Major Mines Projects Direct Shipping Ore (DSO) Mine

The run-of-mine ore processing consists of crushing and wet screening to reduce the ore to - 6 mm size. Gravity separation methods, employing jigs, spirals and hydro-classifiers, are utilized to upgrade coarse fractions. Materials below 0.1 mm are separated by wet high intensity magnetic separators (“WHIMS”).

Iron Mines in Michigan - NASA

But by the 1950s, most of the easily accessible ore with high concentrations of iron was gone, and mining companies had to dig much deeper and develop new techniques to extract and concentrate iron from lower-grade ore. Today, mine operators in Michigan’s Upper Peninsula are generally after taconite, a low-grade ore that was once considered ...
