Ọrụ nke ọla kọpa sulfate na ụlọ ọrụ nhazi nke ịnweta

Na mgbagwoju na dị oké mkpa ubi nke Nhazi mineral, dị iche iche kemịkalụ reagents na-arụ dị oké mkpa ọrụ na optimizing nkewa na mmịpụta nke bara uru minerals. Ọla kọpa sulfate, ya na kemịkalụ ya dị iche, apụtala dị ka ihe reagent nke ukwuu na ụlọ ọrụ a. Isiokwu a na-abanye n'ime ọrụ dị iche iche nke Ọla kọpa sulfate na nhazi nke ịnweta, na-enyocha usoro ya na ngwa ya.

Ntinye nke mineral

Otu n'ime ọrụ bụ isi na nke a ma ama nke ọla kọpa sulfate na nhazi ịnweta bụ ọrụ ya dị ka onye na-eme ihe. Na sulfide ore Flotị, dịka ọmụmaatụ, ọ nwere ihe dị ịrịba ama Tinye n'ọrụ mmetụta na ọtụtụ mineral dị ka sphalerite, stibnite, pyrite, na pyrrhotite, na-enwe mmetụta siri ike na sphalerite.

Usoro ịgbalite

1. Metathesis Reaction iji mepụta ihe nkiri ịgbalite

Mgbe a na-eji sulfate ọla kọpa rụọ ọrụ sphalerite, mmeghachi omume metathesis na-eme. Radius nke ion ọla kọpa divalent yiri nke ion zinc, na solubility nke ọla kọpa sulfide dị obere karịa nke zinc sulfide. N'ihi ya, enwere ike ịmepụta ihe nkiri ọla kọpa sulfide n'elu sphalerite. Mgbe emechara ihe nkiri sulfide ọla kọpa, ọ nwere ike ịmekọrịta ngwa ngwa Ndị na-anakọta dị ka xanthates. Xanthates nwere njikọ siri ike maka ọla kọpa sulfide, nke na-eme ka hydrophobicity nke sphalerite dị elu, na-eme ka ọ dịkwuo mfe ịnweta ịnweta ikuku na ikuku na-ese n'elu, si otú a na-eme ka sphalerite rụọ ọrụ.

2.Wepụ ihe mgbochi na imepụta ihe nkiri ịgbalite

N'ọnọdụ ụfọdụ, ihe ndị ọzọ nwere ike igbochi mineral. Dịka ọmụmaatụ, mgbe sodium cyanide A na-eji ya dị ka onye na-egbochi flotation, ọ nwere ike ịmepụta zinc kwụsiri ike. cyanide ion mgbagwoju anya n'elu sphalerite, nke na-egbochi flotation nke sphalerite. Otú ọ dị, ọla kọpa - cyanide complexion ion kwụsiri ike karịa zinc - cyanide complex ion. Mgbe a na-agbakwunye ọla kọpa sulfate na sphalerite slurry nke cyanide na-egbochi, cyanide radicals n'elu sphalerite na-adapụ, na ions ọla kọpa na-akwụghị ụgwọ wee meghachi omume na sphalerite iji mepụta ihe nkiri na-arụ ọrụ nke ọla kọpa sulfide, si otú ahụ na-emegharị sphalerite maka flotation.

Iwu nke Slurry pH

Ọla kọpa sulfate na-ejekwa ozi dị ka onye na-achịkwa ihe na-edozi slurry nke ịnweta, karịsịa n'usoro nhazi pH. Uru pH nke slurry bụ ihe dị oke egwu nke na-emetụta ọdịdị elu nke mineral na arụmọrụ nke reagents flotation.

Mgbe a na-agbakwunye sulfate ọla kọpa na slurry, ọ nwere ike ịnweta hydrolysis na mmiri. Sulfuric acid nke na-esi na ya pụta nwere ike ime ka ntinye hydrogen ion dị na slurry, si otú a na-ebelata uru pH. Na uru pH kwesịrị ekwesị, sulfate ọla kọpa nwere ike imeghachi omume na ion hydrogen n'elu ala ịnweta iji mepụta ihe kemịkal na-ejikọta na elu ịnweta. Mmeghachi omume a nwere ike ịbawanye hydrophilicity na buoyancy nke ịnweta, na-akwalite mmetụta flotation. Dịka ọmụmaatụ, na ụfọdụ ọla edo - na-ebu ores, imezi pH nke slurry na ọla kọpa sulfate nwere ike ime ka mmekọrịta dị n'etiti ọla edo - na-ebu mineral na ndị na-anakọta, na-eme ka mgbake nke flotation nke ọla edo.

