Mufekitori yekugadzira zvicherwa, danho rekukuya ndiro dunhu guru rine mari yakawanda uye simba rinoshandiswa. Danho rekukuya rinodzora shanduko yezviyo mukuyerera kwese kwekugadzirisa zvicherwa, izvo zvine simba guru pahuwandu hwekudzoreredza uye huwandu hwekugadzirwa. Saka, inyaya yakatarisana nekuderedza mitengo uye kuvandudza huwandu hwekugadzirwa pasi peimwe chiyero chekukuya.
Kune mhando mbiri dzenzira yekukuya, yekukuya yakavhurika uye yekukuya yakavharika. Ndezvipi zvinonyanya kukosha panzira mbiri idzi dzekukuya? Ndeipi nzira yekukuya inogona kuita kuti kushandiswa kwayo kuve kwakasimba uye kuwedzera mwero wekugadzirwa? Mundima dzinotevera, tichapindura mibvunzo iyi.
Zvakanakira nzira mbiri dzekukuya
Kugaya kwesekitori rinovhura zvinoreva kuti, pakushanda kwekugaya, zvinhu zvinoiswa mugayo zvoburitswa mushure mekugaya, zvakananga mugayo rinotevera kana maitiro anotevera.
Zvakanakira kugayiwa kwemagetsi ari kuvhura dunhu nderekuti zviri nyore kugadzira zvinhu uye mari shoma yekudyara. Asiwo zvakanakira izvi ndezvekuti kugadzirwa kwezvinhu kwakaderera uye kushandiswa kwesimba rakawanda.
Kugaya kwesekitori yakavharwa kunoreva kuti, mukugaya, zvinhu zvinoiswa muguyo kuti zvigovaniswe mushure mekugaya, uye simbi isina kukodzera inodzoserwa kuchigayo kuti igogayiwezve, uye simbi yakakodzera inotumirwa padanho rinotevera.
Zvakanakira zvikuru zvekushandisa closed circuit-grinding imhando yekupwanya inoshanda zvakanyanya, uye mhando yekugadzira yakakwira. Munguva imwe chete, closed-circuit ine huwandu hwakakura hwekugadzira. Zvisinei, dambudziko nderekuti kufamba kwekugadzirwa kweclosed-circuit kwakaoma, uye kunodhura kupfuura kupwanya open-circuit.
Zvinhu zvisingaenderane nezvinodiwa zvinogayiwa kakawanda muchikamu chekukuya chakavharwa kusvika pasvika saizi yezvidimbu zvakakodzera. Pakukuya, zvicherwa zvakawanda zvinogona kutakurwa mumidziyo yekukuya, kuitira kuti simba remuchina webhora rigone kushandiswa zvakanyanya sezvinobvira, kuvandudza mashandiro emidziyo yekukuya, kuitira kuti mashandiro emidziyo yekukuya ave nani.
Midziyo yenzira mbiri dzekukuya
Mukusarudza michina yekukuya, chigayo chebhora hachina kugona kudzora saizi yezvikamu. Kune zviyo zvakanaka zvakagadziriswa uye zviyo zvisina kukwana mudhiraivha yematombo, izvo zvisina kukodzera michina yekukuya yakavhurika. Chigayo cheRob chakasiyana, kuvapo kwematanda esimbi pakati pebhuroko gobvu kuchatanga kwatyoka, kufamba kwematanda esimbi kwakafanana negrille yakawanda, zvinhu zvakanaka zvinogona kupfuura nemukana uri pakati pematanda esimbi. Nokudaro, chigayo chematanda chine kugona kudzora saizi yezvikamu uye chinogona kushandiswa semuchina wekukuya wakavhurika.
Kunyangwe chigayo chebhora chisina kugona kudzora saizi yezvikamu, chinogona kudzora saizi yezvikamu nerubatsiro rwemidziyo yekupatsanura. Chigayo chinoburitsa matombo mumidziyo yekupatsanura. Zvinhu zvakanaka zvinopinda muchikamu chinotevera kuburikidza nekugaya-kupatsanura. Naizvozvo, kugaya zvinhu zvisina kukwana zvinogona kupfuura nemuchigayo kakawanda, zvinofanira kukuyiwa kusvika pahukuru hwezvikamu zvakakodzera zvinogona kuburitswa nemidziyo yekupatsanura. Hapana muganho wemidziyo yekugaya inogona kusarudzwa muchikamu chekugaya chakavharwa.
Kushandiswa kwenzira mbiri dzekugaya
Zvichienderana nemhando dzakasiyana dzezvicherwa, hunhu, uye zvinodiwa zvakasiyana pakuyerera kwekugadzirwa, zvinodiwa pakukuya zvakapfava zvakasiyana. Mamiriro ezvinhu zvezvinhu zvine maumbirwo akasiyana zvinosvika padanho rakakodzera rekupatsanurwa haana kufananawo.
Mukugaya kwesekete rakavharwa, zvinhu zvinodzoserwa kumidziyo yekukuya zvinenge zvakakodzera. Kungogayazve zvishoma chete kunogona kuva chigadzirwa chakakodzera, uye kuwedzera kwezvinhu mugayo, zvinhu kuburikidza negayo nekukurumidza, nguva yekukuya ipfupi. Naizvozvo, kugaya kwesekete rakavharwa kune hunhu hwekubudirira kwakanyanya, mwero wekureruka kwekupwanya zvakanyanya, kupararira kwakanaka uye kwakafanana kwehukuru hwezvikamu. Kazhinji, chirimwa cheflotation nechirimwa chekuparadzanisa magnetic zvinonyanya kushandisa maitiro ekugaya kwesekete rakavharwa.
Kugaya kwesimbi kwakavhurika kwakakodzera kugaya kwekutanga. Zvinhu zvinoburitswa kubva kune imwe chikamu chemuchina wetsvimbo zvinopinda mune mimwe michina yekugaya uye zvinozogayiwa zvakanaka (zvakanaka). Nenzira iyi, chikamu chekutanga chemuchina wetsvimbo chine chiyero chidiki chekupwanya uye kugona kwakakwirira kwekugadzira, uye maitiro acho ari nyore.
Muchidimbu, zvinogona kuonekwa kuti kusarudzwa kwenzira yekukuya kwakaoma, izvo zvinoda kutariswa muzvinhu zvakawanda zvakaita sezvivakwa, mari yekudyara, uye maitiro etekinoroji. Zvinokurudzirwa kuti varidzi vemigodhi vabvunze vagadziri vemichina yekugadzirisa vane hunyanzvi hwekugadzira migodhi kudzivirira kurasikirwa nemari.
