Abstract
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%.
