Staged Flotation: Higher Recovery, Lower Footprint. Another concept that Eriez and others like Woodgrove are working on is staged flotation. Again, the technology is not new — Eriez has been running it's StackCell in coal applications for 15 years — but the company has recently redesigned it to handle base metals.
The current study investigated the effects of thiol collectors on the flotation of base metals (BMs) and platinum group metals (PGMs) ores. The properties of a single-mineral flotation test were conducted using sodium isobutyl xanthate (SIBX), sodium ethyl xanthate (), potassium ethyl xanthate (PEX), and sodium isopropyl xanthate (SIPX) …

With that, in flotation alone, water consumption reaches an average of 0.96 m 3 per ton [5], [6], [7]. However, despite great criticism, the flotation stage is how fine-grained ores (between 10 µm and 150 µm in hematite/quartz flotation) with low purity are concentrated [8]. Due to the depletion of natural mines and the reprocessing of ...
graded by froth-flotation process while high-grade ores can be utilized directly for metal recovery due to decrease in gangue content. The beneficiation process of sulfide ores includes size reduction-size classification, physical beneficiation processes and/or flotation steps. Anderson (2012) described a typical Chinese stibnite
Sulfide minerals are naturally more hydrophobic than most of the mineral groups and respond well to flotation. Even though, most sulfide ores contain minerals (e.g., chalcopyrite, pyrite, galena ...

For the flotation circuit of iron oxide, a uniform test design was conducted to estimate the optimum flotation reagent systems at different flotation temperatures from 20 °C up to 45 °C. The detailed uniform design optimization methodology was given in previous work 1. Uniform test design is a computer simulation accomplished in many ...
Rare earth elements are widely used in different industries such as chemical, metallurgical, and advanced materials, etc. (Murthy and Mukherjee 2001).Rare earth metals are added to different alloys to impart high-tech properties, strength, malleability, resistance to corrosion, etc. (Abaka-Wood et al. 2016). As many as 250 rare …

Abstract. The effect of ing agents of different chemical nature (amyl alcohol, glycolic ether, pine oil) on the flotation of halite from polyhalite ores using alkylmorpholine as a collector ...
1. Introduction. Mineral processing, particularly flotation, is a high-water-consumption industry. Mining water consumption in the United States accounts for 2% of the total social water consumption [1], whereas in Chile's Antofagasta region, which is highly dependent on mining, this figure is close to 70% [2].The large consumption of fresh water …
The aim of the study was to investigate the effect of different grinding conditions on the flotation response of Pt- and Pd-minerals from the sample ores. The most cathodic grinding environment was achieved using a CO 2 atmosphere with mild steel media during grinding or when using the N 2 atmosphere with nitric acid to adjust the pH …
Kumar and Mandre (2016) evaluated the selective flocculation to treat iron ores slimes applying polyacrylamine and guar gum as a flocculant and sodium hexametaphosphate as a dispersant. The results indicated that selective flocculation enhanced the Fe grade from 58.2% to 64.6% and an Fe recovery of 66.3% using …

The flotation recoveries of the fine and intermediate size pyrochlore at pH 7 under different concentrations of collectors are shown in Fig. 2.For the pyrochlore of intermediate size (median size = 64 µm), the recoveries increased with the increase of the collector concentration for all the four collectors, and the collecting ability followed the …
Phosphate ores enrichment by flotation have frequently been depicted as a bulk and unselective removal of gangue minerals (Sis and Chander, 2003). With the recovery of high grade phosphate concentrates as the sole aim, huge volumes of flotation tailings are constantly accumulating at the perimeters of concentrator plants (Taha et al., …
