Jan 01, 2012 · Oxalic acid effectively activates pyrite flotation and can thus be applied as the activator of lime depressed pyrite. (2) The main activation mechanism pyrite with oxalic acid is that, oxalic acid is adsorbed on the surface of pyrite and reacts with the hydrophilic insoluble remainders, such as CaCO 3 , Ca(OH) 2 and Fe(OH) 3 , desorbing from the pyrite surface as a form of soluble complex

Froth flotation is one of the most popular operational processes for mineral beneficiation. In ore/mineral beneficiation, froth flotation is a method by which commercially important minerals are separated from impurities and other minerals by collecting them on the surface of a froth layer. Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out

Activator: Promote the action of minerals and collectors or remove the inhibiting effect. Copper sulfate, silver nitrate and lead nitrate can be used as activators when the collector is the xanthate; ... Collector: Add it to the agitation tank or flotation cell with the foaming agent, while the insoluble collector (such as cresol aerofloat

In general, the flotation of minerals containing titanium needs to be activated by metal ions due to a lack of activating sites on their surface. However, the activating process is indirectly inferred due to the lack of direct experimental observation. In this study, atomic force microscopy (AFM) was used to observe the activation process. The results revealed that the hydroxyl compounds of

The adjustment agent includes activators and inhibitors, and it can change the characteristic of the material surface and influence the interact of material and collecting agent.The order: for ore flotation the sequence should be: PH adjusting agent, inhibitors or activators, foaming agent, the collecting agent; and for the inhibited mineral the sequence is: the activator, collecting agent and foaming agent.The …

In the ZnS flotation, the maximum separation achievable for ZnS using froth flotation has been shown to be a grade of 72.57% and a recovery of 95.43%. At this time, FeAsS removal of 87.8% (0.16% As) could be successfully accomplished under pH 11, and 800g/t Zn activator (CuSO4), 75g/t frother (AF65), 60g/t collector (AP211) and 600g/t As depressant (NaHSO3)

Dec 09, 2019 · The KYF-680 Machine, a new generation forced-air flotation cell, has been developed by BGRIMM, China, in recent years and the capacity of 680m3 makes it the largest cell in the world at present. The first unit has been installed, tested and is currently operating at the DeXing Copper Mine in China to reprocess the tailing

During flotation of the fine stream, acid and/or activator may be added at the conditioning, cleaning, re-cleaning, cleaner-scavenging or third cleaning stage. During flotation of the coarse

A new depressant for use in enhanced separation of polymetallic sulphides is described. The depressant agent is used in conjunction with conventional collector agents and frothing agents in the flotation separation of copper, nickel, lead, zinc sulphides by depressing iron sulphides such as pyrrhotite, pyrite and marcasite in the tailing

Upon flotation treatment in a system of pH not greater than about 7 in the presence of a xanthate collector (a known class of collectors 0 suitable for use with sulfide minerals) and a depressant for the cobaltite (of which many wellknown examples are available as hereinafter described), the cobaltite is still substantially nonfloatable but the pyrite and pyrrhotite are flotable, 5 especially in the presence of an …

Froth flotation process is one of the most widely mineral processing method used in the production. It uses the difference of physical and chemical properties in mineral surface, and rely on air bubbles buoyancy in the pulp to realize mineral separation process. On the basis of the flotation separation, Xinhai has developed a series of flotation reagents, which not only reduce 10% reagent consumption, but also increase 20% flotation …

Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to

Single mineral flotation tests were carried out by using XFG type laboratory flotation machine with a 40 ml flotation cell, and the impeller speed was fixed at 1900 rpm. The mineral suspension (either chlorite or hematite) was prepared by adding 3.0 g of minerals to 40 ml of distilled water

In U.S. Pat. No. 3,979,282 it is recognized that ferrous iron is capable of acting as an activator when added as a water soluble salt in a clay conditioning and flotation procedure. There is no disclosure or suggestion, however, in this patent or in any other prior art of taking steps to prevent the oxidation of the added ferrous salt before or during the conditioning operation to the ferric condition

Hydroxamate FlotationThe above-mentioned flotation processes are based on the use of the fatty acid or tall oil type of collectors, which require the use of divalent or trivalent activator cations. The presence of activator ions makes the process sometimes difficult to control because of the necessity to maintain a proper balance between the amounts of collector and activator added
