In recent years the processing of mining residues and more importantly flotation tailings have been an alternative way to secure sustainable development and metal supply [[1] [2] [3]] Recycling of mining wastes results in multiple advantages including value metals recovered and environmental remediation [4] Froth flotation is a commonly used technique to
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 the need to expand
In order to comprehensively utilize iron ore tailings IOTs the possibility of using IOTs as raw materials for the preparation of cementitious composites IOTCCs was investigated and IOTCC was further applied to mine interface pollution control The mechanical properties hydration products wind erosion resistance and freeze thaw F T cycle
Metals are essential in the transition to the green technologies in low emission electric vehicles and in energy storage systems Upadhyay et al 2021 At the same time with the positive contribution to the society mining also produces significant amounts of solid waste Edraki et al 2014 belonging with millions of tons annually Wang et al 2014 to the
Mining waste contains large amounts of base Pb Cu Zn Ni and precious metals Au Pt Ag Nowadays efficient extraction of metals copper zinc needed worldwide is necessary but still limited Although the domestic processing plant equipment and processing technology has made great progress due to the characteristics of poor fine
in the risk of tailing dam failure Klohn 1997; Davis 2002; Psarropoulos and Tsompanakis 2008; Rico et al 2008; Azam and Li 2010; Ferdosi et al 2015 In fact the main concern with such tailing dams is the stability during the mining operation and after 2010 reportedatotalof198
The mineral composition of copper cobalt ores is more complex than that of copper sulfides and it is also difficult to discard tailing efficiently in primary flotation for the fine grained
Typical sulphide copper ore flowsheet process of copper mine tailings management Zheng B Characterizations of heavy metal contamination microbial community and resistance genes in a tailing of the largest copper mine in China Environ Pollut 2021;280 116947 doi / [Google Scholar] 56 Edinger E Gold
Copper tailings are the fine grained remains of copper ore produced through a series of processing techniques and belong to the by products produced during the mining process of mineral resources [1] It is characterized by a high SiO 2 content and a mineral composition dominated by quartz and silica aluminates [2] As of 2022 the production of tailings in China
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 2016 method The
copper production particularly in Chile increased significantly The failure resulted in almost immediate industry initiated changes to tailings facility construction in Chile These included • using dozers to flatten the downstream slope to about half from an angle of repose of wet sand of about horizontal to 1 vertical to about 4 to 1
In addition Turkish researchers Onal et al 2012 studied the recovery of copper cobalt nickel and magnetite from the iron ore tailing of Divriji Mine through a sequence of flotation
A copper tailing is a residue product of the flotation of sulfide minerals which contain a variety of elements that can be valorized Goryachev A ; Svetlov A ; Kompanchenko A ; Makarov D Sulfuric Acid Granulation of Copper—Nickel Ore Tailings Leaching of Copper and Nickel in the Presence of Sulfide Oxidation Activators Minerals
Copper tailing was composed of fine sand particles left after crushing and cleaning of ore which was much industrial solid waste Zhang et al 2019 There were many copper tailings in China According to relevant statistics by the end of 2013 the accumulation of copper tailings in China has reached billion tons
The rheological properties of the copper tailing sediments were determined using a rotational rheometer Anton Paar MCR 102 Austria under laminar flow conditions The copper tailing sediments were acquired from sedimentation experiments and after being allowed to settle for 1 h the upper 60 mL of the suspension was siphoned off
Within copper mining and extraction the resulting tailings usually account for a high proportion up to 99% of the mined ore IIED 2002 Submarine tailing disposal is considered to be a viable option as the tailings are not visible on land may be more stable on the ocean floor and are less likely to oxidize in the submarine environment
Tailing in context to mining is defined as the waste or non economic by product generated during mining activities processing of minerals and other materials that contain small amounts of residual valuable minerals chemicals water and heavy metals Adiansyah et al 2015 Studies indicated that the process of mineral exploitation and utilization
The water energy and material related LCI results of this Norwegian underground copper mine were benchmarked with two reference cases Table 5 one Australian underground copper ore Norgate and Haque 2010 and the other representing European copper mine operations on average underground mining 30% and open pit 70% in the latest
Copper slag flotation tailing CSFT is a by product of Cu pyro metallurgical production which accounts for more than 80 % of all Cu products produced worldwide [1] During Cu extraction molten Cu slag is generated which consists of a matrix of iron silicates Fe 2 SiO 4 metal oxides and matte droplets [1] Copper is usually recovered by froth flotation after
The mineral composition of copper cobalt ores is more complex than that of copper sulfides and it is also difficult to discard tailing efficiently in primary flotation for the fine grained disseminated of ore In this work a mineral liberation analyzer MLA was employed to study the characteristics of minerals As a significant mineralogical characteristic the liberation
Mining activity accounts for about 3% of the total country s water consumption In 2019 inland water consumption of Chilean copper mining was m 3 /s Of these 3% were consumed by smelting and refining operations 19% by mine operation and services 14% by hydrometallurgical heap leaching solvent extraction and electro winning
