General ruzivo nezve ore mamakisi
Giredhi re ore rinoreva nezviri zvinobatsira mune ore. Kazhinji inoratidzwa muhuwandu muzana (%). Nekuda kwemhando dzakasiyana dzemaminerari, nzira dzekuratidza giredhi reOre zvakare dzakasiyana. Mazhinji emesimbi eires, akadai sedare, mhangura, kutungamira, zinc uye mamwe maOres, anoratidzwa nehuwandu hwehuwandu hwesimbi yepamhepo yezvinhu; Giredhi reimwe maOres esimbi rinoratidzwa nehuwandu hwehuwandu hwehukuru hwavo, hwakadai saWo3, v2o5, nezvimwe.; Giredhi rezvisikwa zvisina-metiric mineral dzimba rakatsvuka rinoratidzwa nehuwandu hwehuwandu hwepazasi hwemaminerari dzinobatsira kana mica, asbestos, potash, etc.; Giredhi resimbi rinokosha (rakadai segoridhe, maPlatinum) maPlatin anowanzo kuratidzwa muG / t; giredhi redhaimani redyimani rinoratidzwa muMt / t (kana carar / ton, rakanyorwa seCT / T); Giredhi rePlacer Ore rinowanzotaridzirwa muGraims pa cubic centimeter kana kilogiramu paubhiti metres.
Iko kukosha kwekushandisa kweOre kwakanyatsoenderana negiredhi rayo. Ore inogona kukamurwa kuva yakapfuma ore uye murombo ore zvichienderana negiredhi. Semuenzaniso, kana iron ore ine giredhi reanopfuura 50%, inonzi yakapfuma ore, uye kana giredhi racho riri anenge makumi matatu muzana, inonzi murombo ore. Pasi pane mamwe maitiro ehunyanzvi uye ehupfumi, giredhi reindasitiri reOre rakakodzera kuwanda rinowanzo tsanangurwa, kureva kuti, iyo madiki maindasitiri giredhi. Mitemo yayo inoenderana neyakaenzana neiyo dhipoziti, Ore mhando, kunyungudika uye kugadzirisa tekinoroji, yegoridhe kana zvishoma, uye vein ndarama inosvika 1 kusvika ku5 Grams / ton.
Maindasitiri giredhi anoreva zvinhu zvinobatsira zvine makomborero ehupfumi (anogona kuvimbisa kudzorera kwemari dzakasiyana siyana senge mangozi, mune yakapihwa) mune yakapihwa ore fomu yekugadzira mune imwe chete projekiti (yakadai sekukweva kana kurambidza ). Iyo yakaderera pakati pezvinyorwa zvechikamu. Izvo zvinoshandiswa kuona nezvehupfumi kupora kana giredhi rehupfumi, ndiko kuti, iyo giredhi kana kukosha kwemari yeiyo mineed ore yakaenzana nemitengo yese yekuisa uye purofiti yemugodhi ndeye zero. Giredhi reindasitiri rinogara richichinja nekuvandudzwa kwehupfumi uye technical mamiriro uye huwandu hwekuda. Semuenzaniso, kubva muzana ramakore re19 riripo (2011), giredhi reindasitiri remaminitsi emicheka rakadonha kubva pagumi kusvika ku1.3%, uye kunyange giredhi reindasitiri reimwe rakavhurika-pit mhangura racho rinogona kudonha ku0. 2%. Mukuwedzera, mamakisi emumaindasitiri ane mwero akasiyana emhando dzakasiyana dzemaminerari deposits.
