Detailed Solution

The above statement is true.
The process of obtaining a metal as an element or a simple compound from its ores by heating above its melting point in the presence of oxidants such as air and coke is called fusion. Copper was the first metal to be melted, followed by tin, lead, and silver. A forced furnace is used to achieve the high temperature required for smelting. In modern copper smelting, an echo furnace is used. In this process, impurities are removed by adding a suitable flux. It reduces oxide ore to molten metal. An example is the reduction of iron ore (iron oxide) by coke in a blast furnace to produce cast iron.
