Metal ore mining and its processing including copper, lead-zinc, gold, iron, etc., create adverse environmental effects. Mining ore mining involves the removal of large quantities of rock from the ground. Ore deposits in shallow depths are mined by surface mining methods. Surface mines produce large quantities of waste rock than underground mines.

Energy and environmental problems are closely related, since it is nearly impossible to produce, transport, or consume energy without significant environmental impact. The environmental problems directly related to energy production and consumption include air pollution, climate change, water pollution, thermal pollution, and solid waste disposal.

The potential environmental impact of historical mining and ore processing on stream sediments and water was studied in a small siderite iron ore deposit with diverse sulfide mineral paragenesis. The main aim was to characterize solid carriers of potentially toxic elements (PTEs) in stream sediments and mine waste, to understand their fate in fluvial systems.
