koom haum tshawb fawb, thiab cov lag luam.
