Process of extracting copper using plants 9 of 15 What does Bleaching mean? Process of extracting copper using plants 10 of 15 What three ares do humans process finite resources from? Earth, oceans and the atmosphere 11 of 15 What are the four stages in the treatment of sewage? (1) Filtration(Screening) (2) Sedimentation (3) sludge is dried and anaerobically digested (4) Effluent is aerobically digested 12 of 15 What types od ores can phytomining and bleaching be used on? Low-grade ores 13 of 15 How does phytomining extract metals? Plants absorb the metal compounds. They can then be collected and burnt with the ash left behind being pieces of metal 14 of 15 How does bioleaching extract metals? The bacteria eats the low-grade and absorbs the metal. These can then be processed leaving metals behind 15 of 15
