Use of copper mine tailing in concrete: strength
The increasing use of copper and its allied materials across many industries is ramping up copper mining activities in many countries, and proper management and disposal of huge volumes of copper mine tailings arising thereof is a huge challenge. Sungun mine is the biggest open-cast copper mine in the northwest of Iran. concrete mixtures were prepared by replacing cement with 0–30% of copper mine tailing. The specimens were tested to determine the mechanical and durability performance of concrete mixtures. Furthermore, the microstructure of concrete mixtures was also evaluated using scanning electron microscopy. Results not only revealed that these Use of copper mine tailing in concrete: strength

Environmental impact of mining and beneficiation of copper
China is a major producer of copper concentrate as its smelting capacity continues to expand dramatically. The present study analyzes the life cycle environmental impact of copper concentrate production, along with selection of a typical copper sulphate mine in China. Life cycle assessment (LCA) was conducted using SimaPro with ReCiPe The mining industry has faced significant challenges to maintaining copper production technically, economically, and environmentally viable. Some of the major limitations that must be overcome in the coming years are the copper ore grade decline due to its intense exploitation, the increasing requirements for environmental protection, and Chemical Composition Data of the Main Stages of Copper

Mine tailings-based geopolymers: A comprehensive review
The specific surface area of mine tailings, which ranges between 0.5 and 7.3 m 2 /g and is impacted by the distribution and particle shape, is measured [ 142 ]. The bulk density of mine tailings in the bulk state ranges from 1.81 to 1.93 t/m 3, with 1.81 t/m 3 being the average value.This paper presents the feasibility of incorporating copper mine tailings (MT) as a partial substitute for cement in the development of concrete. The copper mine tailings used for this study have been accumulating for several decades at the tailings dump of Hindustan Copper Ltd. at Khetri, Rajasthan. Hence, alternative uses of MT need to be Stabilization characteristics of copper mine tailings through
