摘要

An innovative approach to development of pyrometallurgical autogeneous processing of sulfide copper nickel raw stuff is proposed, which is based on radically new air blasting into melt. Spatially oriented air blasting makes it possible to combine areas of heat generation and exchange in operation space of autogeneous assembly to the greatest possible extent. In order to implement the spatially oriented air blasting a new design series of tuyeres is proposed, which provide generation of ultrasound jets outflowing at any preset angle to bath surface. Experiments with cold models and fire assemblies confirmed possibility to increase specific blasting load in two times and higher in comparison with existing methods of air blasting. The following technical effects are assumed after implementation of the scientific research results: decrease in specific power consumptions; increased time of campaign lives of autogeneous assembly; suppression of dust entrainment and reduction of emissions of sulfur dioxide into environment.
