“…This scenario will promote the use of renewable energy sources, such as solar, wind, and geothermal energy [11]. In this sense, the future projection based on solar and storage technologies should be highlighted, as in the cases of electrical energy storage (EES) for copper operations, photo-voltaic electricity (PV) in copper electrowinning and solar-thermal technologies, and most notably, concentrated solar power (CSP) for copper mining operations [12,13]. When considering, for example, the world's largest copper producers, such as Chile (Escondida, El Teniente), Peru (Cerro Verde II, Quellaveco), China (Zijinshan gold-copper mine), United States (Morenci), and Australia (Olympic Dam), it can be seen that in some countries, coincidentally, industrial areas have high levels of average irradiance, which in some cases are far above 2000 kWh•m −2 year −1 [14,15].…”

The mining industry is facing emerging challenges as a result of the increase in energy consumption and environmental demands. These facts have promoted the use of renewable energy sources, such as wind, geothermal and, mainly, solar energy. This paper discusses the role of solar energy (UV-VIS-NIR) in leaching processes, evaluating its potential application in metal extraction from sulfide minerals, based on photochemical mechanisms that promote the regeneration of ferric iron or the so called ferrous iron cycling. The present paper discusses the possibility that ultraviolet, visible light and near infrared irradiation (e.g., sunlight provided) can assist the leaching processes in two main ways: by the oxidation of sulfide minerals through in-situ generated Fenton-like reactions, and by the photochemical activation of semiconductor minerals that contain transition metals (Fe, Cu, and Cr, among others). Thus, this paper provides theoretical support to move towards the future application of photoleaching, which consist of a leaching process assisted by UV, VIS, and NIR irradiation. This technology can be considered a promising mineral processing route, using direct photochemical solar energy that can reduce the energy consumption (electricity, fuels) and the environmental impact, opening an opportunity for an alternative method of metal extraction from sulfide ores.

Undoubtedly, metals are the basis of the sustainable development of all human societies. In the last century, the role of copper, as the third most widely used metal, after steel and aluminum, has been crucial. Copper is a recyclable metal. It has many applications such as industrial electricity, plumping, wiring, electronic equipment, transportation, and infrastructure. Today, with the growth of the industry in societies, the demand for copper has increased. This motivated us to study its supply chain network design firstly. To the best of our knowledge, there is no research reported about copper supply chain network design. This paper aims to maximize the profit of the copper closed-loop supply chain. We formulate this network design problem as a Mixed Integer Programming model. The model is considered as single-objective and multi-product. The exact solution of the model is found by using GAMS software. Sensitivity analysis results provide useful results that managers can use them in decisions.

“…Although many of the reported microgrid applications concern research testbeds or rural electrification [20], [32], [33], the academic community is currently discussing not only RES insertion to supply whole plants such as mines (EMS approach), but also sub-process optimization according to the energy available in off-grid scenarios (DSM approach) [11]. In contrast, there are not detailed reports of microgrids in heavy industries.…”

“…Meanwhile, the DSM optimizes the load profile in accordance with the energy available by managing process set points or rescheduling flexible loads. However, the latter is not always feasible in mining; therefore, in this case the power profile is understood as a hard constraint, which must be satisfied in a business-as-usual approach [11].…”

The transition from fossil fuels to renewable energies as power sources in the heavy industries is one of the main climate change mitigation strategies. The carbon footprint in mining is related to its inherent extraction process, its high demand of electric power and water ,and the use of diesel. However, considering its particular power requirements, the integration of microgrids throughout the whole control hierarchy of mining industry is an emergent topic. This paper provides an overview of the opportunities and challenges derived from the synergy between microgrids and the mining industry. Bidirectional and optimal power flow, as well as the integration of power quality have been identified as microgrid features that could potentially enhance mining processes. Recommendations pertaining to the technological transition and the improvement of energy issues in mining environments are also highlighted in this work. INDEX TERMS Mining industry, microgrids, power quality, energy management system, renewable energies.
