Mukuita kucherwa nekushandiswa kwezvicherwa zviwanikwa, hazvidzivisiki kugadzira huwandu hwakawanda hwemarara. Waste rock imhando yemarara akasimba, kusanganisira hurungudo, slag, tsvina ore, tailings, etc. Kana marara aya asina kuraswa zvakanaka, vachava netapuro yakakomba pamhoteredzo.

Kutarisirwa kwemarara mumigodhi chikamu chakakosha chekucherwa kwezvicherwa zvezvicherwa. Inosanganisira kurapwa kunoshanda uye kuraswa kwemarara akasiyana-siyana anogadzirwa panguva yekuchera migodhi, nokudaro kuderedza kusvibiswa uye kukanganisa kwezvakatipoteredza. Nekuvandudzwa kwekuziva kwezvakatipoteredza uye kushandiswa kwakasimba kwemitemo yakakodzera nemitemo, kutariswa kwemarara mumigodhi kwave chimwe chezvinhu zvakakosha zvekusimudzira indasitiri yezvicherwa.

BB fetereza, zita rizere fetireza yekusanganisa yakawanda. Zvakare, Fetereza yeBB inonyanya kuumbwa nezviviri kana zvitatu zvenitrogen, phosphorus uye potassium. Besides, Fetereza yeBB inogadzirwa nekusanganisa akati wandei mafetireza ega kana kuti mafetireza emukomboni mune imwe chikamu. Chinhu chayo chikuru ndechekuti zvinongedzo uye zviyero zvinogona kuchinjika zvinogadziriswa zvinoenderana nezvirimwa zvakasiyana uye mamiriro evhu.. Saizvozvo, Fetereza yeBB inofarirwa zvikuru mukugadzirwa kwekurima nekuti inokwanisa kunyatsozadzisa zvinovaka muviri zvinodiwa pazvirimwa zvakasiyana..

Carbon dema, ihupfu nhema kana kuti chimedu chinonyanya kuumbwa nemaatomu ecarbon. Nekuda kweiyo yakasarudzika yemuviri uye makemikari zvinhu, inoita basa rakakosha mumaindasitiri mazhinji. Zvakananga, inoshandiswa zvakanyanya murubha, mapurasitiki, inks, coatings, electronic components, makemikari edehwe, mabhatiri akaoma uye mamwe akawanda maindasitiri. Carbon black imhando yefine carbon particles, iyo inogadzirwa nekupisa kana pyrolyzing carbonaceous zvinhu pasina oxygen. Chaizvoizvo, ine maitiro ekuita zvakanaka, pigmentation uye kusimbisa zvivakwa. Chii chimwe, kabhoni dema haigone kungovandudza simba remagetsi uye hupenyu hwebasa rezvigadzirwa, asiwo inopa zviri nani ruvara uye kupenya.
