Ma carbon a Ed amagwiritsidwa ntchito kubweza golide kuchokera ku cyanide solutions, zomwe zimazunguliridwa ndi miyala yokhala ndi golide.Fakitale yathu imatha kupereka ma carbon ochuluka opangira migodi ya golide, yomwe kuyesedwa kodziyimira pawokha, ndi mabungwe otsogola apamwamba, kwawonetsa kuchita bwino kwambiri.
Chipolopolo cha coconut activated carbon chimapangidwa ndi chipolopolo cha kokonati chapamwamba kwambiri monga zinthu zopangira, kuwombera ndi njira yakuthupi, chimakhala ndi zinthu zabwino zotsatsa komanso katundu wosavala, mphamvu zambiri, nthawi yayitali.Mitundu ya carbon activated imagwiritsidwa ntchito kwambiri mu Carbon-in-Pulp ndi Carbon-in-Leach pobwezeretsanso golide kuchokera pazakudya zoduliridwa komanso m'mabwalo a Carbon-in-Column komwe mayankho omveka bwino okhala ndi golide amathandizidwa.
Zogulitsazi zimadziwika chifukwa cha kuchuluka kwa golide komanso kutsika kwa golide, kukana kwawo kumakanika, kutsika kwa mapulateleti, kukhazikika kwa tinthu tating'onoting'ono komanso zinthu zocheperako.
