The crushed ore is then transported to the mill site for crushing, grinding, classification and concentration. the second stage, grinding, is a wet operation which requires initial flotation and water to make a slurry. the hydrocyclone operates between each grinding operation to classify the type of particles: fine or coarse (long et al., 1998).
Physical Beneficiation An Overview | Sciencedirect Topics
The first step of physical beneficiation is crushing and grinding the iron ore to its liberation size, the maximum size where individual particles of gangue are separated from the iron minerals. a flow sheet of a typical iron ore crushing and grinding circuit is shown in figure 1.2.2 (based on ref. 4).this type of flow sheet is usually followed when the crude ore contains below 30 iron.
The stora sahavaara and hannukainen iron ore resources are located near the borders of sweden and finland. these deposits are categorized as iron oxide copper gold (iocg) type, which typically contain magnetite with varying amounts of sulphides which are commonly, though not always, associated with copper, gold and potentially other metals.