Mgbochi nke mineral na-achọghị

Na mgbakwunye na ịgbalite, sulfate ọla kọpa nwekwara ike ịrụ ọrụ dị ka ihe mgbochi n'ọnọdụ ụfọdụ. Na usoro flotation, ọ na-adịkarị mkpa ikewapụ mineral ndị a na-achọsi ike na mineral ndị ọzọ na-achọghị. Enwere ike iji sulfate ọla kọpa gbochie mmiri nke mineral ndị na-abụghị ebumnuche.

Mgbe agbakwunyere na slurry, ọla kọpa sulfate nwere ike ịmepụta anions nke a na-etinye n'elu mineral ndị ọzọ na-adịghị achọ ka mmiri na-ese n'elu mmiri. Mgbasa ozi a na-ebelata hydrophilicity na ihe na-akpali akpali nke mineral ndị a na-abụghị nke ezubere iche, na-egbochi ka a na-ese n'elu ya na mineral ebumnuche. Dịka ọmụmaatụ, na usoro flotation ebe ihe mgbaru ọsọ bụ ikewapụ ọla edo ọla na ụfọdụ mineral gangue, na-agbakwunye ọla kọpa sulfate inhibitors na slurry nwere ike idobe mineral gangue na ala nke flotation cell ka na-ekwe ka ọla edo mineral na-ese n'elu n'elu site n'enyemaka nke ndị na-anakọta na afụ.

Mgbanwe nke elu igwe

Ọla kọpa sulfate nwere ike rụọ ọrụ dị ka ihe ngbanwe nke ịnweta, na-agbanwe kemịkalụ na ihe anụ ahụ nke elu ịnweta. Na ọla edo flotation, ihe ọkụ eletrik na hydrophilicity nke elu ịnweta bụ isi ihe na-emetụta arụmọrụ flotation.

Na ịnweta slurry, ọla kọpa sulfate nwere ike ịmepụta ọla kọpa - nwere ion. Ion ndị a nwere ike imeghachi omume na ion metal n'elu ịnweta, na-agbanwe ọdịdị kemịkalụ elu ya. Dịka ọmụmaatụ, n'elu ụfọdụ ọla edo - na-ebu mineral na ụfọdụ oxide oyi akwa, ọla kọpa - nwere ion nwere ike imeghachi omume na ion ígwè dị na oyi akwa oxide, na-emepụta ogige kemịkal ọhụrụ n'elu. Nke a nwere ike ịgbanwe n'elu ụgwọ na chemical reactivity nke ịnweta.

Ọzọkwa, ọla kọpa sulfate nwekwara ike imetụta hydrophilicity nke ịnweta elu. Site n'ịbawanye mpaghara kọntaktị n'etiti mineral na mmiri, ọ nwere ike melite mgbasa nke mineral na slurry. Mgbasasa a kwalitere nwere ike ịba uru maka ihe ndị nchịkọta na-esote. Mgbe agbakwunyere ndị na-anakọta, ha nwere ike ịmekọrịta nke ọma na ebe ịnweta ihe ndị a gbanwere, na-akwalite ntinye nke mineral na afụ ikuku na n'ikpeazụ kwalite mmetụta flotation nke ogbunigwe ọla edo.

mmechi

Na nchịkọta, ọla kọpa sulfate na-arụ ọrụ dị iche iche na nke dị mkpa na ụlọ ọrụ nhazi ịnweta. Dị ka onye na-eme ihe, ọ nwere ike ịkwalite arụmọrụ flotation nke mineral dị ka sphalerite site n'ịmepụta ihe nkiri ma ọ bụ wepụ ihe mgbochi. Dị ka onye na-achịkwa, ọ na-enyere aka ịkwalite pH slurry, nke dị oké mkpa maka ịrụ ọrụ nke ọma nke usoro flotation. Dị ka onye na-egbochi ya, ọ nwere ike ịhọrọ igbochi flotation nke mineral na-achọghị, na-eme ka ịdị ọcha nke njedebe ikpeazụ. Na dị ka a ịnweta elu modifier, ọ nwere ike ịgbanwe kemịkalụ na anụ ahụ Njirimara nke ịnweta na-ebupụta, na-eme ka mmekọrịta dị n'etiti mineral na flotation reagents. Iji ọla kọpa sulfate mee ihe n'ụzọ kwesịrị ekwesị na nhazi ịnweta ọ bụghị nanị na-eme ka nrụpụta nke ikewapụta mineral dịkwuo mma kamakwa ọ na-enye aka na iji akụ ịnweta akụ na-adịgide adịgide na akụ na ụba.
