2 environmental impacts. Upgrading the furnace charge can improve process efficiency and decrease electricity consumption. An oxide manganese ore, consisting mainly of pyrolusite, calcite and goethite, was thermally upgraded by calcination and solid-state reduction. During calcination of the ore at 900-1100°C, carbonates and hydroxides were decomposed and a considerable …

619· This furnace has little, if any, air infiltration and undercover combustion. Water leaks from the cover into the furnace must be minimized as this leads to excessive gas production and unstable furnace operation. Products prone to highly variable releases of process gases are typically not made in close top furnaces for safety reasons.

Currently, manganese furnace dust is accumulated in large ‘settling ponds’. Major factors preventing recycling of the manganese furnace dust to the ferroalloy furnace are handling, due to its high water and organics contents, and the long term accumulation of zinc in the furnaces, which can cause irregularities in their operation.
