The Humboldt Mill is a historic brownfield site built by Cleveland Cliffs Iron Company in the 1950's for milling of iron ore from their adjacent open pit mine. Cleveland Cliffs ceased operations in the early 1980's and the pit began to naturally fill with water. The property was sold to Callahan Mining Company who began milling gold from ...

• Carbothermic reduction of iron ore (Hametite) in blast furnace is a well known process. Overall process is written as: • Ironore oxide mineral + gangue + Reducer (C) + flux + hot blast oxygen enriched air = Pig iron (liquid) + Slag (liquid) + waste gas (CO,CO2,N2) • Iron ore contains Fe2O3, along with gangue materials such as SiO2, Al2O3.

The iron ore extracted in the deposits, mostly by blasting, is initially very coarse and unwieldy, which gives this untreated rock the name coarse ore. After the coarse ore has been extracted, it is crushed directly at the deposits with the aid of cone crushers or jaw crushers to more manageable sizes of approx. 15 mm.

Processing. Sino Iron's Processing Plant is where we transform the magnetite ore into high-quality, premium magnetite concentrate. This is the heart of our operation at Sino Iron. Before the ore arrives at the Processing Plant by conveyor, it's already been reduced down at the in-pit crushers to roughly the size of a house brick.

The choice of grinding circuit is based on the density and hardness of the ore to be ground. Although use of the rod or ball mill grinding is quite common, a few facilities use autogenous or semi autogenous grinding systems. Autogenous grinding uses coarse pieces of the ore itself as the grinding media in the grinding mill.
