The State of Pará became the largest mineral producer in Brazil in 2019, standing out in the first place in the production of iron ore, copper, bauxite and kaolin. The generation of waste is an inherent part of any production process. In the case of mining, in recent years, due to the increase in demand for mineral inputs, there has been a great growth in its activities. This resulted in the equally growing generation of mining tailings. The need to give sustainable destination to mining tailings is urgent, and the economic use of these materials emerges as an alternative to deposition in structures such as piles and dams. The aim of this work was to present an overview of studies on the use of mining tailings in the State of Pará from 2010 to 2020. For this, the methodology used was the systematic review and bibliometric analysis of the works obtained. As a result, it was possible to observe that there was an increasing number of published works on the subject during the period studied. The largest number of works was published in the period 2015 – 2020 (45) with practically twice as many publications from the period 2010 – 2014 (19). Kaolin was the mineral that presented the highest number of published works on the use of the waste generated from its processing (42.2%). The synthesis of products from the tailings, especially the synthesis of zeolites from the tailings of kaolin processing, was the main area of application of the works selected in the research, followed by the area of Civil Construction (red ceramics, aggregates, mortars, geopolymer). UFPA was the research institution that most published works on the subject of waste use in Pará during the period studied (56.3%). With this research, it was possible to draw an overview of studies on the use of mining tailings in the State of Pará, delivering a structured synthesis of scientific development during the period from 2010 to 2020, to contribute to researchers who wish to work with the aforementioned topic
