Kuyambira m'zaka za m'ma 1990, mayiko akunja ayamba kuphunzira luso lanzeru lothandizira anthu ndipo apanga zowunikira, monga GunsonSortex ku UK ndi Outo-kumpu ku Finland.ndi RTZOreSorters, ndi zina zotero, apanga ndi kupanga mitundu yoposa khumi ya ma photoelectric sorters, ma radioactive sorters, etc., ndipo akhala akugwiritsidwa ntchito bwino posankha zitsulo zopanda chitsulo ndi zitsulo zamtengo wapatali, koma chifukwa cha mtengo wapamwamba, otsika kusanja molondola, The processing mphamvu ndi yaing'ono, ndipo ndi malire Kukwezeleza ndi ntchito.
Poyerekeza ndi mayiko akunja, kafukufuku waukadaulo wokhudzana ndiukadaulo m'dziko langa adayamba mochedwa, ndipo gawo lofufuzira ndi lopapatiza.Cha m'ma 2000, makina ena osankhira adawonekeranso pamsika wapakhomo, makamaka kusankha mitundu, kusanja kwa infuraredi, kusanja magetsi, ndi zina zambiri. makamaka ntchito kusanja tirigu, chakudya, tiyi, mankhwala, mankhwala zopangira, pepala, galasi, Zinyalala kusanja ndi mafakitale ena, koma zamtengo wapatali ndi osowa zitsulo monga golide, osowa nthaka, mkuwa, tungsten, malasha, ofooka maginito chitsulo ore, etc. sangakhale mogwira chisanadze osankhidwa ndi kutayidwa pasadakhale, makamaka mu youma wanzeru chisanadze kusankha mchira kuponya zida akadali akusowekapo.
Pakali pano, migodi zoweta alibe ogwira zida zapadera kwa chisanadze kutaya refractory ofooka maginito ores, sanali ferrous zitsulo ores, etc., makamaka kudalira choyambirira Buku kusanja njira ndi maginito kupatukana njira, ndi kusanja tinthu kukula zambiri. 20 mpaka 150 mm.Mphamvu zapamwamba komanso mtengo wokwera.Kwa mchere wosiyana pang'ono mu maonekedwe, kuwala, mawonekedwe, ndi kachulukidwe ka miyala ya ore ndi zinyalala, kusanja bwino kumakhala kochepa, cholakwika ndi chachikulu, ndipo ena sangathe kusiyanitsa.Kwa magnetite, njira yolekanitsa maginito ingagwiritsidwe ntchito kuponya michira, koma kwa ores omwe ali ndi mphamvu zofooka za maginito, ore zitsulo zopanda chitsulo, ndi zina zotero, cholakwika cholekanitsa ndi chachikulu, kupatukana kwachangu kumakhala kochepa, ndipo pali kuwonongeka kwakukulu kwa chuma. .
Makina osankhidwa anzeru a sensa ndi oyenera kuyikapo kale ore ndi kuchuluka kwa dilution yaiwisi yaiwisi komanso kulekanitsa kwabwino pakati pa miyala yozungulira ndi miyala yothandiza pambuyo pophwanya.
01
Kutsitsa gawo lodulidwa la migodi kuli kofanana ndi kukulitsa nkhokwe zamafakitale;
02
Kuchepetsa mtengo wakupera ndi kupindula kotsatira;
03
Mphamvu yogwiritsira ntchito dongosololi ikhoza kukonzedwa bwino ngati zida zoyamba zogaya sizisintha;
04
Kupititsa patsogolo kalasi yomwe yasankhidwa kumathandizira kukhazikika ndi kuwongolera kukhazikika kwazinthu komanso kuchepetsa ndalama zosungunulira;
05
Chepetsani kuchuluka kwa michira yabwino, chepetsani mtengo wopangira ndi kukonza madziwe a ma tailings, ndikuwongolera chitetezo chozungulira malo osungiramo madzi.
Tengani migodi ya golide mwachitsanzo: pakali pano, chuma cha golide cha dziko langa ndi matani 15,000-20,000, omwe ali pachisanu ndi chiwiri padziko lonse lapansi, ndi golide wapachaka woposa matani 360, nkhokwe zagolide za miyala zomwe zimakhala pafupifupi 60%, ndipo pafupifupi. ore deposit grade pafupifupi 5%.Pafupifupi g/t, malo osungiramo miyala ya golide wa miyala ndi pafupifupi matani 3 biliyoni.Lakhala lalikulu kwambiri padziko lonse lapansi wopanga golide.Komabe, njira yopezera golide m'dziko langa imatengerabe njira yachikhalidwe ya flotation-concentrate cyanidation.Palibe njira yabwino yoponyera michira musanaiphwanye ndi kupera.Ntchito yophwanya, kugaya ndi kuyandama ndi yayikulu, ndipo mtengo wopindula udakali wokwera.Kuwonongeka kwa migodi ndi kupitirira 5%, kubwezeretsedwa kwa kupindula ndi kusungunula kuli pafupifupi 90%, mtengo wopindula ndi wokwera kwambiri, chiwongoladzanja chobwezeretsa chuma ndi chochepa, ndipo chitetezo cha chilengedwe ndi chochepa.
