Ukusetyenziswa kweSodium Hexametaphosphate kwiMineral Flotation

intshayelelo

I-mineral flotation yindlela esetyenziswa ngokubanzi kwishishini lemigodi ukohlula izimbiwa ezixabisekileyo kwiminerali ye-ganggue. Ixhomekeke kumahluko kwiipropathi ezibonakalayo kunye neekhemikhali zemiphezulu yezimbiwa. I-sodium hexametaphosphate, kunye nesakhiwo sayo esisodwa sekhemikhali kunye neempawu, ifumene izicelo ezibalulekileyo Ukudada kwezimbiwa iinkqubo. Eli nqaku lijonge kwiinkalo ezahlukeneyo zokusetyenziswa kwi-mineral flotation.

Iipropati zeSodium Hexametaphosphate

I-sodium hexametaphosphate yi-inorganic polymer compound. Kubonakala ngathi yikristale ecacileyo engenambala okanye umgubo omhlophe. Inyibilika kakhulu emanzini, kwaye isisombululo sayo samanzi si-alkaline. Emoyeni, inomlinganiselo othile we-hygroscopicity. Ezi zakhiwo zomzimba kunye neekhemikhali zibeka isiseko sokusebenza kwayo kwi-mineral flotation.

Iindima kwiMineral Flotation

Uxinzelelo

1.Ukuvinjelwa kweSilicate kunye neCarbonate Minerals

• I-sodium hexametaphosphate iyasebenza ekunqandeni i-quartz kunye neeminerali ze-silicate. Kwi-flotation yezinye ii-ores, ezifana nezo ziqulethe i-feldspar kunye ne-mica, inokubhengeza kumphezulu wale minerali ye-silicate. Ngokomzekelo, kwi-flotation ye-zirconium ores, inokunciphisa ukujikeleza kwe-feldspar edibeneyo kunye nezinye iiminerali ze-silicate gangue ngokubhengeza kwiindawo zabo.

• Ikwabonisa iziphumo zokuthintela kwiiminerali ze-carbonate ezifana ne-calcite kunye ne-limestone. Kwindawo edadayo yephosphate ores apho icalcite iyiminerali eqhelekileyo, Isodiyam hexametaphosphate inokusabela nge-calcium ion kumphezulu we-calcite. Yenza iikhompawundi ezizinzileyo ezandisa i-hydrophilicity ye-calcite surface, okwenza kube lula ukuba ifakwe ngumqokeleli, ngaloo ndlela ifezekise injongo yokuthintela.

2.I-Inhibition Mechanism

• Enye yeendlela eziphambili zokuthintela zihambelana nokusabela kwayo kunye neeoni zetsimbi kumphezulu wamaminerali. Xa kuziwa kwiiminerali eziqulethe i-ion zetsimbi ezininzi ze-valent, i-sodium hexametaphosphate inokwenza iikhompawundi ezizinzileyo kunye nezi ion zetsimbi. Kwi-nickel ore flotation, isabela kunye neeyoni ezithile kumphezulu wenyoka, ezinqanda ukuphaphatheka kwenyoka.

• Ukongeza, kwisisombululo samanzi, i-sodium hexametaphosphate inokwenza ionize. Iyakwazi ukusabela nge-calcium ions kwi-mineral surface kunye nesigaba solwelo. Ekwahlukaneni kwe-calcite kunye ne-cassiterite, i-compound eyenziwe kwi-calcite surface ayichaphazeli nje kuphela i-calcite kodwa inokuthi ibhengeze kwindawo ye-cassiterite, ukunciphisa ukukhethwa kokuthintela kunye nokunciphisa i-adsorption yomqokeleli kwindawo yamaminerali.

