Table 3 shows the specific surface area of the three size fractions. Tables 4 and 5 show the results of iron recovery in concentrate, SiO 2 content in concentrate and iron content in tailings for the three particle size fractions obtained for the different dosages of etheramine and corn starch and pH values.
With decreasing or increasing the upper size of the iron ore fines the mean size of the iron ore fines will change. With decreasing the coarser size fraction increases the finer size fraction in iron ore fines. 2.2. Sintering For each individual iron ore fines of different mean sizes, pot grate sinter experiments were carried out by preparing
encapsulation in iron oxides occurred more easily in the relatively ne size fraction of calcine 13,33, but the causes for this phenomenon are still unclear. Little research has concentrated on exposing the encapsulated gold in different size fractions of the calcine.
-12500 m fraction was separated at SGs ranging from 3.20 to 2.65. The gold was associated with arsenopyrite, and there was an almost perfect correlation between the gold and arsenic recoveries. The recovery is calculated based on sum of the fines fraction and sinks fraction from each separation stage.
