A tribo-electrostatic separation was developed to produce protein concentrates from yellow pea flour. A mixed-level full factorial experiment followed by a multiple linear regression model was developed to assess the impacts of airflow rate, plate voltage, milling type, and screen size as operating factors on protein content, …

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 …

best process available for complex zinc ore separation. The success of this plant led to numerous applications for the electrostatic separation of solids throughout the world. This process was used exclusively or in conjunction with gravity separation processes (Johnson, 1938; Ralston, 1961; Lawver and Dyrenforth, 1973).

Because of its higher potential separation efficiency, having several stages/precipitator fields in series, the plate precipitator has largely replaced the tube type for dry particulates. Nowadays precipitators capable of treating 1,000 m 3 /s of gas, removing at least 99.8% of the particulates from power plants are required to meet …

A neon sign transformer is way stronger charge then the silk fabric approach. A electric generator to power the transformer and you have a different way of 'dry washing' all the way down to around 600 mesh. Try doing that with a gold pan wet or dry.....lol.
