Red apịtị bụ n'efu ngwaahịa N'ịbụ ihe a maara dị ka Flo Rida feat Usoro anụcha bauxite na-emepụta alumina (aluminum oxide). Via a ọcha usoro, alumina nwere ike nụchara anụcha na-emepụta aluminum. Otú ọ dị, bauxite-nke bụ ihe kasị mkpa ore maka amị aluminum-ike ịnwe naanị 30-60% aluminum oxide. Ndị fọdụrụ mejupụtara mejupụtara silica, ígwè na ndị ọzọ dị iche iche ọla na oxides.
Ịtụle n'ụwa nile ina aluminum na ego nke bauxite ka e wepụ alumina, enwere nnukwu ọdọ mmiri nke red apịtị a na -ejide ya na mpaghara mkpochi gburugburu ụwa. O doro anya na, nke a bụ isi na gburugburu ebe obibi nsogbu-n'ihi na elu alkalinity nke sludge-na-achọ echiche ọhụrụ na ike ga-eji hazie ndị n'efu stream.
Otu echiche bụ-eji usoro ndị bauxite site a akọrọ nkewa usoro nke nwere ike itinye uche na alumina ma belata ígwè, clays (kaolinite) na ndị ọzọ na inerts tupu ọ na-aga site na Flo Rida feat Usoro. Usoro a na-ebelata ego nke reactive silica na bauxite nri na Flo Rida feat usoro, nakwa dị ka wepụ a pasent nke inerts (dị ka ígwè) na-eme ka red apịtị ọgbọ. N'ihi bụ a elu mkpụrụ nke alumina si bauxite, ala oriri nke caustic soda, ma na ala mpịakọta nke red apịtị eme. Ndị fọdụrụ ala alumina bauxite ihe nwere ike mgbe ahụ ga-eji na mmepụta nke ciment na maka okporo ụzọ wuo ụlọ.
ST Equipment & Technology si proprietary triboelectrostatic belt separator enye a ala ike, ala na-eri ihe ngwọta iji belata red apịtị ọgbọ. Anyị usoro dị irè na kewara minerals na metal ores na na kemgbe iru na mbụ site flotation (mmiri) usoro. The dị iche iche akara ule nke ihe na-emepụta nwere ike na-isi aku akụ maka Ngwuputa arụmọrụ ugbu a na-amị ma ọ bụ na nhazi bauxite. The STET bụ ala na-arụ ọrụ na-eri, elu na kpamkpam na mmiri na chemical free, na-eme ka ọ dị nnọọ environmentally friendly.
Anyị separators nwekwara ike-eji na-na saịtị na Ngwuputa arụmọrụ, na iwepu mkpa (na-eri) maka njem nke ala ọkwa bauxite. The elu-arụmọrụ, multi-ogbo usoro nwere ike ijikwa a elu olu nke ihe onwunwe na-enweghị iji ọtụtụ ume, enye anyị na ndị ahịa na a gụnyere ya ná nsí na nwere ize ndụ ihe (red apịtị), a ukwuu mmepụta nke bara uru ihe na e mbụ eleghara anya, na ala-arụ ọrụ / efefe akwụ ụgwọ.
STET bụ mpako na-eme ihe ọma, ha na elu-uru azịza ka ụwa mgbe-amụba red apịtị nsogbu mgbe nwekwara enye oké gburugburu ebe obibi ọrụ nlekọta. Ka anyị na-arụ ọrụ ọnụ na-eme ka ụwa na a ka mma ebe maka onye ọ bụla.
