Electrostatic separation is one of the most misunderstood physical processes used to beneficiate minerals. Nonetheless, millions of tons of titanium ores, iron ores and other minerals are processed every year economically, efficiently and safely. Over the past ten years major advances in electrostatic separation and its application have occurred.
The process of separating a metal from its ore is known as smelting. Smelting is widely practiced today and has a long history dating back to the Bronze Age, when ancient peoples first learned the technique. Smelting methods range from the basic to the high-tech, and
Apart from the use of chemical methods as a way to recover precious metals, mechanical methods can be used which have proven to emit little to no pollution (2). Mechanical processes, such as shape separation, density-based separation, and electrostatic separation are widely utilized in the recycling
Electrostatic separation is frequently applied as a step in metal recycling operations, for metal recovery from electronic scrap and in the recovery of precious metals from used catalysts. Some examples will be described in Chapters 7 and 9 Chapter 7 Chapter 9 .
Aug 28, 2015 For recovering precious metals from waste printed circuit boards (PCBs), a novel hybrid technology including physical and biological methods was developed. It consisted of crushing, corona-electrostatic separation, and bioleaching. Bioleaching process is the focus of this paper. A novel bioreactor for bioleaching was designed.
Most separation techniques for waste electrical and electronic equipment (WEEE) require preliminary scrap-granulating operations to carry out mechanical component dissociation. Electrostatic separation is the selective sorting of electrically charged or electrically polarized granular WEEE under the action of the electric field forces.
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
Electrostatic separation is an effective and environmentally friendly method for recycling comminuted waste printed circuit boards (PCB). As a classical separator, the roll-type corona-electrostatic separator (RTS) has some advantages in this field. However, there are still some notable problems, such as the middling products and their further treatment, impurity of nonconductive products
Electrostatic separation is highly successful in certain operations, particularly in rutile recovery, however it’s suitability is limited due to the strict conditions of ore feed presentation to the separators. ALS currently operates several different separators, including CARPO, HTR,
Then, an integrated, definite, and systematic recovery route of full renewable metals from waste printed circuit board was proposed. The recovery route included temperature-control crushing, magnetic separation, high voltage electrostatic separation, vacuum gasification and

Separates resins and laminated metals; Electrostatic separators are for separation of metals and non-metals that cannot be separated by conventional magnetic separators such as: eddy-current separators, wind separators, or heavy-fluid separators. This unit is designed for separation of fine grain materials ranging from 0.1mm to 5 mm.
Gravity separation is one of the oldest technique in mineral processing but has seen a decline in its use since the introduction of methods like flotation, classification, magnetic separation and leaching. Gravity separation dates back to at least 3000 BC when Egyptians used the technique for separation of gold.
Characteristics of PCB / electronic component dismantling machine: The equipment adopts a new process of advanced mechanical crushing and high voltage electrostatic separation. Separating of metals and nonmetals after comminution and dissociation, the purity is high.

Electronic waste, or e-waste, is an emerging problem with developed nations as with developing nations. In the absence of proper collection and disposal systems, awareness, and proper regulations, the problem is rather more acute in developing nations. These wastes are environmentally hazardous on one hand and valuable on the other. They contain substantial amount of metal value, including
