Mmekọrịta nke sodium sulfide na ndị ọzọ reagents na usoro flotation

Na ubi nke Nhazi mineral, flotation bụ usoro a na-ejikarị eme ihe maka ikewapụta mineral bara uru na gangue. Sodium sulfide na-arụ ọrụ dị oke mkpa na usoro a, a na-ejikarị emezi uru pH nke pulp, sulfidize, ịda mbà n'obi, na iyipụ elu nke mineral. Mmekọrịta ya na Ndị na-anakọta, Ụmụnna, na Ndị na-achịkwa dị mgbagwoju anya na mmetụta dị ukwuu na arụmọrụ na selectivity nke flotation.

Mmekọrịta na ndị nchịkọta

Mmetụta na Sulfide Mineral Collectors

Maka ndị nchịkọta a na-ejikarị eme ihe maka mineral sulfide dị ka xanthates na dithiophosphates, mgbe usoro onunu ogwu. Sodium sulfide kwesịrị ekwesị, ọ nwere ike welie hydrophobicity nke sulfide ịnweta n'elu, na-enyere ndị na-anakọta aka adsorb mma na ịnweta elu ma na-eme ka floatability nke mineral. Agbanyeghị, mgbe sodium sulfide karịrị akarị, ọ ga-etolite ihe nkiri hydrophilic n'elu mineral sulfide, na-egbochi nnabata nke ndị na-anakọta ma si otú a na-arụ ọrụ mgbochi. Dịka ọmụmaatụ, na flotation nke ọla kọpa-sulfur ore, ego kwesịrị ekwesị nke sodium sulfide nwere ike ịkwalite mkpokọta chalcopyrite site na xanthate, ebe oke oke ga-egbochi flotation nke chalcopyrite.

Mmetụta na Oxide Mineral Collectors

Na flotation nke oxide mineral, sodium sulfide nwere ike sulfidize elu nke oxide mineral, na-ekwe ka ha na-anakọta site sulfide ịnweta mkpokọta. Dịka ọmụmaatụ, mgbe ị na-eji ndị na-anakọta fatty acid na-ese n'elu cerussite, sodium sulfide na-ebu ụzọ mee ka elu nke cerussite na-emekọ ihe, wee soro onye nchịkọta acid fatty na-emekọrịta ihe, na-eme ka mmetụta flotation nke cerussite dịkwuo mma.

Mmekọrịta na Frothers

Sodium sulfide n'onwe ya enweghị ihe na-agbapụta ụfụfụ, ma ọ nwere ike imetụta njirimara nke pulp na ala ala nke mineral, si otú ahụ na-emetụta mmetụta ụfụfụ nke frothers. Ọnụ ego sodium sulfide kwesịrị ekwesị na-eme ka elu hydrophobicity nke mineral dị mma, nke na-eme ka ntinye nke egosipụta na mineral, na-eme ka mmetụta aeration dịkwuo elu na nkwụsi ike nke ụfụfụ nke frothers. Otú ọ dị, oke sodium sulfide ga-agbasasị slime dị mma na pulp, mee ka viscosity pulp dịkwuo elu, mee ka ụfụfụ ahụ dị nro, ma na-emetụta nkwụsi ike na mmiri mmiri nke ụfụfụ ahụ, nke na-adịghị mma maka ikpochapụ ụfụfụ nke flotation na nkewa nke itinye uche.

Mmekọrịta ya na ndị nchịkwa ndị ọzọ

Mmetụta mmekọrịta na pH Regulators

Sodium sulfide na-aghọ alkaline ma nwee ike ịrụ ọrụ na ndị na-achịkwa pH ndị ọzọ dịka lime na sodium. carbonA na-eme ka ọ dị mfe ịhazi pH nke pulp ahụ. Dịka ọmụmaatụ, n'ime mmiri mmiri nke lead-zinc ore, a na-ejikarị sodium sulfide na lime eme ihe iji mee ka pulp ahụ nwee alkaline, gbochie ihe ndị na-adịghị ọcha dị ka pyrite, ma melite nhọrọ flotation nke lead-zinc ore.

Mmekọrịta na ndị na-akụda mmụọ

Sodium sulfide nwere mmetụta mgbochi yiri nke ahụ na ụfọdụ ndị nkụda mmụọ dịka cyanide na iko mmiri. N'ọnọdụ ụfọdụ, enwere ike iji ha jikọtara ọnụ iji kwalite mmetụta mgbochi. Dịka ọmụmaatụ, na flotation nke ọla kọpa-lead-zinc polymetallic ore, ijikọta ojiji nke sodium sulfide na cyanide nwere ike iwusi mgbochi nke sphalerite na pyrite ike, na-enweta nkewa dị irè nke ọla kọpa-isi na zinc-sulfur. Otú ọ dị, ekwesịrị ịṅa ntị na ịchịkwa usoro onunu ogwu na mgbakwunye; ma ọ bụghị ya, oke mgbochi nwere ike ime, na-emetụta ọnụego mgbake.

Mmekọrịta na Activators

Sodium sulfide nwere mmetụta ịgbalite na ụfọdụ mineral egbochiri ma enwere ike iji ya na ndị na-eme ihe. Dịka ọmụmaatụ, na flotation nkewa nke sulfide ọla kọpa-lead ore, galena nke cyanide na-egbochi nwere ike rụọ ọrụ site na sodium sulfide wee kpokọta ya site na ethyl thionocarbamate iji nweta nkewa nke ọla kọpa na ụzọ. N'otu oge ahụ, sodium sulfide nwekwara ike imetụta mmetụta nke ndị ọzọ activators. Dịka ọmụmaatụ, oke sodium sulfide nwere ike iri ion na-arụ ọrụ na pulp, na-ebelata mmetụta ịgbalite nke ndị na-eme ihe.

N'ikpeazụ, ịghọta mmekọrịta nke sodium sulfide na ndị ọzọ reagents na usoro flotation bụ ihe dị oké mkpa maka ịkwalite usoro flotation, melite ọnụego mgbake na ọkwa nke mineral bara uru, na ibelata ọnụ ahịa nhazi ịnweta. Ndị injinia na-edozi mineral kwesịrị iji nlezianya dozie usoro onunu na mgbakwunye nke reagents dị iche iche dabere na njirimara nke ore iji nweta nsonaazụ kacha mma.
