· Keywords: Flotation; Iron Ore; Slimes . 1. Introduction . The concentration of iron ore by flotation is a technique consolidated worldwide for mineral particles ranging from 10 to 250 μm [1]. In Brazil, all the main pellet-feed producers use re- verse flotation, being the tailing made up mostly of quartz
· The mineral composition of copper–cobalt ores is more complex than that of copper sulfides, and it is also difficult to discard tailing efficiently in primary flotation for the fine-grained disseminated of ore. In this work, a mineral liberation analyzer (MLA) was employed to study the characteristics of minerals. As a significant mineralogical characteristic, the liberation degree …
· Flotation behavior of copper and nickel from mine tailing was investigated un-der varying concentrations of PAX ranging from 0 g/t to 200 g/t when other flo-tation parameters were fixed at 200 g/t of MIBC concentration, 50 g/t of pulp density, slurry pH of 5400 rpm of stirring speed and 6 minutes flotation time. As
· Tedi tailing dam failure is a human consequence of the discharge of about 2 billion tons of untreated polluted mining waste/slurry into the River system ranking it one of the worst human environmental disaster. (Source: ... Flotation tailings account for ∼98% of the ore fed to the concentrator. ... Diamonds. Reports about ...
Research conducted for Sulphur removal from iron ore tailing found that froth flotation can be combined with ... of kimberlite tailings obtained from diamond source rock …
· Highlights Flotation for beneficiation of a tailing fine coal slurry sample. MIBC and kerosene as frother and collector. Flotation yield and combustible recovery depend on frother concentration. Best operation condition was 30 ppm frother MIBC and 2.0 lb/t collector kerosene. Ash of floats increased consistently with flotation time.
· A novel flotation process with no dispersant and depressant as well as no desliming was developed. It showed that this process was effective in recovering the tin values from the tailing slime assaying 0.18% Sn, and produced a concentrate assaying 3.5% Sn with the recovery of …
· The five basic types of reagent used in froth flotation recovery include collectors, frothers, depressants, activators and modifiers. When designing the processing plant, the types and quantities of reagents used should be …
Rougher flotation Regrind of the rougher concentrate to ~15-20 µm (P80) Cyanide leaching of the reground flotation concentrate Cyanide leaching of the flotation tailing No refractory association of gold with arsenic sulphide was detected; The samples tested did not exhibit any preg-robbing or other refractory characteristics;
· Diamond mining equipment normally in the process like first use vibration feeder to feeding material to trommel scrubber, After trommel scrubber for washing clean, and separator big size out, then to vibration screen. Vibration screen also for separator different sizes. The equipment includes trommel scrubber, vibrating screen, jig concentrator, slurry pump, …
As a result of these flotation tests carried out with different flotation conditions, a flowsheet for the treatment of this tailings can be proposed as shown in Figure 3 Tailing
· Mine tailings are the finely ground residue from ore extraction. The grain size of the tailings depends on the nature of the ore and the milling process. Size measurements (Robertson, 1994) of tailings from four mines in Ontario, Canada, indicated the tailings materials to be predominantly silt and fine to medium sand with <10% clay content.

· Diamond drilled core has been a HQ size and recoveries are consistently across all drill holes intercept reported. ... Flotation Tailing Rougher Flotation Target P 80 = ~100 µm Grind Tailing to Filtration & Discharge Flot Conc CIL Leached Flotation Concentrate Combined Flotation Tail+Conc CIL
Flotation tailings. The operator of a waste water treatment plant was looking for a pump with dry-run capability for his flotation system. In the flotation system, substances on the surface of the flotation tank are suctioned off using a rotating suction arm. Previously an eccentric screw pump had been used for this purpose.
