Beneficiation of Iron Ore and the treatment of magnetic iron taconites, stage grinding and wet magnetic separation is standard practice.This also applies to iron ores of the non-magnetic type which after a reducing roast are amenable to magnetic separation. All such plants are large tonnage operations treating up to 50,000 tons per …
Taconite (iron ore) pellets abrade during handling, forming large quantities of fine particulate matter that are easily carried by the air as dust. This dust must be controlled in order to meet air quality standards for particles finer than 10 µm (PM 10).It has been assumed that the most effective method for suppressing dust is to spray the pellets with …
separation of iron ore. 1 Edison's plans to separate low-grade iron ore were dashed by the competitive edge that rich, natural ore had in the marketplace, but the Wizard of Menlo Park proved that magnetic separation of low-grade iron ore was certainly feasible. "Pebble mills" are used in taconite processing operations to perform the
There are no known taconite deposits on the 225,000 acres of federal land where mining is now banned for 20 years. And only 2 parcels contain a small amount of native iron ore.

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 approximately 60 percent iron and about ½ inch in diameter. These pellets are then utilized, mainly, in blast furnaces making iron and steel and in the cement industry. Rule History
