Theory Flotation nke ọla edo

A na-emepụta ọla edo na steeti efu na ore.Ihe mineral ndị a na-ahụkarị bụ ọla edo eke na ọla ọla edo.Ha niile nwere ezigbo floatability, ya mere flotation bụ otu n'ime ụzọ dị mkpa maka nhazi ọla edo.A na-ejikọta ọla edo na ọtụtụ mineral sulfide.Symbiotic, karịsịa symbiotic na pyrite, ya mere flotation nke ọla edo na flotation nke metal sulfide ore dị ka pyrite na-ebu ọla edo nwere njikọ chiri anya na omume.Omume flotation nke ọtụtụ concentrators anyị ga-ewebata n'okpuru bụ ọtụtụ ọla edo nke ọla edo na mineral sulfide na-ebikọ ọnụ.

Dabere n'ụdị na ọnụọgụ nke sulfides, enwere ike ịhọrọ nhọrọ ọgwụgwọ ndị a.
① Mgbe sulfide na ore bụ tumadi pyrite, na e nweghị ndị ọzọ arọ metal sulfide, na gold bụ tumadi na ọkara na ezi ahụ na symbiotic na ígwè sulfide.A na-efegharị ụdị ọla ndị dị otú ahụ iji mepụta ọla edo sulfide, ebe ikuku na-ekupụta mmiri na-agbapụtakwa ebe mmiri na-ekpu mmiri, si otú ahụ na-ezere ọgwụgwọ cyanidation nke ọla dum.Enwere ike izipu ihe nleba anya nke flotation na osisi pyrometallurgy maka nhazi.Mgbe ọla edo na-abụkarị n'ụdị nke submicroscopic particles na pyrite, mmetụta cyanide leaching kpọmkwem nke itinye uche adịghị mma, a ga-eghekwa ya ọkụ iji kesaa ihe ndị ahụ ọla edo wee hapụ ikuku.

② Mgbe sulfide dị na ore nwere obere chalcopyrite, sphalerite, na galena na mgbakwunye na iron sulfide, ọla edo bụ symbiotic na pyrite na sulfides metal ndị a dị arọ.Atụmatụ ọgwụgwọ izugbe: Dị ka usoro ọdịnala na usoro kemịkalụ nke metal sulfide ore na-abụghị nke ferrous, weghara ma họrọ itinye uche kwekọrọ.A na-ezigara uche na smelter maka nhazi.Ọlaedo na-abanye ọla kọpa ma ọ bụ ndu (na-abụkarị ihe na-etinye ọla kọpa) na-etinye uche wee nwetaghachi ya n'oge usoro mgbaze.Enwere ike ịfegharị akụkụ ebe ọla edo na sulfide iron bụ symbiotic iji nweta iron sulfide concentrate, nke enwere ike nwetaghachi ya site na ịsa nri na nku ikuku.

③ Mgbe enwere sulfides na-emerụ ikuku na ore, dị ka arsenic, antimony, na sulfide nke sulfide, a ga-asachapụta sulfide nke enwetara site na flotation iji gbaa arsenic, sulfide na ọla ndị ọzọ dị na itinye uche n'ime ngwa ngwa Maka metal oxides na-agbanwe agbanwe. , gwerie slag ọzọ wee jiri mkpịsị akwụkwọ wepụ ọla oxides na-agbanwe agbanwe.

④ Mgbe akụkụ nke ọla edo dị na ọla dị na steeti efu, akụkụ ọla edo bụ symbiotic na sulfide, na akụkụ nke ọla edo na-etinye n'ime mineral gangue.A ghaghị ị nwetaghachi ọla ndị dị otú ahụ na nkewa ike ndọda iji nwetaghachi ọla edo n'efu, na iji nwetaghachi symbiosis na sulfide site na flotation Maka ọla edo, dabere na ọdịnaya ọla edo nke ọdụ ụgbọ mmiri, ọ dị mkpa ịtụle ma ị ga-eji leaching kemịkal.Enwere ike ịkụda ihe nlegharị anya nke flotation nke ọma wee wụsa ya ozugbo, ma ọ bụ ihe fọdụrụ n'ọkụ nwere ike ịkụcha nke ọma mgbe akpọchara ya wee kpoo ya.
