The influence of different factors on the process of roasting of low-sulfur rough copper flotation concentrate in shaft furnace was investigated. A sufficiently high degree of copper extraction under autogenous roasting conditions can be reached by granulation in a mixture of lignosulfonates’ solution and 10 % sulfuric acid. Partial and generalized functions of copper extraction in solution depending on acting factors are received and corrected for restrictions on degree of the extraction that cannot exceed 100% by introduction to exponential function.