Ukuchithachitha

1.Ukusasazwa kweMineral Pulp

• Kwiinkqubo zokudada, ngakumbi kwezinye ii-ores ezineeminerali ezicolekileyo okanye ezinodaka oluphezulu, ukusasazwa kwepulp yezimbiwa kubalulekile. I-sodium hexametaphosphate inokudlala indima ebalulekileyo njenge-dispersant. Ngokomzekelo, kwi-flotation ye-nickel - i-pyrite ores ehambelana nenyoka, ukongeza inani elifanelekileyo le-sodium hexametaphosphate inokusasaza i-pulp flotation. Oku kungenxa yokuba kunciphisa ukugqunywa kwenyoka kumphezulu we-nickel - i-pyrite, enenzuzo ekubuyiseleni i-flotation ye-nickel - i-pyrite.

2.Inkqubo yokusasaza

• Isodium hexametaphosphate inokuthoba isakhono somphezulu weeminerali. Ngenxa yoko, i-electrostatic repulsive force phakathi kwamasuntswana amaminerali ayanda. Isakhiwo sayo se-molecular, i-polymer compound ehambelanayo kunye nobude bekhonkco ubuncinane be-20 - i-100 units, xa i-adsorbed kwi-mineral surface, inokunyusa impembelelo yokuthintela i-steric phakathi kwamasuntswana. Kwi-flotation ye-phosphate ores ecolekileyo, le mpembelelo yokusabalalisa inokuthintela ukuhlanganiswa kwe-phosphate kunye neeminerali ze-ganggue, ukuphucula ukusebenza kakuhle kokwahlula.

Ukusetyenziswa kweMineral Flotation eyahlukeneyo

I-Phosphate Ore Flotation

1.Ukwahlula okukhethiweyo

• Kwi-phosphate ore flotation, i-sodium hexametaphosphate isoloko isetyenziselwa ukwahlula iiminerali ze-phosphate kwiiminerali ze-ganggue. I-Phosphate ores ihlala idityaniswa neeminerali ezahlukeneyo ze-ganggue ezifana ne-calcite, i-dolomite, kunye neeminerali ze-silicate. I-sodium hexametaphosphate inokunqanda ngokukhetha ezi minerali ze gangue. Kwinkqubo yokujikeleza ejikelezayo kwezinye ii-ore ze-phosphate, ukongeza inani elincinci le-sodium hexametaphosphate kunokunyusa ngokufanelekileyo ibakala kunye nokubuyiswa kwe-phosphate concentrate. Inokusabela ngeeminerali ezingezizo ze-phosphate ngaphandle kokusabela kunye neeminerali ze-phosphate, ngaloo ndlela iphucula ukukhethwa kwe-phosphate mineral flotation.

2.Impembelelo kwi-Foam Stability

• Ikwanayo nefuthe kuzinzo logwebu kwi-phosphate ore flotation. Ugwebu kwinkqubo yokuntanta ludlala indima ekuqokeleleni izimbiwa zephosphate. I-sodium hexametaphosphate inokomeleza ukuzinza kogwebu. Iyakwazi ukuvelisa inani elikhulu le-foams ezinzile, ezinceda ukuphucula umphumo wokuqokelela i-phosphate minerals. Iiminerali ze-phosphate zinokuthwalwa ngcono yi-foam ezinzileyo ukuya kumphezulu, ngaloo ndlela iphucula ukusebenza kakuhle kwe-flotation kunye nebakala.

Non-Flotation Metal Ore Flotation

1.Nickel Ore Flotation

• Njengoko bekutshiwo ngaphambili, kwi-nickel ore flotation, i-sodium hexametaphosphate isetyenziswa ikakhulu ukuthintela inyoka. I-Serpentine yiminerali ye-ganggue eqhelekileyo kwi-nickel ores, kwaye ubukho bayo bunokuchaphazela ukujikeleza kwe-nickel-ethwele iiminerali. Ngokudibanisa i-sodium hexametaphosphate, inokusabela nge-ion zetsimbi kumphezulu wenyoka, ukunciphisa ukudada kwayo kunye nokuphucula ukuhlukana kwe-nickel-ethwele iiminerali ezivela kwinyoka. Oku kunenzuzo ekuphuculeni ibakala kunye nokubuyiswa kwe-nickel concentrates.

