Fire Assay akuyona kuphela izindlela elisencwadini yasendulo okucebisayo ngegolide nangesiliva, kodwa futhi kutindlela letibalulekile igolide kanye nokuhlaziywa esiliva. Geology, izimayini, igolide nesiliva smelters ekhaya aphesheya ukuyisebenzisa njengoba enokwethenjelwa kakhulu ukuhlaziya indlela futhi asetshenziswa kabanzi ekukhiqizeni. Amanye amazwe usetha le ndlela njengoba indlela ejwayelekile. Izwe lethu futhi uwubeke njengesizathu indlela kazwelonke ejwayelekile ekutholweni igolide ngegolide ugxilisa, ugxilisa ithusi, ubucwebe igolide and ingxubevange igolide. With ukuthuthukiswa isayensi nobuchwepheshe, zikhona izindlela ezingasho entsha ngoba ukuhlaziya ngegolide nangesiliva, futhi amathuluzi analytical beba more and okuthuthukile. Uma kuqhathaniswa nezinye izindlela, indlela umlilo Assay has a inqubo eside ezisebenza futhi kudinga amakhono athile. Kukhona abahlaziyi abaningi azame ukusebenzisa ezinye izindlela kohlaziyo esikhundleni umlilo assays.

 

Nokho, indlela umlilo Assay kuyinto Irreplaceable. Ekutholweni okuqukethwe igolide e ephezulu okuqukethwe igolide izinto zokusetshenziswa noma ngegolide elihlanzekile, ukunemba kwayo kanye nokunemba ziphansi ezinye izindlela ukuzimisela oqondile. Ekuhlaziyeni ukulamula umbango zegolide nezesiliva okuqukethwe, umlilo yokuncwaninga izinsimbi kanye namakhemikhali ukuhlaziywa anganika obukholisayo imiphumela yawo wonke amaqembu e ingxabano. Lokhu kungenxa yokuthi i-Assay umlilo kunezinzuzo eziningi eziyingqayizivele ukuthi ezinye izindlela kohlaziyo akudingeki:

 

(1) Okuhle amasampuli representativeness. Igolide nesiliva kukhona Ukuboshelwa ngokuvamile ekhona isampula ngomyalo<g / t. I Assay umlilo has a usayizi esikhulu isampula, ngokuvamile 20-40g, futhi amasampula kuze 100g noma ngaphezulu zingafundwa. Ngakho-ke, ummeleli isampula muhle. Iphutha izibonelo zalokho kuyehla kube okungenani.

 

(2) nezimo Wide. Kungaba ukuzivumelanisa cishe zonke amasampula, kusukela netshe, igolide CONCENTRATE ukuba ingxubevange igolide, indlela umlilo Assay ungakwazi ukunquma ngokunembile ngegolide nangesiliva, kuhlanganise nalezo antimonites ezingeke ingaxazululwa ngokuthi ukuhlaziywa ezimanzi. Ukuze ukuhlaziywa yezingxenye esemqoka ngegolide elihlanzekile, le Assay umlilo futhi bathole imiphumela eyanelisayo. Ngaphandle amasampula ezimbalwa kakhulu, le ndlela kungenziwa ingashintshwa ukuze cishe yonke namaminerali.

 

(3) Ukusebenza kahle nokunonophala kuphezulu, ukufinyelela izikhathi ezingaphezu kweshumi eziyinkulungwane. Inani elincane zegolide nezesiliva kungenziwa quantitatively ahlanganiswe kusukela amashumi amagremu amasampula oqukethe semali izakhi-matrix ku inkinobho yokuhlola igolide. Ngisho uma micrograms zegolide nezesiliva kuyacetshiswa, ukulahlekelwa amancane kakhulu, -generally kuphela amaphesenti ambalwa. Ngenxa ukwakheka okulula granule kwakwakhe (noma nokunonophala slag), kuyazuzisa ukusebenzisa izindlela test obehlukene ukuhlonza esikhathini esizayo.

 

(4) Imiphumela ukuhlaziywa zinokwethenjelwa futhi kunembile. ukuhlaziywa South African Rand yeNkampani isimiso segolide elihlanzekile (>99,9%), 74 ukuhlaziywa imiphumela isampula esifanayo, ukuphambuka okujwayelekile (S) 0.0058%. I S-10 ukuhlaziywa Imiphumela imikhiqizo efanayo yasekhaya futhi mayelana 0,005%. Kule minyaka edlule, ezinye izazi ekhaya aphesheya baye bazama esikhundleni ngokuphelele Assay umlilo nge ezimanzi ahlukahlukene okuhlaziya amakhemikhali amasha noma ukuhlaziywa wezinsimbi, kodwa bona baye akukaphumeleli. Werbicki et al. kuqhathaniswa izindlela ezintathu kohlaziyo lase-Au e isixazululo-Aas, ICP-AES, futhi indlela Assay, wabanika abafundi ejwayelekile ukuphambuka S kwendlela ngayinye ngokuzuzisayo laboratories 18. Umphumela ukuthi ICP-AES futhi Aas izindlela eziyisisekelo Ngokuvumelana, kodwa zonke kancane okubi kakhulu ukwedlula indlela Isivivinyo igolide Wall waveza ukuthi indlela umlilo Assay kufanelekile amasampula ne wokuqukethwe igolide<1μg ~ 1g, futhi ukunemba kwayo nokunemba zingcono kunezinye ukuhlaziywa wezinsimbi.
