Resumen:

Since the industrial revolution period, the mining industry has brought benefits for human development. Mining is a primary industry relating several operations such as exploration, extraction, milling, purification, and refining of minerals. Oil industry is an example of mining with great importance in humanity. Metal and nonmetal industries also symbolize the principal activities with great impact on human development. However, this important industry has generated environmental impacts such as soil, water, and air contamination. Heavy metals and metalloids are bioaccumulative and cause several diseases including poisoning because these elements are accumulated in soft tissues of the body. Lead, cadmium, mercury, and arsenic are examples of heavy metals that cause poisoning in humans and other living beings. Depollution of contaminated sites with heavy metals and metalloids is necessary to ensure a high quality of life; moreover, it is part of the sustainable development. For the aforementioned purpose, in this chapter the technologies for the removal of heavy metals and metalloids generated from the mining industry are considered, with emphasis on the use of natural and synthetic zeolites. The latter type of zeolites is synthesized from wastes. In addition, the comparison between both types of zeolites for the removal of these elements is reviewed to identify the challenges in this important effort. Furthermore, the footprint carbon is estimated for these processes in order to evaluate the use of natural zeolites or those synthesized from wastes. © 2021 Elsevier Inc.
