Zabi Harshe:
Yayin da damuwar dindindin da ke shafar canjin yanayi ke ƙaruwa, environmentally friendly methods in the mining and mineral processing industries have become a major source of interest.
Sabbin abubuwan ci gaba a cikin sarrafa ma'adinai na bushewa suna saurin sauya hanyoyin rigar, da ST Kayan aiki & Technology, a leader in electrostatic rabuwa yana a saman fakitin tare da sabbin abubuwan sa.
Ore wani lokaci ne na ko dai ƙarfe na asali ko ma'adinai mai ɗauke da ƙarfe ko dutse wanda aka haƙa don riba. Yin aikin ma'adinai shine matakin farko na tama da zarar ta bar mahakar. Tsarin ya kunshi shirye -shiryen tama, milling, da suturar tama, wanda aka fi sani da amfana.
Amfanuwa ta hanyar injiniya yana raba hatsin ma'adanai daga gangue (low-darajar) ma'adanai da ke kewaye da su domin samar da wani taro wanda ya ƙunshi ma'adanai masu amfani.
Ana iya yin wannan rabuwa ko ta jiki, ta hanyar rabuwa mai nauyi, electrostatic rabuwa, and magnetic separation, ko ta hanyar kimiyya, ta amfani da ruwan sanyi, leaching, da electrowinning. Ma'adanai marasa amfani, wadanda galibi ana jefar dasu cikin madatsun ruwa, ana kiran su tailing.
Domin fahimtar fa'idar sarrafa ma'adinai busasshe, dole ne ku fara fahimtar yadda ta bambanta da sauran hanyoyin.
Froth flotation ya samo asali ne daga ƙarshen karni na 19 kuma shine hanyar farko da masana'antun hakar ma'adinai suka haɓaka don ware ma'adanai da ma'adinan.
Froth Flotation, wanda kuma ake amfani da shi a masana'antar sarrafa takarda da masana'antar sarrafa ruwa, yana aiki akan ƙa'idojin yawa da kaddarorin ruwa na barbashi na ma'adinai. Rabuwa na faruwa ne lokacin da aka jiƙa ma'adanai a cikin wani sinadari, haddasa kayan da aka tara bisa la’akari da ko su na ruwa ne (mai hana ruwa) ko hydrophilic (mai jan ruwa).
Froth flotation yana amfani da ruwa mai yawa da aka haɗe da wakilan sinadarai, yawancin abin da ba a iya bayyanawa. Da zarar an sarrafa shi dole ne ya bushe kafin haihuwa. Wannan yana nufin ba hanya ce mai mahalli sosai ba.
Dry beneficiation yana raba kwayoyin ma'adinai bisa bambance -bambancen da ke tsakaninsa, siffar, girma, haske, siffar, wutar lantarki da/ko mai saukin kamuwa da maganadisu. Magnetic da electrostatic/tribo-electrostatic rabuwa sun fada cikin wannan rukunin. Kamar yadda sunan ya nuna, yana amfani da ƙasa, idan wani ruwa fiye da ƙanƙantar da ruwa, rage yawancin rashin amfanin rigar niƙa.
Electrodynamic da Electrostatic – are the main types of electrostatic separators. These work in a similar manner, but differ in which forces are applied to particles, Ina nufin, janyewar electrostatic ko girma. Rarraba nauyi yana amfani da sojojin centrifugal da suka dace da takamaiman ƙarfin ma'adinai da gangue don raba su.
Rabuwa na Magnetic yana aiki ta hanyar motsi barbashi a cikin filin magnetic don rarrabe gangue da tama mai amfani.
Fa'idodin busasshen amfanin sun haɗa da haɓaka yawan aiki da aminci, dorewa, kuma babu shara. Baya ga rage yawan amfani da ruwa, this method has fewer production phases and uses less power and equipment.
Kawar da ruwa kuma yana cire buƙatar hanyoyin tsabtace ruwa masu tsada, gami da yin famfo, nunawa, tace, da centrifuging.
Kasancewa a cikin Needham, Massachusetts, mun ƙirƙiri mai rarrafewar wutar lantarki mai rarrafe wanda ke rarrabe ma'adanai gwargwadon sauƙin su, Ina nufin, yadda barbashi ke amsawa lokacin cajin wutar lantarki ta hanyar tuntuɓe a filin lantarki. Not only is it revolutionizing minerals processing, it’s also proven to be highly effective for abinci & feed separation. When used to beneficiate flours, abinci, gina jiki tattara, da fiber.
Domin mafi kyawun bushewar kayan aiki a cikin masana'antar, duba komai fiye da Kayan aikin ST & Technology LLC (STET). It is leading the way in the minerals separation industry. Our triboelectric separation beneficiates micron-size particles through a totally dry process. It requires no additional materials or drying time and reduces the carbon footprint.
