Lead zinc ore incasa

Umgangatho wentsimbi ekrwada efunyenwe kwimigodi yelothe-zinc ngokuqhelekileyo ingaphantsi kwe-3%, kwaye umxholo we-zinc ungaphantsi kwe-10%.Umyinge womgangatho welothe kunye ne-zinc kwintsimbi ekrwada emincinci naphakathi yemigodi yelothe ye-zinc imalunga ne-2.7% kunye ne-6%, ngelixa imigodi emikhulu etyebileyo inokufikelela kwi-3% kunye ne-10%.Ukubunjwa kogxininiso ngokuqhelekileyo kukhokelela kwi-40-75%, i-zinc 1-10%, isulfure 16-20%, kwaye ihlala iqulethe isinyithi esihlala sihleli njengesilivere, ubhedu kunye ne-bismuth;Ukwenziwa kwe-zinc concentrate ngokuqhelekileyo malunga ne-50% ye-zinc, malunga ne-30% yesulfure, i-5-14% yesinyithi, kwaye iqulethe ixabiso elincinci lelothe, i-cadmium, ubhedu, kunye neentsimbi ezixabisekileyo.Phakathi kwamashishini asekhaya ane-lead-zinc nemigodi, i-53% inebakala elibanzi elingaphantsi okanye elilingana ne-5%, i-39% inebakala lesi-5% -10%, kwaye i-8% inebakala elikhulu kune-10%.Ngokuqhelekileyo, ixabiso lokugxila kwimigodi ye-zinc enkulu enebakala elikhulu kune-10% limalunga ne-2000-2500 ye-yuan / toni, kwaye ixabiso lokugxila kwe-zinc nalo liyenyuka njengoko ibakala liyancipha.

Indlela yokuxabisa i-zinc concentrate

Okwangoku akukho ndlela idityanisiweyo yexabiso lezinc egxile eTshayina.Uninzi lwabanyibilikisi kunye nemigodi zisebenzisa iSMM (iShanghai Nonferrous Metals Network) amaxabiso e-zinc thabatha imirhumo yokucubungula ukumisela ixabiso lentengiselwano ye-zinc concentrates;Kungenjalo, ixabiso lentengiselwano ye-zinc concentrate inokumiselwa ngokuphindaphinda ixabiso le-zinc yeSMM ngomlinganiselo omiselweyo (umz. 70%).

I-Zinc concentrate ibalwa ngendlela yeemali zokucubungula (TC / RC), ngoko ke ixabiso le-zinc metal kunye neentlawulo zokucubungula (TC / RC) zizinto eziphambili ezichaphazela ingeniso yemigodi kunye ne-smelters.I-TC/RC (Iintlawulo zonyango kunye nokusulungekiswa kwe-concentrate yokucubungula) ibhekiselele ekuqhubeni nasekuphuculeni iindleko zokuguqula i-zinc concentrate ibe yi-zinc esulungekileyo.I-TC ngumrhumo wokulungisa okanye umrhumo wokucokisa, ngelixa i-RC ingumrhumo wokucokisa.Umrhumo wokucubungula (TC / RC) yindleko ehlawulwe ngabavukuzi kunye nabarhwebi kwi-smelters ukucubungula i-zinc concentrate kwi-zinc ecocekileyo.Umrhumo wokucubungula i-TC / RC igqitywe ngothethwano phakathi kwemigodi kunye ne-smelters ekuqaleni konyaka ngamnye, ngelixa amazwe aseYurophu naseMntla Melika aqokelelana ngokubanzi ngoFebruwari kwintlanganiso yonyaka ye-AZA ye-American Zinc Association ukumisela ixabiso le-TC / RC.Umrhumo wokucutshungulwa ubandakanya ixabiso lesiseko sensimbi ye-zinc esisigxina kunye nexabiso elihla linyuka linyuka ngokunyuka kwexabiso lentsimbi.Ukulungelelaniswa kwexabiso elijikelezayo kukuqinisekisa ukuba utshintsho kwimirhumo yokucubungula ihambelana nexabiso le-zinc.Imarike yasekhaya ikakhulu isebenzisa indlela yokukhupha ixabiso elimiselweyo kwixabiso le-zinc ukumisela ixabiso lokugxila okanye ukuthethathethana ukumisela ixabiso le-zinc ore.
