“…Extractability of fine and very fine gold by centrifugal concentration is investigated in the conditions of gold recovery [8,9]. With a view to assessing prospects for using energy deposition in ore pretreatment, it is attempted to analyze the known nonconventional methods of mineral processing which are targeted at enhanced disintegration of fine-dispersed granular aggregates and extraction of micro and nano particles of noble metals in the further hydrometallurgy and gravity processes [10,11].…”