Pambuyo kutayidwa ndi kusanja kwanzeru kachipangizo, mwala wosankhidwayo ukhoza kuwerengera 50-80% ya ore yaiwisi yosankhidwa, kupititsa patsogolo golide wosankhidwa ndi 3-5 nthawi, ndikuchepetsa chiwerengero cha ogwira ntchito m'nyumba yovala ndi 15. -20% , 25-30% kuwonjezeka mwala wotayidwa zinyalala ndi 10-15% mu kupanga zitsulo.
Mtengo wophwanyira ndikupera ukhoza kupulumutsidwa ndi zoposa 50%, voliyumu yotsatizana yamankhwala imatha kuchepetsedwa ndi 50%, kupanga bwino kumakula bwino, kugwiritsa ntchitonso miyala ya zinyalala kumakhala bwino, kuwonongeka kwa chilengedwe kumachepetsedwa. , ndipo phindu lachuma likuyenda bwino kwambiri.
Kukula kwa tinthu tating'ono tating'ono tating'onoting'ono tanzeru kumatha kufika pafupifupi 1mm mpaka 300mm, ndipo sensa imatha kuzindikira zidutswa 40,000 za ore pamphindikati.Zimangotengera ma ms ochepa pachidutswa chilichonse cha ore kuchokera pakuzindikirika kwa sensa yolandila kupita ku malangizo osankhidwa omwe amapezedwa ndi woyendetsa.Zimangotengera ma ms ochepa kuti gawo la jakisoni limalize kupha kumodzi.Kuthekera kwakukulu kwa makina amodzi kumatha kufika 400 t / h, ndipo mphamvu yopangira zida imodzi imatha kufika matani 3 miliyoni pachaka, zomwe ndi zofanana ndi mgodi wapakati ndi waukulu.
Zida zanzeru zosinthira sensa zimatha kusintha mapulogalamu ndikusintha malo okonzeratu pa intaneti, ndikuyankha kusinthasintha kwamtundu ndi kuchuluka kwa miyala yaiwisi munthawi yake, zomwe sizingakwaniritsidwe pazida zosankhira zachikhalidwe.Bola ngati miyala yaiwisi ikufika pamlingo wina wosweka mu siteji yophwanyidwa, ngakhale ndi disociation digiri ya ozungulira thanthwe kapena gangue, kapena maganizo omaliza amapangidwa mwachindunji, izo makamaka ntchito zitsulo zosiyanasiyana ores (osati maginito kapena ofooka maginito chitsulo ore, mkuwa, kutsogolera, Kusankhiratu ndi kutaya zinyalala za zinki, faifi tambala, tungsten, molybdenum, malata, osowa nthaka, golide, etc.), malasha ndi sanali zitsulo mchere monga talc, fluorite, calcium carbonate, dolomite, calcite, apatite, etc. kuchuluka kwa coarse kuganizira kulowa mu ndondomeko wotsatira yafupika kwambiri, ndipo kalasi ndi bwino, amene angachepetse kwambiri mtengo wa wotsatira akupera ndi beneficiation.Intelligent sensa beneficiation ndi wosayerekezeka ndi mwambokusankhiratu pamanja, kupatukana kwa maginito, ndi kupatukana kwazithunzi malinga ndi kulondola kwachizindikiritso, liwiro loyankhira, kusanja bwino, komanso mphamvu yosinthira.Kusankha mwanzeru ndikuwonetsetsa kwathunthu kwaukadaulo wamakono wozindikira komanso ukadaulo wapa digito, ndipo kwakhala njira yayikulu yachitukuko pakusankhiratu mchere.
Zinthu zamchere zaku China zimakhala zowonda kwambiri, ndipo mphamvu yosungiramo ndi yayikulu.Momwe mungatayire zinyalala pasadakhale, kupititsa patsogolo luso la kugaya ndi kupindula kotsatira, ndi kuchepetsa mtengo wopezera phindu, ndikuchitapo kanthu mwachangu ku zofunikira zonse za dziko za “kumanga migodi mwanzeru ndi migodi yobiriwira”. chitukuko cha migodi ya dziko langa.Choncho, chitukuko cha zida zanzeru zosankhira zoyenera mchere wam'nyumba zayandikira, ndipo chiyembekezo cha msika chidzakhala chotakata kwambiri.
