why have new methods using bacteria fungi and plants to

it's too expensive to extract copper from land using traditional method because the quarrying and heating of the metal would result in an energy expenditure that would make mining copper

copper recycling and sustainability - benefits of recycling

conservation of copper ore to date only about 12% of known copper resources have been mined. however copper ore is a finite resource and it makes sense to conserve ore by recycling. economics it is cheaper to recycle old copper than to mine and extract new copper. recycled copper is worth up to 90% of the cost of the original copper.

of using copper ore mining -

copper mining. from ore to copper. the copper is recovered by electrolytic refining. advantages of this process are: much less energy is use than in traditional mining no waste gases are given off it can be used on ores with as little as 0.1% copper for this reason leaching extraction is growing in importance. marketing system

copper leaching method

a siliceous oxidized copper ore carrying from 1.5 to 2.0 per cent metal may be profitably leached under favorable conditions; there are no other metallurgical means known for commercially handling ore of that character and grade. copper leaching practices. for centuries small amounts of copper have been recovered from acid mine-drainage waters.

types of copper deposits in the world | inn

copper production figures can change rapidly but in the 2018 financial year escondida’s total production reached 1213 kilotonnes. the mine has processed more than 2 billion tonnes of ore

how to locate copper deposits | sciencing

geologists employ many techniques to locate copper deposits from testing the components of ore to studying land features to determine probable locations for a copper deposit. the process is not as easy as it once was in part because environmental regulations prevent exploratory digs deep in the earth. as a result

how does copper ore mining affect the environment - answers

mining copper ore affects the environment in many negative ways. firstly it uses land so animals and plants are usually moved or plowed over. this …

recovery of copper by solution mining methods

2 recovery of copper by solution mining methods solution mining replicates the natural process of oxidation and reduction described above. dilute acidic solutions are introduced to the copper-bearing ores causing dissolution of soluble copper minerals (table 1) remaining in the leached cap and underlying enrichment blanket.
