General ruzivo nezve ore mamakisi
Chiyero chesimbi chinoreva zviri mukati mezvinhu zvinobatsira musimbi.Kazhinji inoratidzwa muhuwandu muzana (%).Nekuda kwemhando dzakasiyana dzemaminerari, nzira dzekuratidza ore giredhi zvakare dzakasiyana.Mazhinji masimbi esimbi, akadai sesimbi, mhangura, lead, zingi uye mamwe ores, anoratidzirwa nehukuru muzana hwesimbi element yezvinhu;giredhi yemamwe masimbi esimbi inoratidzwa nehuwandu hwemazana emaokisi avo, akadai seWO3, V2O5, nezvimwewo;Iyo giredhi yeakawanda asiri-metallic mineral raw materials inoratidzwa nehuwandu hwehuwandu hwemaminerari anobatsira kana makomisheni, senge mica, asbestos, potashi, alunite, nezvimwewo;giredhi resimbi yakakosha (segoridhe, platinamu) ores rinowanzo kuratidzwa mu g/t ;Giredhi remadhayamondi ekutanga rinoratidzwa mumt/t (kana carat/ton, yakanyorwa se ct/t);giredhi rekuisa ore rinowanzo kuratidzwa mumagiramu pa cubic centimita kana kilogiramu pa cubic mita.
Iko kukosha kwekushandisa kweore kune hukama zvakanyanya negiredhi rayo.Ore inogona kupatsanurwa kuita simbi yakapfuma uye isina kunaka zvichienderana negiredhi.Semuyenzaniso, kana simbi ine giredhi rinopfuura 50% inonzi ore yakapfuma, uye kana giredhi iri ringangoita 30%, inodaidzwa kunzi dombo rakashata.Pasi pemamwe mamiriro ehunyanzvi uye ehupfumi, giredhi reindasitiri yeore yakakosha mugodhi rinowanzo kutsanangurwa, kureva, iro giredhi remaindasitiri.Mitemo yaro yakanyatsoenderana nehukuru hwedhipoziti, ore mhando, kushandiswa kwakazara, kunyunguduka uye kugadzira tekinoroji, etc. Semuenzaniso, ore yemhangura inogona kucherwa kana ikasvika 5% kana zvishoma, uye goridhe retsinga rinosvika 1 kusvika 5 gramu / ton.
Indasitiri giredhi inoreva izvo zvinobatsira izvo zvine mabhenefiti ehupfumi (zvinogona kuvimbisa kudzoserwa kwemitengo yakasiyana senge migodhi, yekufambisa, kugadzirisa uye kushandiswa) mune yakapihwa bhuroka reimwe ore yekugadzira matura mupurojekiti imwechete (sekuchera kana kuchera. )Iyo yakaderera pakati peavhareji yechikamu.Inoshandiswa kuona giredhi rinogona kudzoserwa mune zveupfumi kana giredhi rakadzikama, kureva kuti, giredhi apo kukosha kwemari yesimbi yakacherwa yakaenzana nemitengo yese yekuisa uye purofiti yemugodhi iri zero.Indasitiri giredhi inogara ichichinja nekuvandudzwa kwehupfumi uye hunyanzvi mamiriro uye chiyero chekudiwa.Semuenzaniso, kubva muzana ramakore rechi 19 kusvika nhasi uno (2011), giredhi remaindasitiri emigodhi yemhangura radzika kubva pa10% kuenda pa0.3%, uye kunyangwe giredhi remaindasitiri emamwe mahombe akavhurika emhangura emhangura anogona kudonha kusvika pa0.2%.Pamusoro pezvo, mamakisi eindasitiri ane zviyero zvakasiyana zvemhando dzakasiyana dzemamineral deposits.
