Ulwazi oluphangaleleyo ngamabakala e-ore
Umgangatho wentsimbi ekrwada ubhekiselele kumxholo wezinto eziluncedo kwintsimbi ekrwada.Ibonakaliswa ngokwepesenti yobuninzi (%).Ngenxa yeentlobo ezahlukeneyo zeeminerali, iindlela zokubonisa ibakala le-ore nazo zahlukile.Uninzi lwentsimbi, njengentsimbi, ubhedu, ilothe, i-zinc kunye nezinye iintsimbi, zibonakaliswa yipesenti yobuninzi bomxholo wesinyithi;ibakala lezinye iintsimbi zetsimbi libonakaliswa yipesenti yobuninzi bee-oxides zabo, ezifana ne-WO3, i-V2O5, njl.Umgangatho wezinto ezininzi ezingezizo ezentsimbi zibonakaliswa yipesenti yobuninzi beeminerali eziluncedo okanye iikhompawundi, ezinjengemica, iasbestos, ipotash, ialunite, njl.;ibakala lentsimbi enqabileyo (efana negolide, iplatinam) ore libonakaliswa g/t ;Ibakala lentsimbi ekrwada esisiseko yedayimane ibonakaliswa nge-mt/t (okanye i-carat/ton, irekhodwe njenge-ct/t);ibakala le-placer ore lichazwa ngokubanzi ngeegrem nge-cubic centimeter okanye ikhilogram nge-cubic meter nganye.
Ixabiso lokusetyenziswa kwentsimbi ekrwada linxulumene ngokusondeleyo nomgangatho walo.Intsimbi ekrwada inokohlulwa ibe yintsimbi ekrwada etyebileyo kwaye intsimbi ekrwada embi ngokwebakala.Umzekelo, ukuba intsimbi inebanga elingaphezulu kwama-50%, ibizwa ngokuba yintsimbi ekrwada etyebileyo, kwaye ukuba ibakala limalunga nama-30%, kuthiwa yintsimbi ekrwada ehlwempuzekileyo.Ngaphantsi kweemeko ezithile zobugcisa kunye nezoqoqosho, ibakala loshishino lokumbiwa kwentsimbi ekrwada lidla ngokuchazwa, oko kukuthi, ubuncinci bebakala loshishino.Imimiselo yayo inxulumene ngokusondeleyo nobukhulu bediphozithi, uhlobo lwe-ore, ukusetyenziswa ngokubanzi, ukunyibilikisa kunye nobuchwepheshe bokucubungula, njl. itoni.
Umgangatho wemizi-mveliso ubhekiselele kwizinto eziluncedo ezineenzuzo zoqoqosho (ubuncinci zinokuqinisekisa imbuyekezo yeendleko ezahlukeneyo ezifana nokumbiwa kwemigodi, uthutho, ukusetyenzwa kunye nokusetyenziswa) kwibhloko enikiweyo yokugcinwa kwentsimbi ekrwada enye kwiprojekthi enye (efana nokugrumba okanye ukugrumba. ).Owona mndilili uphantsi womxholo wecandelo.Isetyenziselwa ukumisela ibakala elinokubuyiswa ngokwezoqoqosho okanye elilungeleleneyo ngokoqoqosho, oko kukuthi, ibakala xa ixabiso lengeniso yentsimbi ekrwada lilingana nazo zonke iindleko zegalelo kwaye inzuzo yemigodi inguziro.Ibakala lezoshishino lihlala litshintsha ngophuhliso lweemeko zoqoqosho kunye nobugcisa kunye neqondo lemfuno.Umzekelo, ukusuka kwinkulungwane ye-19 ukuza kuthi ga ngoku (2011), ibakala lemizi-mveliso yemigodi yobhedu lehlile ukusuka kwi-10% ukuya kwi-0.3%, kwaye nenqanaba lemizi-mveliso lezinye iidipozithi ezinkulu zobhedu ezivulekileyo zinokuhla ziye kwi-0.2%.Ukongezelela, amabakala amashishini anemigangatho eyahlukeneyo yeentlobo ezahlukeneyo zeediphozithi zamaminerali.
