Microorganisms were naturally present in the wastes; neither special inoculation nor preliminary treatment was applied. Ore tailings processed after flotation of copper ores contained about 312 mg kg −1 of titanium. Ore residues were ground and sieved, the 250–750 μm fraction was removed and selected for experiments.

In the tests, the effects of particle size, pH, collector types and their amount were tested. The results showed that efficient separation of titanium bearing minerals could be achieved by oleate flotation at around pH 5, after grinding the ore down to -180μm. Oleate provided results superior to sulphonates and succinamate.

1. Introduction. Pyrochlore (Na,Ca) 2 Nb 2 O 6 (OH,F) is the most economically important niobium-bearing mineral and is typically upgraded by flotation using an amine-based collector. The pulp pH is maintained between 5.5 and 7 in the rougher circuit and is gradually dropped to as low as pH 2 in the final cleaner stage (Gibson et al., …

Generally on complex titanium ores it is advisable to use the combination flowsheet shown. An ore of magnetite and ilmenite may, however, employ wet magnetic separation to remove magnetite, and all flotation for recovery of the ilmenite in a high grade product. In this case all the gravity … See more

Vanadium-containing titanium magnetite is the main source of V and Ti in the internal market. About 75% Fe, 82% V, and 44% Ti pass into iron concentrate during ore enrichment [].Therefore, the question of how to improve comprehensive utilization of vanadium-titanium magnetite concentrate (VTMC) is of decisive importance for the …

A total of 70 titanium minerals are known, as mixtures with other minerals and also impurities. Only a few of these minerals are of any economic importance. This chapter …

Flotation of pyrochlore was more selective over ilmenite when SHMP was added before BHA, similar to a cleaner flotation stage in real-ore flotation. Contrary to micro-flotation results titanium recovery was high (more than 60% TiO 2 recovery in most cases) under similar pulp conditions in bench scale flotation, an indication that to some …

Processing titanium ore includes several stages for extracting titanium and turning it into a final product. Our company has developed 2 main concepts for dressing titanium ores, the main feature of which is the method of obtaining ilmenite concentrate: 1. Scheme of magnetic, flotation, and electrostatic separation: 2.

While demand for metals like copper, cobalt, lithium and iron ore is projected to reach record highs by 2050, ore grades are decreasing, orebodies are becoming more complex, and fewer tier 1 deposits are …

The main equipment used are spiral chute, shaking table, jig and so on. The reselection is often combined with the silver ore flotation process. Cyanide leaching methods is mainly used for silver sulfide minerals. In order to increase efficiency, gold and silver concentrates are selected and then cyanided on-site to produce gold and silver.

As proper grinding fineness is crucial to the flotation results, the particle size of titanium ore generally needs to be ground to less than 0.074 mm for a better …

The flotation results with oleic acid and dodecylamine show better recovery of iron values in the hematite–quartz mixture as well as in the naturally occurring high silica ore compared to the hematite–clay mixture and the high alumina ore respectively. Similarly results on a variety of iron ores show that high silica content as quartz in ...

Titanium (Ti): Titanium is the main element in titanium ore and is typically present as titanium dioxide (TiO2) in various mineral forms, such as ilmenite, rutile, and leucoxene. The titanium content in titanium …

The reminder of the flotation testwork was the same as that with the low titanium ore. The flotation conditions and procedure followed are summarized in Table 3 and Figure 2 respectively.
