Potencial de utilização de barramento de água para suprir demandas do processo de beneficiamento em atividade mineira

Abstract

Socioeconomic and industrial development over the years has led to unbridled consumption of this element. Mining, a process that causes large impacts, has a great need for water, such as a mining company, in the Três Estradas Project, located in the city of Lavras do Sul, RS, where there is a Phosphate beneficiation plant, which leads to a great importance of the hydrological study of this area. Thus, in this work, a pluviometric quantitative analysis was performed in the study area, assuming the construction of a bus, in order to verify the supply or not of the water demand for the enterprise. For this, a calculation was made of the monthly rainfall volume in the region and then the water difference between supply and demand of the company was calculated using the Australian Practical Method (ABNT NBR 15527/2007). With this, it is concluded that the demand for water will be much higher than supply, necessitating other solutions for the company's need.
