Mining of copper produces dust and waste gases like sulfur dioxide, which contributes to air pollution. While miners minimize this pollution by trapping sulfur dioxide gas and using it to make sulfuric acid, the process of recycling copper rarely contributes to gas emissions that can pollute the environment.
mining of copper was analysedas well as the profits of traditionally mine copper versus the secondary production option. The environmental aspect was analysed by exploring the carbon dioxide emissions of both opposing processes. It was found that the recycling of copper leads to reduced carbon dioxide emissions than the traditional copper ...
