Renewable Source-Based Water Pumping Electrification in Mines: Current technologies and future trends
Water pumping is an essential function in diverse industrial sectors, including manufacturing, mining, agriculture, oil and gas, and chemical processing. The global energy consumption of pumps is approximately 15%, and in the particular case of the mining industry, pumps can represent up to a 24% of the average consumption of energy, as shown in Figure 1. The use of water in the mining industry has some distinctive features compared to other industrial applications. Most of the large mines are located in arid or semiarid regions where water is scarce and there are few competing users, such as agriculture and towns. A mine itself could be the largest water user in the sector. Therefore, to cope with water scarcity, it could be necessary to transport the water large distances to supply a mine. In general, a mine requires water in several processes, some of them critical, then, pumping is crucial to ensure the continuous operation of the industry. On the other hand, regarding the geographical location, as mines could operate in windy regions and/or regions rich in solar irradiation, e.g., copper mines in Chile and Australia, or chromite mines in South Africa, the use of renewable energies to supply pumps is an attractive option. In this article, we explore pumping requirements in the mining industry, its possibilities for electrification based on renewables sources, the limitations, and the prospections of this relevant industrial sector.
期刊介绍:
ACS Applied Bio Materials is an interdisciplinary journal publishing original research covering all aspects of biomaterials and biointerfaces including and beyond the traditional biosensing, biomedical and therapeutic applications.
The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates knowledge in the areas of materials, engineering, physics, bioscience, and chemistry into important bio applications. The journal is specifically interested in work that addresses the relationship between structure and function and assesses the stability and degradation of materials under relevant environmental and biological conditions.
