Usoro nke irite uru Ígwè maka nra

Ozugbo a na-ewepụta ihe ndị dị na ígwè ígwè n'ala. A ghaghị ịhazi ha iji mee ka ọdịnaya ígwè dịkwuo elu ma belata ntinye nke mineral gangue. A maara usoro a dị ka uru. Dabere n'ụdị akụrụngwa nhazi, usoro irite uru ígwè nwere ike ime ọtụtụ usoro, ma ọ bụ ọ nwere ike were naanị abụọ. Na akụrụngwa ST & Technology (STET) triboelectric separator, ị nwere ike nweta ngwaahịa dị elu na obere oge, na ọnụ ala dị ala.

Usoro ịba uru Iron ore

Enwere ụdị ngwa teknụzụ nkewa dị iche iche nke enwere ike iji mepụta ọla igwe dị elu. Na ụdị ngwá ọrụ ọ bụla, usoro na-amalite site n'igwepịa na egweri. Mgbe ahụ enwere ike ịgbaso ya na nkewa na n'ikpeazụ na mmiri mmiri. Each of these steps is necessary for these processes and can cause the process to take longer and cost more.

Nzọụkwụ 1: Ịzọpịa na-egweri

Iji kewaa nke ọma ihe dị iche iche a na-achọta na nkwụnye ígwè ígwè, a ga-ebu ụzọ kụnye ya ka ọ bụrụ ntụ ntụ na-adịghị mma ma ọ bụ nke dị mma. Nke a na-eme ka ihe dị iche iche nwee ike ịtọhapụ onwe ha ma si otú ahụ dị mfe ikewa. Usoro nchicha na ichicha nwere ike ime ọtụtụ oge ma mee ya n'ọtụtụ ụzọ. The final objective is to create a fine powder that can be separated in the next steps.

Nzọụkwụ 2: nkewa

Nkewa bụ mgbe a na-ekewapụta ihe ndị dị na ígwè na ihe ndị ọzọ a pụrụ ịhụ na ntụ ntụ. A na-ewepụ ihe ndị ọzọ / mineral ndị a iji hụ na nkwụnye ego nke ígwè ígwè ruru ụfọdụ ọdịnaya ígwè. Enwere ọtụtụ ụdị nkewa dị iche iche - ike ndọda, nkewa magnetik, nkewa flotation, na size separators. Enwere ike iji usoro nkewa ndị a jikọtara ọnụ iji mepụta ngwaahịa dị elu.

• akọrọ magnetik nkewa: Na-eji ihe ndọta dị iche iche dị na igwe na ihe gangue kewapụ ígwè ahụ. A na-eme nke a na cyclone, a jig, okpokoro, gburugburu, na ọtụtụ akụrụngwa teknụzụ nkewa ndị ọzọ. A na-ejikwa nkewa ike ndọda kewapụ ihe ndị na-agba agba na ihe ndị mara mma, ya mere ọ nwere ike okpukpu abụọ dị ka onye nkesa nha. Enwere ike iji ya dị ka ọgwụgwọ mbụ tupu nkewa magnetik ma ọ bụ flotation.
• Nkewa magnetik: Na-eji ihe ndọta dị iche iche nke igwe na ihe gangue kewapụ ígwè ahụ. Nke a nwere ike ịgụnye akụrụngwa teknụzụ nkewa dị ka nkewa magnetik dị ala (LIMS), elu gradient magnetik nkewa (HGMS), mmiri dị elu ike ndọta nkewa (HIMS), ma ọ bụ induction mpịakọta magnetik nkewa (IRMS).
• Nkewa Flotation: Na-eji kemịkalụ kemịkalụ igwe mee ka ọ rapara na afụ ikuku. A na-ahọrọ reagent nke ga-eji ígwè eme ihe. Mgbe a na-ewebata reagent na mmiri, ígwè na-arapara n'ahụ ikuku. Flotation is usually used in conjunction with other separation processes and is the last step before dewatering.

Nzọụkwụ 3: Dewatering

Ọtụtụ usoro nkewa ọkọlọtọ chọrọ ka eji mmiri rụọ ọrụ nke ọma. Ozugbo emechara usoro niile, ihe na-esi na ya pụta bụ slushy, slurry agbanwe agbanwe. Iji mee ka ọ ghọọ pellets, a ga-ewepụ ihe mmepụta ahụ. The dewatering process can be done through vacuum filters or pressure filters.

Usoro nkewa nke Triboelectric nke nra iron ore

N'adịghị ka ọkọlọtọ mma ígwè ore nkewa usoro, na triboelectric nkewa usoro bụ nnọọ ngwa ngwa na mfe. Igwe ígwè ahụ na-agafe nzọụkwụ abụọ, usoro egweri, na usoro nkewa. Because this iron ore beneficiation is water-free there is no dewatering needed.

Nzọụkwụ 1: Na-egweri na ịkụpịa

Nkwụnye ígwè ígwè na-aga site n'otu usoro egweri / ịkụpịa dị ka usoro ọkọlọtọ. The objective is to create a fine output that can be separated in the next stage.

Nzọụkwụ 2: Triboelectric Belt Separator

Na nzọụkwụ a, dapụtara ezi ahụ na-nri n'ime a triboelectric belt separator. Nkwụnye ego ígwè ahụ na-aga n'ihu site na isi atụmatụ nke electrostatic nkewa usoro. Nchaji nke irighiri ihe, nkewa nke ahụ, na ike ndọda nkewa nke ahụ. A na-eji otu igwe eme ihe a niile. Ihe si na ya pụta bụ ngwaahịa akọrọ kpamkpam nke dị njikere maka pelletization.

Ngwa teknụzụ nkewa STET

Ka i si hụ, usoro STET chọrọ ọgwụgwọ tupu ọgwụgwọ, usoro nkewa bụ ikuku, na ọ dịghị mkpa maka dewatering. The STET separator bụ ọhụrụ ọzọ ka ọkọlọtọ nkewa technology akụrụngwa. Ọ bụghị naanị na ọ dị irè, mana ya na-ebelata mmetọ, na-azọpụta ego, and makes it easy to get permits.
