Abstract
The search for new technology to reuse the mining waste is in gran demand, for which reason this investigation evaluates the possibility to manufacture of ecological bricks made from mining residues. Bricks are one of the main materials used in construction and are generally made of clay, which is intensively extracted from soils, causing strong negative environmental impacts. Besides this, the firing process during the brick production releases high amounts of greenhouse gases into the atmosphere, because in Latin America generally wood or fossil fuels are used to reach the required temperatures in the furnaces. Ecuador is considered to be a country with high mining potential especially in gold, silver and copper. Therefore, one of the main objectives of the national government is the reduction of the environmental and social impact due to mining activities, promoting the technological development and modernization in the mining sector. However, to date the mining industry still produces significant amounts of residues, mostly in the form of solid waste, which generally damage into the environment. To avoid and mitigate this type of environmental contamination, this investigation use gold mine waste, resulting from the gravimetric concentration process, to produce ecological bricks.
