Abstract
Metallurgical processes in beneficiation plants, generate large quantities of waste called mining tailings, which are harmful to the environment and health due to the heavy metals present. These tailings are sometimes deposited in water effluents, close to mining production areas. Therefore, the purpose of the present investigation was to propose partial remediation of the exposed problem, with the use of zeolite, depositing this mineral on and under the mining tailings, carrying out 10 tests, with variation in the amount of zeolite, from 100 to 500 grams. The trials were subject to an action time of 30 days. The results obtained in the experimentation show that the test with 500 grams, placed at the bottom of the tailings, was the most efficient for the absorption of heavy metals, specifically with results of 43% in lead and 51% in arsenic, which benefits to the environment.
