Conclusions
The results obtained here demonstrate the promise of using technogenic and concentrated condensates of hightemperature heat carriers to perform leaching as part of the processing of copper-nickel ores. The productive solutions that were obtained have high contents of the useful components (grams and tens of grams per liter) and could be converted to the desired end products by proven methods [12].
The following problems should be addressed first in future research in this area:
-
—determination of the optimum acid composition of the leaching solution (possibly in the agitation regime), which is necessary for technical-economic substantiation of the technology and to determine the effect of the salt component;
-
—development or selection of a unit for laboratory study of leaching in the filtration regime;
-
—development of an accurate method of determining the components of interest in the productive solutions with allowance for the effect of the matrix phase and the mutual effects of the components within a broad range of concentrations
