Abstract
The paper substantiates the possibility of applying the technology based on the use of electrohydraulic effect for the preliminary preparation of clay ores with fine mineral phases. The technology was developed in the laboratory by conducting experimental studies on samples of several types of clay rocks and ores that differ in the composition of inclusions of solid fractions in them. Experiments have confirmed that with the optimal selection of operating modes of a specially created electrohydraulic unit, high selectivity is achieved for crushing and dispersing different strength minerals and mineral phases of sample materials, which ensures the destruction of the clay component while maintaining the integrity of solid fractions. Removal of water-soluble clay fraction with the pulp and washing of the resulting intermediate product provides a high degree of cleaning of solid inclusions from clay. This makes it possible to recommend the use of electrohydraulic technology for cleaning solid fractions of fine clay ores from clay at the initial stage of ore preparation, followed by the extraction of valuable minerals from the resulting intermediate product of enrichment by traditional methods.
