11.23 Taconite Ore Processing

The taconite ore processing industry produces usable concentrations of iron-bearing material by removing nonferrous rock (gangue) from low-grade ore. The six-digit Source Classification Code (SCC) for taconite ore processing is 3-03-023. Table 11.23-1 lists the SCCs for taconite ore processing. Taconite is a hard, banded, low-grade ore, and is
