The following are the stationary sources of air pollution for the mineral processing industries, and their corresponding air pollution regulations and guidelines. To learn more about the regulations and guidelines for each industry, just click on the links below. National Emission Standards for Hazardous Air Pollutants – NESHAP.
The iron ore processing industry produces usable concentrations of iron-bearing material by removing nonferrous rock (gangue) from low-grade ore. In the United States, predominant iron ore is taconite which is a hard, banded, low-grade ore. Ninety-nine percent of the crude iron ore produced in the United States is taconite.
• EPA issued the air toxics standards for Taconite Iron Ore Processing on October 30, 2003. The rule applies to major source facilities engaged in separating and concentrating iron ore from taconite (a low-grade iron ore) to produce taconite pellets. These taconite pellets are then used as feed in blast furnaces to produce steel .
Taconite iron ore processing plants separate and concentrate iron ore from taconite, a low-grade iron ore containing 20- to 25-percent iron, and produce taconite pellets, which are 60- to 65-percent iron. Taconite iron ore processing includes crushing and handling of the crude ore, indurating, and finished pellet handling.
On May 15, 2023, the Environmental Protection Agency (EPA) issued a proposed rule titled, "National Emission Standards for Hazardous Air Pollutants: Taconite Iron Ore Processing Amendments." The EPA is extending the comment period on this proposed rule that currently closes on June 29, 2023, by 8 days.
They simply process ore bodies at the respective facilities that are lower in mercury that are unavailable to the other sources o No proven mercury control technology used in the industry o No basis for averaging penalty 14 USEPA Proposed Rule: Taconite NESHAP Review EPA has determined that the Taconite Iron Ore Processing NESHAP Source
Table 2-2 provides a key to the SCCs for taconite ore processing, as indicated in Figure 2-1. Liberation is the first step in processing crude taconite ore and consists mostly of crushing and grinding. The ore must be ground to a particle size sufficiently close to the grain size of the iron-bearing
The taconite pieces are scooped up by electric shovels. Each shovel can hold up to 85 tons of rock. The shovels place the taconite into giant dump trucks. These trucks are as big as a house and hold up to 240 tons of taconite. The trucks take the taconite directly to the processing plant, or the taconite is transported if further away. Crushing
Each taconite iron ore processing plant is located directly proximate to its own mining source. Transportation costs of procuring raw materials from other locations are prohibitive. A plant has no access to the raw ore used by another plant and, consequently, could not duplicate the mercury emissions performance of the other plant. ...
• EPA issued the initial air toxics standards for Taconite Iron Ore Processing on October 30, 2003. The rule applies to major source facilities engaged in separating and concentrating iron ore from taconite (a low-grade iron ore) to produce taconite pellets. These taconite pellets are then used as feed in blast furnaces to produce steel.
A taconite iron ore processing facility separates and concentrates iron ore from taconite, a low-grade iron ore, and produces taconite pellets, which are …
