Tsvina simbi Kugadzirwa

Chimwe chikuru sectors hwenyika ndiyo simbi. Rinotibatsira yakatsvuka zvinhu, nezvimwe maindasitiri. Ferrous uye non-ferrous nesimbi inodiwa zvinenge kwose kwose. Uye mutengo izvi mbishi zvinhu zviri kuwedzera zuva nezuva. Energy mitengo, Chokwadi, kuchikosha chaizvo mutengo simbi zvigadzirwa. Asi basa rinokosha nokuumbwa uye kugadzirwa tsvina kunoita mitengo.

Zvino simbi dzavo kunyanya guru. Anogara munzvimbo huru uye nokudaro isva mhepo chepfu yeimwe, mvura uye ivhu. Uye panguva imwe chete riri pekugara mari dzavo, kuchengetwa uye kutakurwa chinokosha simba pamusoro mari inoshandiswa pane metallurgia mabhizimisi. Asi zvokudya izvi zvine zvakawanda zvinhu zvinogona kushandiswa yechipiri mbishi zvinhu. Zvino nzira yatenzi, metallurgia namatongo yakadaro inogona ikava kunobva mari.

matongo izvi zvinobva kuna simbi kwakaita sesimbi, vakakanda simbi kana ferroalloys. Uye zviri siyana chicherwa zvinoriumba, izvo zvingasanganisira simbi, anogona kunge yakatokura mavari kupfuura mune imwe dzinongoitika ores. Uye nokuda kukwana kudzidza marongerwo uye zvivako zviri sludges pane dambudziko shandisazve yavo.

Get zvichida steelmaking gang. Izvi recyclable tsvina kurimwa munzvimbo zhinji simbi zvigayo uye mafekitari dzikwanise zvakapfumisa gang. Nokuda kwaizvozvi "pakaoma" rinobva kuparadzana zvigadzirwa vakawana pashure kupwanya pamusoro gang. A unobatsira chigadzirwa akawana pashure kurapwa ichi, maranjisi ropa vaiona simbi hombe uye aggregates nesimbi uye silica girazi. Iron-zvakapfumisa gang sezvamunoita achiri muduku. Uye somugumisiro vapfume panguva sinter miti ematani gang anogadzirwa vanenge 40 makirogiramu nesimbi. The yasara tsvina, ane blotches diki chete kana simbi oxide uchaguta munzvimbo chipande.

Asi pane zvimwe zvokufambisa michina kuti vapfume yacho simbi gang. Achibatsirwa matongo izvi zvinogona kuwana zvigadzirwa matatu. Chokutanga chakaumbwa chigadzirwa. Zvaiva vanenge 10% of gang vakawanda. Zviri kunze esimbi simbi, rine kuduku tsvina regirazi, silicates uye carbonates. Ake briquetted akatuma kuti smelter yechipiri. Wechipiri madota-yesimbi oxide chigadzirwa. Zviri about 22% yose inowanwa. Iron mune chigadzirwa ichi zvishoma. Kazhinji kacho, inoitwa zvicherwa siyana. Izvi wustite, magnetite, maghemit, goethite, hematite, hydrated madota, simbi uye calcium yakawanda carbonates, uyewo magnesium uye calcium yakawanda ferrites. chigadzirwa ichi chinogona kushandiswa senzira yepamusoro zvokudya zvokunyama zviri kugadzirwa nesimbi sinter fluxed. Zvino vakasara, riri pamusoro 68% inowira silica chigadzirwa. Its chikuru chikamu ine zvicherwa: silicates, spinels, tridymite, silicate girazi uye madota hydration zvigadzirwa. Izvi tsvina hausi maturo. Silicate chigadzirwa inoshandiswa kunyanya kuvaka, simende kana zvimwe cementitious zvinhu.

Munogonawo kutora gang ferromanganese kugadzirwa, ane zvakawanda zvinokosha zvinoriumba. Iri maranjisi ropa ferromanganese uye esimbi simbi, silicates, hydroxides, oxides aggregates, manganese uye carbonates simbi, silicate magirazi, uye zvibereko zvayo crystallization. Masayendisiti muitiro naro nomufambiro yakaoma regiravhiti wevasungwa pamusoro zvinokachidza izvi. Somugumisiro izvi tsvina dzinoita kugadzirwa zvinhu zvitatu.

Chokutanga izvi ndiyo simbi manganese Kuisa pfungwa pachinhu chimwe. Of zvachose guru gang unogona kusimuka kusvika 17%. chigadzirwa ichi rine simba rinonzi magnetic uye non-rinobva zvikamu simbi, manganese, Cohen simbi uye alloys siyana pamwe kunosiyana zviri manganese nedare, uye avo oxides uye hydroxides. Shandisa chigadzirwa Izvi zvinogona kuva kugadzirwa ferromanganese.

The chigadzirwa wechipiri ane jecha silicate. Hafu zvachose gang uremu inowira pamusoro pake. jecha Silicate rinoumbwa zvikurukuru pamusoro Goldstone, cristobalite, tridymite, girazi uye silicates. Pairi unogona kubereka silicomanganese kana kurishandisa somunhu chivakwa zvinhu.

The yasara 33% kunobva ivhu-carbonate guruva. It rinoumbwa dzakarukwa zvakanaka yakakamurwa silicates, carbonates, girazi nezvimwe zvicherwa. guruva iyi inoshandiswa simende kugadzirwa. Kune zvakawanda kwaiita dongo, iro rinogona kubatsirwa vanhu.
