Ungalithola kuphi igolide? ukuhlaziywa enemininingwane

Kusukela sihloko, uzofunda ukuthi ithole legolide, yini ukubaluleka kwalo, iziphi izinhlobo ukukhiqizwa futhi lapho metal isetshenziswa.

I Endulo

With esinjalo metal ezihloniphekayo, efana negolide, isintu kuba ezijwayele izinkulungwane eziningi zeminyaka. Njengoba izinto sekusebenta lisetjentiswe ngenxa amandla adonsela phansi yayo okusezingeni eliphezulu ethize kanye umsungulo isihlobo, kodwa ngokushesha yathola ukusetshenziswa njengendlela material for ubucwebe kanye okulingana ejwayelekile zokwenana - imali. Lokhu kungenxa yokuthi igolide - omunye izinto eziyivelakancane. Ngaphezu kwalokho, lokho akusho oxidize emoyeni futhi emanzini. Kodwa kuyafaneleka kwakusho ukuthi kwakuzoba nezikhathi lapho yensimbi ezivamile zenani ephakeme ukwedlula metal zasebukhosini. Nokho, wahlala isikhathi eside: ngaphambi kwesikhathi lapho ngafunda kukhishwe insimbi ancibilike ngezinga elikhulu. Ngakho, lapho ukuthola igolide?

ukusabalala

Lokhu metal itholakala cishe kuwo wonke amazwekazi izinto eziningi ezahlukene, kodwa hhayi yonke imikhakha yayo misela kokuthutha ngenxa yezizathu zezomnotho. Uma sithatha ngenxa kwesikhathi sokukhokha ngo-2014, emazweni ngobukhulu-getters babe China, Australia neRussia. I-United States ilandelwe yi-Canada ne South Africa. Kodwa lapho ongazithola igolide ezweni lethu?

Isizinda of metal ezingavamile ukuba phakathi XVII ekhulwini uMbuso Russian awuzange kwenziwe, futhi zonke amasheya ekhona babe umphumela ukuhweba nge amazwe aseNtshonalanga. Kodwa ngo-1745 sekushintsha konke. ongumlimi Ural Erofei Markov Uthole isigaxa segolide eduze komfula, futhi njengoba kubika iziphathimandla eYekaterinburg.

Manje endaweni engakhulela Berezovsky edolobheni, lapho kukhona omunye Amasimu endala namuhla.

Njengoba umongo walo ingatholakala eSiberia, Yakutia, naseMpumalanga Ekude. Ingots lokhu metal kukhona ongowenani elikhulu njengoba zigcine igolide yezwe, ngoba yenziwa imihlobiso, imali yamaphepha esiyisikhumbuzo futhi lisetshenziswe eyinkimbinkimbi electronics, chemistry isikhala umkhakha. Kodwa lapho ongazithola igolide ngaphezulu?

amanzi

Omunye wemibuzo izingane ezivame kakhulu sika kungani uLwandle Lukasawoti, futhi emfuleni lapho? Into wukuthi labo emifuleni efanayo agelezele olwandle, phezu emhlabathini waso wageza kusukela nosawoti ahlukahlukene namanye amakhemikhali. Ngokwesibonelo, emanzini yoLwandle Olumnyama siqukethe iningi ishadi lesikhathi, kodwa ngemithamo emincane kakhulu. Ingabe kukhona igolide, mayelana 5 amakhilogremu ngalinye km cubic uketshezi.

ezimayini

Manje zonke izimayini esetshenziswa imishini ekhethekile, okuyinto ngezinye izikhathi kwandisa amandla okukhiqiza. Kodwa indlela classical, ngalo bonke baqala - kwathiwa ngesandla ukugeza inhlabathi, ngenxa okuyinto yabavukuzi wathola isihlabathi segolide. Iqiniso lokuthi ezifakwa enkulu nge nxa udinga amatshe amakhulu ezingajwayelekile kakhulu, futhi ngokuvamile ibe igolide lemvelo libukeka okusanhlamvu encane, okufanele kube ngokucophelela futhi zakhipha uhlukane ngenalusizo dwala.

Phela, leli qiniso ezithakazelisayo: the jeans zakudala namaqhosha phezu emaphaketheni yasungulwa eMelika ngesikhathi "ligolide". umthungi Abembi bakhononda ngokuthi ngenxa isisindo esikhulu zemali equkethe uthuli igolide, emaphaketheni ngokuvamile zidabukile.

isizinda

Izindlela eyinhloko ezimayini zegolide - wokuwasha, ingxube kanye inqubo yamakhemikhali. Kodwa izinto zokuqala kuqala

Kusukela ezikhathini zasendulo asetshenziswa nini ngokokuqala ngqá, njengoba iningi elula futhi akudingi imishini eyinkimbinkimbi. Ngokuvamile, ezimayini kwahlelwa emifuleni noma ezinye machibi. izindlela Sense ukuqoqa amatshe, bese wageza zahlolwa. Ukungcola, udoti kanye engenamsebenzi idwala eluent negolide, ngenxa amandla adonsela phansi yayo enkulu ethize, wahlala emathileyi. Indlela esetshenziswa manje, kodwa ngezinga ezimbonini.

Okwesibili - ingxube - zaziwazi kahle abantu kusukela ezikhathini zasendulo. Le ndlela ukukhiqizwa igolide yasetshenziswa ngokokuqala ngqa eNingizimu Melika. Iqiniso lokuthi leli metal yizicukuthwane kalula ancibilikisa e mercury, futhi uma yokugcina ayahwamuka, le alembic kuyoba ngegolide elihlanzekileyo, nezikhoxe selehlile futhi mercury eqoqwe lingasetshenziswa kabusha.

Neyesithathu indlela cyanidation, kuthi akufane nokwenzeka okungenhla. Kuphela sensimbi hhayi ziyoncibilika le mercury kanye ingxube cyanides acid.

Kungenzeka yini ukuba pan igolide?

Kungenzeka. Lutho kuvimbela umuntu ukuya emajukujukwini ehlathi, kude sibonakale emehlweni abantu, bese ubheka emayini engasasebenzi noma umthambo entsha. Kodwa kufanele sikhumbule ukuthi, ngokuvumelana Criminal Code, isijeziso kubalulekile, kanye ukuhweba ngokungemthetho noma sizama ukuthengisa le metal. Ngakho-ke akuyona kuwufanele ingozi.
