Pambuyo pakugwiritsa ntchito mineral processing activator: Mumayendedwe oyandama, zotsatira zakuwonjezera kusuntha kwa mchere kumatchedwa activation.Wothandizira ntchito kusintha kapangidwe ka mchere pamwamba ndi kulimbikitsa kugwirizana pakati otolera ndi mchere pamwamba amatchedwa activator.
Kutsegula kungathe kugawidwa kukhala: 1. Kutsegula mwachisawawa;2. Preactivation;3. Kuuka kwa akufa;4. Vulcanization.
1. Kutsegula mwachisawawa
Mukakonza ores omwe si a ferrous polymetallic ores, mcherewo umangosinthana ndi ma ion amchere osungunuka panthawi yopera.Mwachitsanzo, pamene mchere wa sphalerite ndi mkuwa wa sulfide umakhalapo, mchere wochepa wa mchere wa sulfide umapangidwa nthawi zonse kukhala copper sulfate pambuyo pa kukumbidwa.Ma ion a Cu2+ mu slurry amachitira ndi sphalerite pamwamba kuti ayambitse, zomwe zimapangitsa kuti zikhale zovuta kusiyanitsa mkuwa ndi zinki.Ndikofunikira kuwonjezera zinthu zina zosinthira monga laimu kapena sodium carbonate kuti ziwonjezeke, komanso "mayoni osapeŵeka" omwe angayambitse kuyambitsa.
Chachiwiri, preactivation
Kuti musankhe mchere, onjezani choyambitsa kuti muyambitse.Pamene pyrite ndi oxidized kwambiri, sulfuric acid amawonjezeredwa kuti asungunuke filimu ya oxide pamwamba pa pyrite isanayambe kuyandama, kuwonetsa malo atsopano, omwe amapindulitsa kuyandama.
atatu.chira
Zimatanthawuza za mchere zomwe zaletsedwa kale, monga sphalerite yomwe yaletsedwa ndi cyanide, ndipo ikhoza kuukitsidwa powonjezera mkuwa wa sulfate.
Zinayi.vulcanization
Amatanthauza choyamba kuchiza chitsulo okusayidi ore ndi sodium sulfide kupanga wosanjikiza zitsulo sulfure mchere filimu pamwamba pa okusayidi ore, ndiyeno flotation ndi xanthate.
Ma mineral processing reagents omwe amagwiritsidwa ntchito ngati activators ndi awa:
Sulphuric acid, sulfurous acid, sodium sulfide, copper sulfate, oxalic acid, laimu, sulfure dioxide, lead nitrate, sodium carbonate, sodium hydroxide, mchere wotsogolera, mchere wa barium, etc.
