Copper production & environmental impact
The copper-bearing solution, from the solvent extraction operations, is plated into pure copper cathodes using a process called solution exchange electrowinning (SX-EW). Stainless steel blanks are added to the plating tanks to act as cathodes and copper is plated onto them by electro-chemical deposition.
Rock-to-Metal Ratio: A Foundational Metric for …
The quantity of ore mined and waste rock (i.e., overburden or barren rock) removed to produce a refined unit of a mineral commodity, its rock-to-metal ratio (RMR), is an important metric for understanding mine wastes and environmental burdens. In this analysis, we provide a comprehensive examination of RMRs for 25 commodities for …

Biodiversity conservation threatened by global mining wastes
For copper, which makes up 46% of the global tailings volume, the total amount of tailings and waste rock predicted over 2020–2050 is 858 Gt (ref. 37). Further, due to the decrease in lithium ...
Global copper smelting surges in January, satellite data shows
Global copper smelting activity powered to a 13-month peak in January as operations in China ramped up ahead of seasonal construction demand, data from satellite surveillance of copper plants showed.
(PDF) Decreasing Ore Grades in Global Metallic Mining: A Theoretical
The ore grade has been identified as a good indicator of the quality of mineral deposits and of the decrease of quality over time [30, 35] (although many other factors come into play, such as rock ...
The Ore Grade and Depth Influence on Copper Energy Inputs
with extraction energy usage (E) in MJ per kg concentrate copper based on the depth D of mining and ore grade (G) in percentage of copper per mass of ore. The parameter (gamma) now captures the joint effects of both depth and ore grade differences per mine. The equations can be used for total energy inputs or to assert the effect of …
