How is sulfur mined and refined
WebClean metallic lead can be melted and refined directly, but compounds and lead alloys require smelting, using processes similar to those used with lead ores. Two-stage process In the two-stage process for secondary production, smaller rotary or reverberatory furnaces (Figure 3) are used rather than larger blast furnaces as this gives better control of the … WebThe higher cost of coal from underground mines reflects the more difficult mining conditions and the need for more miners. When coal is burned, it releases impurities that can combine with oxygen to form sulfur dioxide (SO 2 ). When SO 2 combines with moisture in the atmosphere, it produces acid rain that can harm forests and lakes.
