In the previous, coal itself was used to warmth and separate the ore. However, coal releases impurities similar to sulfur when it’s heated, which may make the resulting steel weak. The quick environmental impact of underground mining seems much less dramatic than floor mining. There is little overburden, but underground mining operations go away important tailings.
