The impact of high-power electromagnetic pulses on the surface state and technological properties of the calciferous minerals
The modification of structural chemical properties of natural fluorite, scheelite and calcite under the impact of high-power electromagnetic pulses (HPEMP-treatment) were studied with help of adsorption of acid-base indicators. It was determined that the HPEMP-treatment during of 30 seconds (3 x 103 pulses) resulted in the intensification of fluorite surface 'electron-donating ability and acceptor properties of calcite and scheelite surfaces. Single mineral flotation tests has allowed to determine that treatment by high-power electromagnetic pulses resulted in the improvement of the calciferous minerals floatability. The rising of the scheelite recovery was 10 - 12%, for fluorite it was 5 - 6%, for calcite 7 - 8%.
