Khadka Wax-soo-saarka Wax-soo-saarka Macdanta Naxaasta ah ee Wax-tarka leh
Khadka Waxsoosaarka Wax-soosaarka Naxaasta ah ee Wax-ku-oolka ah ee Burburinaya: Habaynta La Habeeyay, Isticmaalka Tamarta Hoose, Ku Habboon ee Godka Furan/Miinooyinka Dhulka Hoostiisa
Khadkayaga wax-soo-saarka macdanta naxaasta ah ee la habeeyey waxaa si gaar ah loogu talagalay in lagu farsameeyo macdanta naxaasta ah ee adkaanta kala duwan (Mohs hardness 3-7) iyo cabbirrada walxaha cayriin (≤1500 mm), oo ay ku jiraan macdanta copper sulfide, macdanta naxaasta oksaydhka iyo macdanta naxaasta isku dhafan. Sida isku xidhka udub dhexaadka u ah ka faa'iidaysiga macdanta naxaasta ee xiga (sida sabbaynta iyo leaching), khadka wax soo saarku wuxuu isku daraa burburinta marxaladaha badan, baadhista saxda ah iyo nidaamyada gudbinta walxaha deggan, kaas oo loo habeyn karo iyadoo loo eegayo awoodda mashruuca, astaamaha macdanta iyo cabbirka walxaha alaabada la beegsaday (sida caadiga ah 10-20 mm diyaarinta shiidi).
Aasaaska Naqshadaynta Core
Xuddunta khadka wax-soo-saarka waxay ku jirtaa heerka sare ee is-beddelka, kaas oo daboolaya faahfaahin kasta oo laga soo bilaabo xulashada alaabta qalabka ilaa qaabka goobta. Waxay si dabacsan ula qabsan kartaa baahiyaha gaarka ah ee mashaariicda kala duwan: alaabta ceeriin ee leh maadada dhoobada sare leh, mashiinka ciidda giraangiraha (XSD 2610) ayaa lagu dari karaa; mashaariicda leh goobo cidhiidhi ah, "qaabaynta saddex-geesoodka ah ee 3D" ayaa loo qaabeyn karaa si loo badbaadiyo booska. Dhanka kale, khadka ayaa si heer sare ah ula qabsanaya miinooyinka furan iyo dhulka hoostiisa labadaba, sidoo kale wuxuu farsameyn karaa macdanta kale ee adag (sida magnetite, hematite iyo manganese) iyadoo la hagaajinayo cabbirada qalabka iyadoo loo eegayo qallafsanaanta macdanta iyo shuruudaha cabbirka walxaha.
Habaynta Qalabka La Habeeyay (Qaybaha Muhiimka ah)
Khadka wax-soo-saarka wuxuu ka kooban yahay shan qaybood oo asaasiga ah, mid kastaa wuxuu ku qalabaysan yahay qalab gaar ah iyo cabbirro si loo hubiyo hawlo hufan oo deggan. Qaybta jajabinta macdanta cayriin ee ceyriinka ah, burburiyaha daanka culus ayaa la qaataa, oo leh karti wax-qabad oo ah 50-1200 tan saacaddii (TPH), cabbirka furitaanka quudinta 600 × 900 mm (la-habooneyn karo), kala duwanaanshaha furitaanka furitaanka dareeraha ee 10-350 mm, iyo walxo bir ah oo birta manganese sare leh si loo waafajiyo adkaanta sare.
Qeybta labaad ee jajabinta, jajabiyaha korantada caadiga ah ayaa loo isticmaalaa, oo leh awoodda wax qabad ee 30-800 TPH, kala duwanaanshaha furitaanka furitaanka ee 5-50 mm, nooca daloolka caadiga ah ee ku habboon macdanta dhexdhexaadka ah iyo kuwa adag, iyo nidaamka xakamaynta hagaajinta hawo-mareenka si toos ah. Qaybta jajabinta ganaaxa waxay ku qalabaysan tahay burburiyaha korantada madaxa-gaaban, oo leh karti wax-qabad oo ah 20-600 TPH, kala duwanaanshaha furitaanka furitaanka ee 3-30 mm, nooca daloolka gaaban ee madaxa-gaaban ee alaabada gogosha ah, iyo nidaamka xakamaynta hagaajinta hawo-qaadista ee ilaalinta culeyska tooska ah.
