1. A region in a blast furnace or similar industrial process where oxygen is removed from ore or other materials, typically through the action of reducing agents such as carbon monoxide or hydrogen
The reducing zone in the blast furnace converts iron oxide into molten iron.
A zona redutora no alto-forno converte o óxido de ferro em ferro fundido.
2. In environmental science, an area of sediment or soil where oxygen is depleted, promoting reduction reactions and anaerobic conditions
The reducing zone beneath the water table prevents oxidation of certain minerals.
A zona redutora sob o nível freático previne a oxidação de certos minerais.
