Environmental impact of mining and beneficiation of copper
The mining and beneficiation process consumes a lot of energy and power (Hong et al. 2018), and produces crushed stones made of unwanted minerals, and a mixture of processing fluids from mining and beneficiation processes (Beylot and Villeneuve 2017), thus contributing to severe environment problems, especially for marine fauna and flora Understanding how energy is consumed in mining will give LCA assessors a better understanding of how to evaluate the energy consumption in mining versus energy consumption in recycling at stage 1. Designers need to assess product and process for mining taking into account reduction in energy use and carbon emissions.Energy Consumption in Mining Comminution ScienceDirect
