2021-5-5  Among the factors affecting the flotation of pyrite, or any metallic sulfide mineral, are the following: Kind and physical condition of mineral; size of mineral grains; method of pulverizing the mineral; kind and physical condition of gangue associated with the mineral; kind of oil, oils or other reagents used as flotation agent; amount of oil, oils, or other reagents

Hydrophobic Agglomeration of Fine Pyrite Particles

Reagents have a significant effect on the interaction between mineral particles. However, there are few reports available on the hydrophobic agglomeration behavior of fine pyrite by common flotation reagents such as activator copper sulfate, collector butyl xanthate and frother terpineol.

The depression of pyrite in selective flotation by

Pyrite may float due to natural or self-induced hydrophobicity or collector-induced hydrophobicity. Its flotation can also be enhanced by the activation of copper or lead ions emanating from other minerals. Depressants are generally required to selectively depress pyrite.

Hydrophobic Agglomeration of Fine Pyrite Particles

Flotation reagents can effectively reduce the repulsive energy between pyrite particles and increase the attraction energy between particles, which is conducive to the hydrophobic agglomeration of fine pyrite.

5 Types Of Gold Flotation Reagent Mining-pedia

(2) Gold flotation reagent types. In gold flotation plant, the commonly used inhibitors are: lime and cyanide. Lime; Lime is an effective inhibitor of minerals such as pyrite and pyrrhotite, and can also be used as a pH regulator. Lime is easy to obtain and low in price. It is a commonly used inhibitor, and it is also an agglomeration agent for sludge.

equipment, which is available due to over capacity of the mill compared to the current rate of mining. To produce pyrite concentrate, Magma introduces the copper tailings sands into standard flotation cells, adding water, additional flotation reagents (the same reagents used in the copper flotation circuit) and sulfuric acid (See Figure 2).

2009-8-26  minor pyrite. The nature of the mineralization of these ores is such that the natural pH of the ore slurries is always alkaline, at a pH of around 9. The PGEs are recovered by flotation and the flotation of the BMS is treated as a bulk sulphide recovery. In order to maximize PGE recovery, the recovery of all the BMS needs to be optimized.

The practice of pyrite flotation in South Africa and

The flotation of pyrite is of great importance to the gold mining industry in South Africa and Australia. The flotation plants fall into a number of categories, viz. flotation after milling, flotation of current residues and reclaimed residues, flotation of refractory ores and the flotation of gold-copper ores.

Hydrophobic Agglomeration of Fine Pyrite Particles

Flotation reagents can change the surface properties of minerals, leading to differences in the interaction between mineral particles and affecting the mutual aggregation or dispersion of particles. In this work, we studied the role of activator copper sulfate, collector butyl xanthate and frother terpineol in adjusting the potential energy of pyrite particles from the perspective of the

Role of dixanthogen on pyrite flotation: solubility

The xanthate adsorption mechanism on pyrite was investigated with an emphasis on solubility studies. Additionally, adsorption studies, Eh and infrared spectrophotometer measurements were performed. Pyrite floats at pH levels between 3 and 6 using ethyl and amyl xanthafes with a maximum at pH 4. The solubility of pyrite in the absence and presence of xanthate was investigated in detail with

The flotation of sphalerite mine tailings as a

The collected data concern the origin of the material, the concentrations of useful species, the reagents used, the results obtained, and, in some cases, the determination of the optimal particle size (d 80) of the material with which the flotation is fed.The cases relating to the treatment of sulphide minerals have been further divided based on two specific analyses: the effects of the pH and

The Complete Collection of Copper Beneficiation

2021-4-30  In the flotation process of the copper mine, the use of flotation reagents to change the surface properties of the mineral is a flexible and effective way to control the flotation behavior. It is also an important reason why flotation can be widely used in mineral processing.
