Title:
ELECTROSTATICALLY ENHANCED TRIBOCHEMICAL METHODS AND APPARATUS
Document Type and Number:
WIPO Patent Application WO2004018717
Kind Code:
A3
Abstract:
A milling apparatus is modified by electrically insulating the milling chamber to enhance the efficiency of tribochemical reactions between reactive compositions during milling. The enhanced level of tribochemical reactivity is attributed to the buildup of electrostatic charge in and on the milled chamber during mill operation. The insulated mills in accordance with the invention can be used in a wide variety of commercial applications generally involving tribomechanically induced redox chemistry, including ore extraction, precious metal extraction, production of ferrites and pigments, and waste processing.
