Bioleaching and Phytomining Extraction of Copper by

Dec 10, 2015· This is one way of extracting copper from low grade ores- which are less than 1% copper. Relatively, it is a cheap way of extracting copper. Select plants will absorb copper compounds through their roots, and the compounds become concentrated in the plant. When the plants are burned, the ash that is produced contains these copper compounds.

purification of copper by electrolysis metal extraction

Finite reserves of copper ores are becoming scarce and new ways of extracting copper from low-grade ores include phytomining, and bioleaching. Low grade ores only contain small concentrations of copper and would not normally be considered economic to mine and process, as would waste material from processing high grade copper ores.

Phytomining & Bioleaching By Lucy Patterson (Sophie's Sibling)

Simply put,PHYTOMINING is a form of EXTRACTION. What does it do? It extracts COPPER COMPOUNDS from the ASH of a burnt plant. By burning . the plant, the oxygen is reacting with copper. This makes COPPER OXIDE . The ash which contains the copper compound is then put through ELECTROLYSIS. How do these compounds get into the plant?

Innovations in Copper: Mining & Extraction: Producing

Prior to the development of the solvent extraction-electrowinning (SX/EW) process in 1959 (see Copper the Green Metal), the only way to recover copper from an acid solution was by a process called cementation. In this process, copper was in effect "traded" for iron by contacting the copper-bearing solution with scrap iron.

Copper extraction Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).
