    Descriptions of the use of a flotation process have been found in ancient Greek and Persian literature suggesting its antiquity. During the late 19th century, the process basics were discovered through a slow evolutionary phase. During the first decade of the 20th century, a more rapid investigation of oils, froths, and agitation led to proven work place applications, especially at Broken Hill, Australia, that brought the technological innovation known as froth flotation.

    Queiroz 2003 verified that, for certain itabirite ore types, the use of attrition allows the increase of the mass recovery to the slimes and flotation concentrate fractions and the decrease of iron grade in the flotation tailings, iron grade in the slimes and SiO 2, Al 2 O 3 and P grades in the concentrate, resulting in higher figures for Gaudins selectivity index.

    Column Flotation SGS

    Today column flotation hase . an accepted means of froth flotation for a fairly broad range of applications, in particular the cleaning of sulfides copper, zinc, lead and molybdenite and the flotation of iron ore, phosphate and coal. Flotation columns differ dramatically from mechanical flotation machines in . several ways:

    Treatment and Recycling of the Process Water in Iron Ore

    Since the chemistry property of process water is entirely different from fresh water, there is a concern about the possible effects of theponents on the efficiency of the flotation process . In iron ore flotation process, a large amount of NaOH is taken to adjust the pH.

    Iron Ore Flotation in the Presence of Polyacrylamides AusIMM

    Flotation is an important process used in the concentration of iron ores. One of the challenges for process engineers is the low metallurgical recovery associated mainly with the fines fraction. In this work, the use of synthetic flocculants in iron ore reverse cationic flotation was investigated. The flocculants utilised were polyacrylamides of high molecular weight

    The micro flotation and Bench scale flotation results further verify that TTPC presents a stronger collecting power and much better selectivity for iron ore reverse flotationparison to the conventional collector DTAC. Furthermore, the corresponding adsorption mechanism of TTPC on the quartz have also been investigated in detail.
