MEI Blog: Flotation '17 Conference Diary

After wet milling, the ores yielded different concentrations of Cu and Fe in the pulp and also significantly different recoveries. Dry grinding also affected the behaviour of the ores differently. Flotation recovery is a function of the size distribution and associated mineral liberation produced from comminution, which is affected by classification.

Iron Ore

Dry primary and secondary crushing and screening is followed by wet processing by HPGR and ball mill grinding followed by reverse flotation to remove silica and Vertimill regrinding. The regrind circuit reduces the particle size distribution to P80 passing 36 µm (microns) to prepare the feed for the slurry pipeline.

Oxide and Reverse Flotation | Mining | SGS

In reverse flotation, proper reagents induce the pay minerals to become hydrophobic (water repelling) and the waste minerals to become hydrophilic (water attracting). Aeration is added through spargers at the bottom of the flotation cell.

Pyrite Reverse Flotation

Its reverse flotation of magnetite where pyrite is floated. Though the pyrite concentration looks to be lower (with S<0.5% in feed) it may be worth looking at the pyrite floats around the Kalgoorlie area in Western Australia as these systems are generally highly saline (off the top of my head KCGM Fimiston and Kanowna Belle) and do employ

grinding as a function of time in batch grinding or steady state mill discharge in continuous mills (Herbst et al., 1968). In order to evaluate the kinetic behavior of an itabiritic iron ore in the grinding process, simulation studies were performed with the results of laboratory tests. This study allowed

that deposits the feed just above the grinding media), or bottom fed. In the case of Minas Rio, the cyclone underflow is fed by gravity into the bottom of the Vertimills. The feed is therefore first forced through the grinding zone (thereby minimizing the potential for bypass), before it reaches the classification zone.

Kinetics of flotation. Order of process, rate constant

Current flotation systems applied in the reverse flotation of quartz (SiO2) from hematite in the iron ore industry have difficulty in collecting quartz particles larger than 150 µm and

Evaluation of grinding circuits for iron ore

Each line has an independent grinding circuit, with two ball mills and three hydrocyclones batteries. The product from the grinding circuit feeds a desliming circuit, which produces an underflow that is directed to the flotation circuit feed, and an overflow which forms part of the final tailings. Figure 1 illustrates the plant flowsheet.

Reagents in iron ores flotation

Despite the existence of records of the use of specific frothers (alcohol and polypropylene glycol) in the reverse flotation of iron ores in the USA (Houot, 1983), their use is not a common plant practice. Flotation is being performed in a pH range that stabilises both, the cationic and the molecular species of the amine, rendering possible that the cationic species act as collector and the molecular species act as frother.

WO2014055502A1

[0045] In exemplary embodiments, the flotation process is a reverse or inverted flotation process, for example a reverse cationic flotation process. In such processes, the flotation of the desired mineral is selectively depressed when compared to the flotation of the gangue so as to facilitate separation and recovery of the desired mineral.

Reverse flotation separation of hematite from quartz assisted

During the reverse anionic flotation of iron ores, quartz is activated by the calcium chloride under strong alkaline condition, and iron ores are generally depressed with starch due to the selective adsorption of starch on the surface of iron ores as reported earlier (Ravishankar and Khosla, 1995, Weisseborn et al., 1995, Filippov et al., 2010).
