Tribo-electrostatic separation is the chosen method to address our work, which has been applied successfully in industrial mineral processing [1], but it is constrained to very few materials, like potash ore and coal.
In analogy with froth flotation using chemical agents to enlarge the difference of hydrophobicity, this study was undertaken to examine the feasibility of enlarging the differences in surface work function of coal components to improve the electrostatic separation. Two coal specimens from Alberta having medium ash and low sulfur …

The Unterbreizbach (Thuringia) and Wintershall (Hesse) sites of the Werra integrated production plant will be converted to a dry processing method by 2026/2027. K+S is relying on the so-called …
ST Equipment & Technology (STET) develops and manufactures Triboelectrostatic Separators that provide a high rate and completely dry beneficiation for pulverized coal fly ash. The STET separation process has been used commercially since 1995 for pulverized coal (PC) fly ash beneficiation and has generated over 20 million tons of high-quality ...
The STET dry electrostatic fine iron ore separation process offers many advantages over traditional wet processing methods, such as magnetics or flotation, including: No water consumption. The elimination of water also eliminates pumping, thickening, and drying, as well as any costs and risks associated with water treatment and disposal.
The expanding role of electrostatics as applied to minerals and related fields is covered. New and existing forms of electrostatic separation are classified into two broad groups: …
Electrostatic separation, as the name suggests, works on the principle of charge differences. When subjected to an electric field, particles with different properties acquire charges at varying levels. Following this, the charged particles experience an electrostatic force in the electric field. The disparity in the obtained forces results in a ...

Two main process routines can be distinguished depending on differences in raw material properties: separation of conductors from non-conductorsseparation of …
One of the key features of electrostatic separation is the charging of particles. In order to separate particles, they must first be electrically charged. Charging particles can occur in a number of ways, but the STET separator uses triboelectric charging. In order to do this, minerals are fed into the separator and fall into an electrode gap ...
The electrostatic separation technique is generally utilized for recycling metallic materials from electronic waste [1,2,3,4,5,6].This dry separation technology is also successfully employed in mineral processing [7,8,9,10] and the food industry [11, 12].As a perfectly dry method, electrostatic separation is an environmentally friendly technique …
Crude potash salt is conditioned for separation into its components by means of an electrostatic field by grinding the salt to disintegration and contacting the ground salt with a conditioning agent, such as salicylic acid, which has been converted to the gaseous state, such that the conditioning agent draws up onto the surfaces of the salt crystals by …
