The recovery and concentrate grade, used simultaneously, are the most widely accepted measures of assessing metallurgical performance. Meanwhile, new challenges are being found with more complex ores around the world, a new methodology to evaluate flotation circuits more accurately is used to keep the Mineral Industry afloat in a changing world by increasing revenues. The flotation process is d...

A 5-yr study was conducted to measure the rates of recovery of fish and invertebrate communities following reclamation of a watershed impacted by an abandoned coal surface mine in Southwest Missouri. Quarterly monitoring of water quality information (pH, conductivity, and alkalinity) was conducted at 10 sites. Annual monitoring of biological (benthic invertebrate and fish community structure), ...

In this study, copper present in industrial waste water with a variety of other impurities (Fe, Mg, Al, Zn, As) was subjected for selective electrochemical recovery. The recovery conducted directly on carbon nanostructures order to create added-value products synergistically. In-depth and structural analysis showed that single/multi-walled nanotubes (CNTs) graphene composites could provide an e...
