Smelting is a high-temperature process that requires a furnace capable of reaching temperatures of:
500-700°C
1000-1200°C
1500-1700°C
2000-2200°C
Smelting is a high-temperature process used to extract metals from their ores. It involves heating the ore in a furnace to a specific temperature range where the desired metal can be separated from the impurities.
The temperature required for smelting depends on the specific metal and ore being processed. However, in general, smelting processes typically require temperatures in the range of
At these high temperatures, the ore melts, and the desired metal separates from the impurities to form a molten metal known as the "matte." The impurities, often in the form of slag, float to the top and are removed.
The specific temperature range of provides sufficient heat to melt the ore and allow the desired metal to be separated effectively.
Therefore, option (3) is the correct choice for the temperature range required in the smelting process.