Qaybta baadhista iyo kala-soocidda, shaashad gariir wareeg ah ayaa la qaatay, kaas oo u dhigma awoodda wax-soo-saarka ee 20-600 TPH, oo leh cabbirka mesh-ka ee 10-20 mm (la beddeli karo), hufnaanta baadhista ee ≥95%, iyo 1-2 lakabyo shaashad ah si loo daboolo baahiyaha kala-soocidda. Qaybta gudbinta kaalmaynta waxa ka mid ah feedhiyeyaasha gariiraya iyo kuwa suunka qaada: feedhaha gariirku waxa uu leeyahay awood quudin ah 50-1200 TPH, lebis quudinta ≤±5%, mugga hopper ee 1-5 m³ (oo ku salaysan xaaladaha shaqada goobta), iyo electromagnetic/gariiraya hab wadista motor; Gaadhida suunka ayaa leh awood gudbineed oo ah 50-1200 TPH, ballac suunka ah 800-1600 mm, xawaaraha gudbinta ee 1.2-2.0 m/s, iyo walxo jir ah oo ah birta kaarboon/ birta aan fiicnayn si ay ula qabsato deegaanka daxalka ah.
Faa'iidooyinka Muhiimka ah
Kalsoonida sare iyo xasiloonida aadka u fiican ayaa ah faa'iidooyinka asaasiga ah ee khadka soo saarista macdanta naxaasta. Qaybaheeda muhiimka ah, sida burburinta daanka culayska culus leh, mishiinnada kootada iyo muraayadaha gariiraya ee xidha-xidhka u adkaysta, waxay ka samaysan yihiin walxo waara (tusaale, birta manganese sare ee xadhkaha burburinta), kuwaas oo u adkeysan kara saamaynta macdan adag ee naxaasta ah. Nidaamka xakamaynta isku dhafan wuxuu ku qalabaysan yahay cillad is-aqoonsiyeedka, kaas oo wakhtiga dhabta ah uga digaya hawl-wadeenada dhibaatooyinka iman kara (sida culeyska xad-dhaafka ah iyo kulaylka), yaraynta xiritaanka lama filaan ah. Tani waxay hubinaysaa in khadka wax soo saarka uu si joogto ah u shaqeyn karo muddo dheer, yaraynta wakhtiga dhimista iyo bixinta waxtarka farsamaynta macdanta xasilloon ee miinooyinka ama dhirta macdanta.
Khadku waxa kale oo uu leeyahay awood-soo-saar sare, kharashyo hawleed oo hooseeya iyo ku-dhaqanka ballaadhan. Ku qalabaysan dalool burbursan oo la hagaajiyay iyo matoor-wareeg-sare ah, awooddeeda wax-qabadku waxay gaari kartaa 50-1000 TPH, si fududna u buuxinaysa baahiyaha sahayda macdanta baaxadda leh ee dhirta birta ama dhirta ka faa'iidaysta. Naqshadeynta tamarta-badbaadinta ee burburiyaha iyo mareenada ayaa hoos u dhigaya isticmaalka tamarta 10-15% marka loo eego khadadka wax soo saarka dhaqameed. Intaa waxaa dheer, xidhashada qaybo ka mid ah (sida taarikada daanka iyo shaashadaha) waxay leeyihiin nolol adeeg oo dheer, yaraynta soo noqnoqda beddelka waxayna si weyn hoos u dhigtaa dayactirka iyo kharashka alaabta.
Waxaa intaa dheer, line-soo-saarka waxay hubisaa in size qayb alaabta labis, qaabka qayb wanaagsan iyo heerka macdanta hoose ganaax. Qaadashada burburinta marxalado badan iyo habka baaritaanka (burburin daanka ee burburin aan dhab ahayn + burburiyaha koorta ee burburinta dhexdhexaadka ah iyo ganaaxa + shaashad gariir heersare ah oo loogu talagalay baarista ganaaxa), waxay dammaanad qaadaysaa cabbirka qayb ka mid ah alaabta. Mabda'a burburinta kolayga ee burburiyaha koorta wuxuu yareeyaa burburinta xad-dhaafka ah, taasoo keentay qaabka walxaha alaabta wanaagsan (inta badan qaybaha cubic), si kor loogu qaado waxtarka hababka ka-faa'iidaysiga ee xiga (sida kala-soocidda magnetic iyo sabbeynta). Isla mar ahaantaana, naqshadaynta baadhista wareegga-xiran waxay dib u warshadaynaysaa agabka baaxadda weyn ee dib-u-burburinta, yaraynta wax-soo-saarka budada wanaagsan (badanaa wax ka yar 5%), ka fogaanshaha qashinka walxaha iyo sii wanaajinta qiimaha dhaqaale ee alaabta ugu dambeysa ee macdanta.
