1. Introduction. The flotation processes performed in the main iron ore beneficiation plants located in the Iron Quadrangle region (Brazil) consist of flotation of natural fine particles (below 0.15 mm, without grinding) or flotation of all the material after grinding using ball mills (run of mine).

Gold grains are observed in a variety of forms, such as coarse-liberated native gold grains, and ultra-fine grains associated with sulfide or non-sulfide mineral particles, in the form of solid solution in sulfide minerals, mainly pyrite. In the flotation of gold ores, bulk sulfide mineral flotation is generally applied to maximize gold recovery. …

control of a flotation process are classified as follows: The tendency of the ore to have variable physical, metallurgical, and surface properties produces significant changes in a flotation circuit. The particle size range of the flotation feed can be substantial because of ore hardness changes and changes in the operation of the grinding circuit.

Gold flotation process is suitable for processing gold bearing sulfide ore with fine particle size and good floatability. During flotation, sulfide ore is enriched into sulfide concentrate as a carrier for gold. Flotation can also be used to process polymetallic gold-bearing sulfide ores and carbonaceous ores. Gold flotation machines:

The calcine has an acid reaction, and before it can be handled in contact with iron and steel, it must be neutralized. This is carried out in a preliming step in a 7- by 7-ft. turbo-agitator, which oxidizes the ferrous salts and precipitates the corrosive sulphates and chlorides present as hydrates.

The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.

At the Wiluna mine, the gold ore was floated at a slightly elevated pH of 8.2 using copper sulfate, PAX, and Interfroth 50. A unit flotation cell was included in the milling circuit at the Beaconsfield mine. Copper sulfate was added to the mill, while SIBX was distributed to three different locations in the flotation circuit.
