Abstract

In the present research, the energetic and environmental analysis of the lateritic ore drying process in a horizontal rotary kiln it carried out. It aims to assess the feasibility of the use of gases products of the ore reduction process in vertical furnaces. In addition, it is analyzed the energetic and environmental impact of the use of these gases as energy sources. In order to meet the objectives outlined, measurements were taken at the facility, obtaining the main operating parameters. It was also applied the balance and energy methods to verify that the use of the waste gases brings to the process the 18 % of the energy required and reduces in a 26 % the fuel consumption.
