Selective attachment processes in ancient gold ore …

 · In modern gold beneficiation, electrostatic separation via triboelectricity has been tested but has no practical use (Inculet et al., 1988). However, static electricity is an essential secondary effect in the winnowing or "dry washing" of gold ( Wilson, 1961 ); a dry washer separates gold from sand using an air pulse through a porous blanket of wool or other fiber that has insulating ...

Electrostatic Beneficiation of Phosphate Ores: Review of …

Electrostatic separation was of interest as an alternative to flotation from an economic standpoint due to the fact that large deposits of phosphates are found in arid regions. [13] Using laboratory-scale free fall separators with a "turbocharger", these researchers were able to obtain separation results similar to flotation processes from ores with relatively simple gangue compositions.

Electrostatic method to separate roots from soil, Journal …

 · Complete removal of roots from soil samples is a prerequisite for most of the chemical and biological analyses. A simple electrostatic method of separating roots from sieved, largely mineral soil substrates was optimized and examined by the addition of 14C labeled fine roots to sandy, silt loamy and clay loamy samples. Depending on soil texture, between 40% and 50% of fine roots can be removed ...
