Development of new modifying reagent- assisted technology for rebellious gold-bearing ores processing

Abstract

Due to ever-aggravating depletion of grade raw materials reserves lean persistent ores are involved in processing operations. Fine gold impregnations in sulphides and rock-forming minerals require increased volumes of rock masses to be mined and processed. Also, before to start dressing processes such raw materials shall be subjected to finish grinding, i.e., gravitation, flotation, cyanide leaching etc., that results in decreasing technological parameters and excess consumption of toxic flotation reagents.
