The modern state of complex processing technology for widely-used ores was analyzed, and the main ways of their development were defined: methods of selective opening of polymineral complex joints with sequent free minerals' excreting in finished concentrates; intercycle operations; intensive finishing of concentrates and hardly-separated products by individual schemes and modes using different selective collectors, modifiers and their combinations in flowsheet operation process; hydrometallurgical processing methods for sulfide polymetallic products. The issues of rational environmental management were discussed on the example of pyrrhotine copper-nickel and pyrite copper-zinc ores which are complex and difficult for concentration. Analysis of state and development of refractory ore processing technics and technology is shown in Russian and foreign practice. The reasons of valuable mineral losses in dump waste products of various concentrates are also shown. The main technological disadvantages in scheme and dressing mode improvement are discussed: solutions and ways of indicator growth for complex refractory ore processing are defined. Efficiency of complex mineral processing technologies is mainly defined by the following factors: mineral resources quality; level of fundamental investigations of physical-chemical and technological properties of separated minerals; modern and high-productive equipment in concentration plants; production and application of wide range of selective flotation
agents; control and management of technological process; level of training of researchers, technologists, designers etc.
