In the southern and central regions of Peru, part of the social and environmental conflicts are generated in the final phase of mining operations, when the mine closure management process is carried out, bringing with it environmental liabilities. Given the need to create solutions to social and environmental problems, this research work aims to incorporate residual diatomaceous earth in the cover design of the closure plan for dump 28 - Compañía Minera Antapaccay Espinar, Cusco. The methodology was based on the extraction of mining soil from dump 28, under the methodological guide for the sampling of contaminated soils of the Ministry of the Environment (MINAM); the samples were transferred to the laboratory for sieving and homogenization, in the same way, the sampling of residual diatomaceous earth extracted from the Union of Peruvian Breweries Backus and Johnston S.A.A of the department of Cusco was carried out, the samples were transferred to the plant located in the district from Lamay, Calca, Cusco, which is operated by an EO-RS company for its treatment and final obtaining in pulverized form, then they were taken to the laboratory. The soil sample from dump 28 was divided into 21 samples (trays) of 1kg soil each, seven residual diatomaceous earth dosages were made (1g, 4g, 7g, 10g, 13g, 16g and 19g), and the diatomaceous earth dosages residual were subjected to a dissolution process at three different dosages of distilled water (100ml, 150ml and 200ml) before being incorporated into the soil of dump 28. The parameters evaluated were pH, EC, N, P, K, Ca2+, Mg2+, K+, Na+, Fe, Cu, Mn, Zn, Cd, Cr, Pb, TOC, and C/N. The results were analyzed under a Student's T statistical design for related samples, using the SPSS statistical package. The laboratory results indicate that there were changes in the chemical and physical characteristics of the dump soil after adding residual diatomaceous earth. Showing a high significance level of 99% in the following parameters of pH, EC, N, P, K+, Ca2+, K, Na+, Cu, Mn, Zn, Cd, and Cr. However, no significant changes were shown in the Mg2+, Fe, and Pb parameters.
