During the last decades, waste generation has increased enormously as a result of the activities of the exploitation of resources, raising environmental concerns in communities around the world. To tackle this issue, the industry must find new ways to recycle and reduce the generation of waste in the so-called circular economy. Since 2007 EcoMetales, a Chilean company subsidiary of Codelco, has been contributing to the field of value recovery and stabilization of deleterious elements from mining waste. The EcoMetales industrial site is located in Calama, close to the Chuquicamata copper smelter and the Ministro Hales Roaster Plant, both Codelco operations. Additionally, a fully equipped metallurgical laboratory and pilot plant for assessing new technologies is located on the industrial site. An overview of the company in the processing of metallurgical residues, as well as a review of the different technologies developed for the mining sector, is presented in this keynote conference.

摘要

During the last decades, waste generation has increased enormously as a result of the activities of the exploitation of resources, raising environmental concerns in communities around the world. To tackle this issue, the industry must find new ways to recycle and reduce the generation of waste in the so-called circular economy. Since 2007 EcoMetales, a Chilean company subsidiary of Codelco, has been contributing to the field of value recovery and stabilization of deleterious elements from mining waste. The EcoMetales industrial site is located in Calama, close to the Chuquicamata copper smelter and the Ministro Hales Roaster Plant, both Codelco operations. Additionally, a fully equipped metallurgical laboratory and pilot plant for assessing new technologies is located on the industrial site. An overview of the company in the processing of metallurgical residues, as well as a review of the different technologies developed for the mining sector, is presented in this keynote conference.
