electrical separation in mineral processing


Concentration - Mineral Processing

The larger the ε the better the conductivity of the mineral and vice versa. In general those with ε>10 12 or more belong to conductors which can be separated by the usual high-voltage electrical separation while those below this value are difficult to sort by conventional electrical separation methods.

Electrostatic Separation - Leaders in Mineral Processing

For separating dry free flowing materials with particle sizes between 40-800 microns that exhibit electrical conductivity differences the Carrara range provides high efficiency separation to maximize process performance and minimize plant size.

Electrostatic Separation Procedure

Separation of minerals utilizing differences in their electrical properties may be carried out using an electrostatic separator. It will separate electrical conductors minerals such as cassiterite and rutile from those that are electrical non-conductors minerals such as zircon and siderite . The principle of separation is that as the particles to be treated are passed through an intense

Separation in mineral processing - MINERALLURGy

Separation in mineral processing is based on the physical and chemical properties of minerals and their relationship to the appli ion of concentration technologies. The proprieties differences between minerals are listed below: 1. Density. 2. Magnetic susceptibility. 3. Electrical conductivity. 4. Superficial proprieties. 5. Solubility. 6

Electrical Separation of Minerals

For characterising the electrical behaviour of chemically conditioned mineral samples and after charging the minerals with the body of the stainless steel mill they are subjected to an electrostatic free fall separator by using a steel feeder. Based on the polarity and the magnitude of the charges acquired by mineral grains they are attracted by the positive and negative electrodes and

Electrical Separation - an overview ScienceDirect Topics

Earlier in this chapter the possibility of combined magnetic and electrical separation was noted particularly in the processing of heavy mineral sand deposits. Table 13.3 shows some of the common minerals present in such alluvial deposits along with their properties related to magnetic and electrical separation.

Heavy Minerals Processing Plant Design Machine and Install

Electric separation: Sometimes heavy minerals are not easy to be separated by common processing technologies then electrical separation may be another choice. It takes advantages of the electrical conductivity differences of different heavy minerals for example rutile can be easily recovered by electric separation.
