Pambuyo pakugwiritsa ntchito othandizira mchere: Pakusintha kwa mawu, zotsatira za kuchuluka kwa mchere wa mchere umatchedwa kuyambitsa. Wothandizirayo ankakonda kusintha kapangidwe ka mchere ndikulimbikitsa kulumikizana pakati pa otolayo ndipo mcherewo umatchedwa wogwira ntchito.
Kuyambitsa kumatha kugawidwa mu: 1. Kuyambitsa kosatha; 2. Chitsanzo; 3. Kuuka kwa akufa; 4. Vulcananiza.
1. Kuyambitsa kwakanthawi
Mukamakonza polymettic ores, mcherewo umakhala ndi ma ayoble ena osungunuka mchere pogaya. Mwachitsanzo, pamene Ssuleraite ndi zamkuwa zamiyala yamkumpizi, zochepa za mchere wamtundu wa mkuwa umakhala oxidized mu sulfate ya mkuwa pambuyo pa ored. The Cu2 + ma ayoni a clurry omwe ali ndi Spaulerinc kuti ayambitse, kupangitsa kuti zikhale zovuta kupatuka mkuwa ndi zinc. Ndikofunikira kuwonjezera ntchito zina monga laimu kapena sodium carbonate yapamwamba, komanso zina zopanda pake zomwe zingayambitse kutsegula.
Chachiwiri, Preactation
Kusankha mchere, onjezerani woyambitsa kuti ayambitse. Pamene Gorite ali ndi maxidid osakaniza, acid a acid amawonjezeredwa kuti asungunuke filimu ya oxide pamwamba pa pyrite asanatulutse, ndikuwonetsa pamwamba, zomwe ndizopindulitsa kuzichita.
atatu.recover
Amanena za mchere wambiri womwe waletsa, monga Stehalerite zomwe zapezedwa ndi cyanide, ndipo zitha kuukitsidwa powonjezera kuchuluka kwa mkuwa.
Zinayi.Vulcanation
Zimangotanthauza kuchiritsa zitsulo za oxide ndi sodium sulfide kuti apange mchere wa sulufule wa sulufuul o kwa oxide, kenako ndikukongoletsa ndi xanthate.
Makina amchere ogwiritsira ntchito ngati oyendetsa ndi:
Sulfurous acid, sulufurous acid, sodium sulfide, mkuwa wamkuwa, kusungunuka dambo, sodium hydroxide, barboride mchere, etc.
