Taconite Iron Ore Processing National Emission Standards

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

Removal of Silica and Alumina as Impurities from Low-Grade

This study investigates the removal of silica and alumina as impurities from hematite based low-grade iron ore containing 34.18 mass iron 31.10 mass of silica and 7.65 mass alumina. Wet high-intensity magnetic separation (WHIMS) and reverse flotation (RF) were investigated. In WHIMS process 93.08 of iron was recovered with a grade of 53.22 mass at an optimum magnetic density of