2.Ubhedu kunye neLead-Zinc Ore Flotation

• Kwi-copper kunye nelothe - i-zinc ore flotation, xa kukho i-calcium eyayanyaniswayo - equlethe iiminerali ze-ganggue ezifana ne-calcite kunye ne-dolomite, i-sodium hexametaphosphate ingasetyenziselwa ukunqanda ezi minerali ze-ganggue. Kwezinye ubhedu ezintsonkothileyo - lead - zinc ores, ukulungelelanisa isixa sodium hexametaphosphate unako ukulawula ngempumelelo ukudada amaminerali gangue, ekuphuculeni selectivity of flotation kunye nomgangatho ubhedu, ilothe, kwaye zinc igxile.

Imiba echaphazela isiphumo sesicelo

Isistim

1.Ukumiselwa kweSithamo esiLungileyo

• I-dosage ye-sodium hexametaphosphate inempembelelo enkulu ekusebenzeni kwayo kwi-mineral flotation. Idosi engafanelekanga inokukhokelela kwiziphumo ezingancumisiyo. Ukuba idosi iphantsi kakhulu, ayinakunqanda ngokufanelekileyo iiminerali ze-ganggue okanye isasaze ipulp. Ngokomzekelo, kwi-flotation ye-phosphate ore, ukuba isixa se-sodium hexametaphosphate eyongeziweyo asanelanga, i-minerals ye-ganggue ayinakuvinjelwa kakuhle, okukhokelela kwibakala eliphantsi lokugxila kwe-phosphate.

• Ngakolunye uhlangothi, ukuba idosi iphezulu kakhulu, ayinako ukunyusa iindleko kuphela kodwa ibangele nemiphumo emibi. Kwezinye iimeko, i-sodium hexametaphosphate egqithisileyo inokuthintela iiminerali ekujoliswe kuzo kwinqanaba elithile, ukunciphisa izinga lokubuyisela. Ke ngoko, ukumisela elona thamo lifanelekileyo ngophando lovavanyo kunye nokulungiswa kwendawo kubalulekile ekufezekiseni ezona ziphumo zintle zokudada.

pH Ixabiso lePulp

2.Impembelelo kwiiNjongo zeMichiza

• Ixabiso le-pH le-pulp ye-flotation lichaphazela ukuphendula kweekhemikhali ze-sodium hexametaphosphate. Kwiindawo ezahlukeneyo ze-pH, i-ionization degree kunye ne-chemical form ye-sodium hexametaphosphate inokutshintsha. Kwimeko-bume ene-asidi, umphumo wayo wokuthintela kwezinye iiminerali unokuba buthathaka. Kwindawo ene-alkaline eninzi, inokusabelana nezinye izinto kwipulp, echaphazela umsebenzi wayo wesiqhelo. Ngokomzekelo, kwi-flotation yobhedu oluthile - i-lead - ores ye-zinc, ukugcina ixabiso le-pH elifanelekileyo (ngokuqhelekileyo lijikeleze i-8 - 10) linokuqinisekisa ukuba i-hexametaphosphate ye-sodium ithintela ngokufanelekileyo iiminerali ze-ganggue kwaye ikhuthaze ukujikeleza kweeminerali ezijoliswe kuyo.

isiphelo

I-sodium hexametaphosphate idlala iindima ezininzi ezibalulekileyo kwi-flotation yezimbiwa, kubandakanywa njenge Uxinzelelo kunye nomsasazi. Ukusetyenziswa kwayo kwiindidi ezahlukeneyo ze-mineral flotation, ezifana ne-phosphate ore kunye ne-non-ferrous metal ore flotation, iphucule kakhulu ukusebenza kakuhle kunye nomgangatho wokwahlula izimbiwa. Nangona kunjalo, ukusebenzisa ngokupheleleyo amandla ayo, izinto ezinje ngedosi kunye ne-pulp pH kufuneka zilawulwe ngononophelo. Ngophuhliso oluqhubekayo loshishino lwezimayini, uphando olongezelelweyo malunga nokusetyenziswa kwe-sodium hexametaphosphate kwi-flotation yezimbiwa kunokukhokelela kwiindlela ezisebenzayo nezizinzileyo zokusetyenzwa kwezimbiwa.
