Enwere ọtụtụ ụdị dị iche iche teknụzụ uru igwe dị. Onye ọ bụla nwere uru na ọghọm ya na nke ọ bụla na-eji usoro dị iche iche nweta otu ihe ahụ. Akụkọ a, ST Equipment & Technology (STET), will walk you through the characteristics of different iron ore beneficiation technology.
E nwere nzọụkwụ atọ bụ́ isi maka mmepụta ígwè—egwupụta ihe, nhazi, na pelletizing. Mining is the process of taking ígwè ore site n'ala; nhazi ahụ na-ewepụ ihe niile na-abaghị uru (gangu). Inweta ọkwa dị iche iche nke ihe mejupụtara kemịkalụ na pelletizing na-atụgharị ihe ndị emechara ka ọ bụrụ obere, eji arụ ọrụ unit. Processing iron ore is the most important step in the production of pellets and many different techniques have been used and developed.
Ozugbo a na-ewepụta ihe ndị dị na ígwè ígwè n'ala, A ghaghị ịhazi ha ka ha wee mee ka ọdịnaya nke ígwè dịkwuo elu ma belata ntinye nke mineral gangue. Nkwụnye ego ọ bụla nwere akụrụngwa kemịkalụ pụrụ iche. Iji mepụta igwe eji eme ihe (Fe), A ga-ewepụrịrị mineral ndị ọzọ na ọla. Ihe mineral ndị ọzọ nwere ike imerụ ígwè ígwè bụ silica- na mineral ndị na-ebu alumina dị ka quartz, kaolinite, gibbsite, diaspore, and corundum.
Akụrụngwa teknụzụ nkewa na-enye ohere ka ahazi ezigbo ígwè dị obere ka ọ bụrụ ọla igwe dị elu nke ukwuu. The different types of separation technology equipment fall into two main categories—wet and dry iron ore separation.
N'ime mmiri mmiri iron ore uru teknụzụ, enwere usoro ole na ole dị iche iche. This includes flotation and different intensities of wet magnetic separation.
Flotation a na-ejikarị ya na nkewa magnetik eme ihe. Usoro a na-eji reagent kemịkalụ nke na-eme ka ígwè ahụ jidesie mmeghachi omume ahụ ike ma kewapụ ya na ihe ndị ọzọ. Na mgbakwunye na iji kemịkalụ, mmiri dị mkpa iji hụ na mmeghachi omume na-arụ ọrụ nke ọma. N'ihi ya, A na-emepụta ọtụtụ mmiri mkpofu na a na-achọkwa ọgwụgwọ mmiri. N'otu aka ahụ, iji hụ na ụfọdụ n'ime ihe ndị dị mma dị iche na ígwè, desliming dị mkpa. Otú ọ dị, desliming can result in the loss of the iron particles as well.
Nkewa Igwe Ọdụdọ Wet (Ike dị ala na ike dị elu) Site na usoro nkewa magnetik mmiri mmiri, a na-edobe ihe ndị a na-etinye n'ígwè n'ime drum magnetik na-agbanye mmiri n'ime ya iji nyere aka kewaa ihe ndị ahụ.. Dabere na ihe mejupụtara ihe dị na drum, enwere ike iji ike ndọta dị ala ma ọ bụ nke dị elu iji kewaa ahụ.. ọzọ, A na-emepụta mmiri na-ekpofu mmiri na ọgwụgwọ mmiri ga-adị mkpa.
N'ime akọrọ ígwè nkewa, enwere a ole na ole usoro nke enwere ike iji. Ha gụnyere ikewapụta ike ndọda, akọrọ magnetik nkewa, akọrọ magnetik nkewa.
akọrọ magnetik nkewa akọrọ magnetik nkewa. akọrọ magnetik nkewa, akọrọ magnetik nkewa. akọrọ magnetik nkewa, akọrọ magnetik nkewa, akọrọ magnetik nkewa. There are many different machines that use gravity as the main separation method.
akọrọ magnetik nkewa bụ otu ihe ahụ dị ka nkewa magnetik mmiri ma ọ bụrụ na ọ naghị eji mmiri nyere aka mee ka usoro nkewa dị mfe. Kama, ọ na-adabere naanị na magnetik Njirimara nke mineral kewapụ ha na ibe. Dry magnetic separation is not very effective on fine particles.
Nkewa Electrostatic STET kpọrọ nkụ bụ ihe kacha mma akọrọ ígwè ígwè nkewa technology akụrụngwa dị maka ezi, ma ọ bụghị ya, ígwè ígwè a na-apụghị ịgbakete. This process uses the negative and positive charges of iron to separate it from other minerals.
Enwere ọtụtụ uru iji STET akọrọ electrostatic nkewa. N'adịghị ka ndị ọzọ akọrọ ore nkewa ụzọ, nkewa nke electrostatic na-enye ohere maka mgbake nke ọla ígwè nke ga-efunahụ ma ọ bụghị na sekit nhazi nhazi. Na mgbakwunye, ọ na-enye ohere maka obere ego / ụgwọ ọrụ ma na-ebute mmetụta dị nta na gburugburu ebe obibi (na-ekwe ka mfe ikwe). N'otu aka ahụ, nkewa electrostatic na-egbochi mkpa maka oriri mmiri, eji kemịkalụ, and eliminates the storage/disposal of wet tailings.
Ị na-achọ ihe ọzọ na-erite uru iron ore nke na-enweghị mmiri? STET akọrọ electrostatic nkewa bụ gị ngwọta. ST Equipment & Technology (STET) na-enye ezigbo ígwè ígwè nkewa maka ndị ahịa n'ụwa nile.
