·Copper mining has a devastating impact on the environment The sheer size of a copper mining operation is enough to consider harmful; however copper mining also affects environmental and human health Deforestation & Land Degradation Depending on where the ore is located copper mining can severely damage the environment through deforestation
·The authors examine oxidation of sulfide minerals in mine waste and the associated ecological problems The highest environmental hazard is produced by fine dispersed mill tailings especially where sulfide content is comparable with nonmetal content of low chemical activity In terms of some production waste accumulations in Murmansk Region it is shown
·Open pit mining or opencast mining is a surface mining technique used for large scale operations It involves extracting minerals from a pit by removing waste rock and overburden Commonly used for minerals like copper gold and iron ore requires heavy equipment such as trucks and shovels to efficiently extract the ore
Typical particle size distribution curve and electronic microscope image of mine tailings Mine tailings must be stored in a safe and controlled manner in a tailings storage facility where there is a containment dam and a reservoir area for the storage of these mining wastes [] In addition it is important to highlight that the management of water that has come into contact with the mine
·Copper occurs in nature in the form of sulphide and oxide ores salt minerals and as native copper It is the second most used non ferrous metal in industry Boulamanti and Moya 2016 According to the United States Geological Survey USGS the 2019 global annual copper extraction was about 20 million tons Fig 1 The highest annual mining capacity was recorded
·Copper mine tailings are causing great environmental concern nowadays due to their high contents of heavy metals These hazards may release to air water and soil posing great threat to the living organisms in the surroundings In the present work we profiled the heavy metal contents microbiome
·In deep metal mines seismic hazards for example rock bursts and roof collapses occur easily due to the influence of complicated geological conditions high stress environments and strong blast disturbances A microseismic MS monitoring technique was used to evaluate rock mass stability in the Hongtoushan copper mine in China The changes in the
·Mining common minerals involves managing a large mass gangue associated with moving a significant amount of waste generated during mining For example the extraction of coal lignite building materials iron and rare metals such as copper nickel or gold require drilling crushing handling of piles ore loading waste loading unloading and hauling Asif et
·Immense quantities of tailings accumulate in the form of large hills or water ponds which may cause severe problems Sometimes large tailing dumps are unstable suffer from slope instability and may cause geo hazards such as landslides Hearn 1995; Yang et al 2015 Furthermore as reservoirs of metal containing wastes copper mine tailings significantly
·However because it has been established that the environmental hazards of copper depend on the exposed surface area this cut off could also be expressed as SSA ECI 2020 A copper sphere with a density of 8 960 kg/m3 of 1 mm diameter has an SSA of mm2/mg and this value can
Longstanding mining of copper deposit in the Legnica Glogow Mining Basin LGOM area enabled to gain broad experience concerning the impact of geological and mining conditions on seismic and rockburst hazard Basing on gathered data the methods of rockburst prevention for deep copper mines were developed Methods of rockburst hazard evaluation as well as rockburst
·The harmful effects of some minerals are mostly evident from its site of occurrence process of mining post mining wastes left over and even in finished products The current review focuses to evaluate the hazardous nature of minerals cautions associated with its mining drastic effects on human health and ecosystem as an eye opener to us
Longstanding mining of copper deposit in the Legnica Glogow Mining Basin LGOM area enabled to gain broad experience concerning the impact of geological and mining conditions on seismic and rockburst hazard Basing on gathered data the methods of rockburst prevention for deep copper mines were developed Methods of rockburst hazard evaluation as well as rockburst
·Mining safety refers to practices procedures and regulations aimed at controlling and managing the various hazards associated with every step of the mining process from exploration to reclamation By taking well strategized measures to prevent accidents injuries and fatalities during operations companies can effectively safeguard the
·Copper mining essential for producing one of the most versatile and widely used metals involves significant safety and environmental risks Irwin s Safety begins with thorough risk assessments to identify and evaluate hazards specific to copper mining operations laying the groundwork for developing targeted safety strategies
·Open pit mining is applied todisseminated ore bodies or steeply dipping veins or copper iron and nearly all nonmetallic coal uranium phosphate etc It is a underground hazards Table 1 Advantages and disadvantages of open pit mining method [2 3] Figure 1
The hazards of gaseous geodynamic phenomena and rockbursts are among the most challenging to assess and classify This perception arises from both a review of the literature and an examination of available instructions and regulations in underground mining facilities The hazard of gaseous geodynamic phenomena in Polish copper ore mines only appeared in 2009
·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 compounds are most commonly used in agriculture to treat plant diseases like mildew or for water treatment and as preservatives for wood leather and fabrics WHAT HAPPENS TO COPPER WHEN IT ENTERS THE ENVIRONMENT Copper can enter the environment through releases from the mining of copper and other metals and
Copper is a metal that occurs naturally in the environment and also in plants and animals Low levels of copper are essential for maintaining good health High levels can cause harmful effects such as irritation of the nose mouth and eyes vomiting diarrhea stomach cramps nausea and even death Copper has been found in at least 906 of the 1 647 National Priority Sites
·Although mining is a cornerstone of the South African economy it generates copious amounts of dust 1 The dusts may be toxic since they may also be contaminated with various toxic this reason the prevalence and severity of occupational diseases in the mining industry depends on the ores mined the contaminants present and also on the levels
·Mining is of interest to geomorphologists because of the unique types of excavated and accumulated landforms and landscapes that are vulnerable to geomorphic hazards
·The mining sector The mining sector is pivotal to the world s economy The revenue of the top 40 global mining companies was US$656 billion in 2020 Garside 2021 The mining chemicals market is set to be worth US$38 billion by 2024 Grand View Research 2018 Most exploited commodities worldwide are iron ore coal postash and copper
·suggested to evaluate the real state of a coal burst hazard the seismological method the seismoacoustic method and the drilling method The way to solve the problem of gaseous geodynamical phenomena hazard is not yet determined Attempts have been made to introduce a classification of gaseous geodynamic hazards in copper ore mines [11]
