WebProcess of phytomining. 1) growing the plants on the area of the ore. 2)the plants then absorb the metal compounds. 3) the plants are harvested and burned. 4) the ash contains a high concentration of the metal compound. process of bioleaching. 1) bacteria is mixed with the low grade ore. 2)the bacteria carries out chemical reactions and ... WebSep 1, 1998 · Phytomining for metals other than nickel. There are practical limits to phytomining[13]. The main variables that control its economic feasibility are: the metal price, the plant biomass, and the highest achievable metal content of the plant (Table 2). Metal values range from about $15 000 000 t − 1 for platinum to about $600 t − 1 for lead.

WebBioleaching. Some bacteria can live by using the energy of the bond between sulfur and copper. This separates the metal from the ore and is called bioleaching. It has the advantage that it is very energy efficient typically using only 30% to 50 % of the traditional method. It has the disadvantage that it is very slow. Phytomining.
