Is Insitu Leaching The Green Mining Future

Is Insitu Leaching The Green Mining Future May 07, 2019 I recently came across an insitu leaching website, called BIOMore. This was an initiative sponsored by the EU that looked at insitu leaching technology for metal recovery. Environmental issues associated with mining in Europe, particularly open pit mining, raised concerns about how ore bodies in the EU might be developed in the future.May 07, 2019 I recently came across an insitu leaching website, called BIOMore. This was an initiative sponsored by the EU that looked at insitu leaching technology for metal recovery. Environmental issues associated with mining in Europe, particularly open pit mining, raised concerns about how ore bodies in the EU might be developed in the future.The technology allows for the use of leaching systems on primary sulphides. These systems have a far superior environmental profile compared to traditional extraction methods. The environmental benefits include improved resource maximisation, significantly lower emissions, and lower water usage.
