This article considers the types of losses of nickel with flotation tailings. There is shown, that losses of nickel with concentration tailings are constant and make up 20-25% of total content in ore. These losses are formed from opened sulphides' grains, natural joints and anthropogenic formations. Nickel is included there in silicate, sulphide and oxide forms. In authors' opinion, 45% of losses contain objective irreversible losses, substantiated by nickel inclusion into the composition of lattices of various rock-forming minerals. Content of nickel admixtures in main rock-forming mineral (serpentine) is not large. However, at the expense of mass, this mineral contains ~10% of these admixtures. The rest 55% are connected with main ore mineral - pentlandite, which explains the possibility of their decreasing. In author's opinion, losses of pyrrhotine with concentration tailings are one of important factors of Pechenga ingrained ores' concentration process. The part of released pyrrhotine grains in tailings is from 60% to 90% of its content in discharges, which corresponds about its incomplete flotation. Calculations of nickel balance on mineral phases corresponds that losses of nickel in isomorphous form with pyrrhotine are ~10% in average. However, they become significantly increased due to the pentlandite admixtures in pyrrhotine. Flocculation of pyrrhotine particles by magnetite is one of the reasons of its losses. Magnetic nickel-bearing pyrrhotine is actively blocked by slag particles of magnetite. Together with pentlandite joints, this pyrrhotine is depressed in the sandy part of flotation products. Under-extraction of pentlandite and aggregation processes of slime particles also belong to anthropogenic factors. Taking into account the modern concentration technologies, solving of concentration tailings exhaustion problem is problematic and requires some non-traditional technological solutions, such as demagnetization of ferromagnetic minerals or destruction of floccules by ultra-sound and other methods.

For the first time, the project of nickel electrolysis shop of "Severonickel" Combine foresaw the realization of one-stage purification of basic electrolyte from cobalt. Results of researches and testings have shown rather high efficiency of organization of cobalt purification process in two stages. The first stage supposed to carry out the cobalt sedimentation to concentration of 40-60 mg/dm3. Herewith, practically total amount of chlorine is spent on cobalt oxidizing, and obtained sediment is easily processed on concentrate process stage with minimal costs of sulphuric acid. The second stage supposed to carry out the deep sedimentation of cobalt with not more than 15 mg/dm3 of residue concentration in solution. The unloading pulp of candle filters was supposed to be directed in the head of the process. Together with the decreasing of sediment residue, the content of Ni3+ in this residue decreases. Residue does not make any influence on the content of obtained primary cobalt cake. The scheme was realized and has been operated in nickel electrolysis shop-1 for more than a year. Nowadays, this technology is realized in united nickel electrolysis shop. Operating scheme of cobalt purification is completed by two pachucas and candle filters' unloading pulp tank of the second stage of purification of electrolyte from cobalt. There is organized the delivery of chlorine and carbonate to the second stage. The dosed pulp is delivered from unloading tank to collector of copper-purification filtrate. There is expected that decreasing of consumptions of chlorine, calcined soda and sulphuric acid are going to be 3.4, 7.9 and 5.0 thousand tones, respectively. These consumptions should provide the decreasing of chloride, sodium and sulphate content in waste waters of shop by 3.4, 3.4 and 4.9 thousand tones per year, respectively. In comparison with the functioning scheme, increased co-sedimentation of lead in cobalt cake is very important in the periods of operating of conversion with a number of series of electrolyte nickel of N-1u (?-1?) grade (content of lead is not more than 0.0003%).

Forecasting of expected ore concentration indices is a necessary element of increasing of technological process efficiency. For this purpose, results of geological and technological mapping of deposits can be applied within efficient and prospective planning. Geological and technological mapping is provided by systematic works on researching of spatial variability of chemical and mineral contents and technological properties of ores in ore bodies. Together with the depth of occurrence, there takes place the considerable changing in relations and nature of distribution of grades in ore bodies, in comparison with superposed horizons. This changing leads to the worsening of technological properties of ores. Analysis of real volumes of ore extraction from mining units of ore bodies with analytic database formation is carried out for the purpose of definition of ore charge composition by geological and technological properties and its influence on index of nickel extraction into the finished concentrate. There is shown the sequence and methodology of analytic databases formation, calculations accomplishment and results application. The carried out calculations and analysis have shown the influence of irregularity of volumes of ore extraction from mining units in ore bodies on changeability of substantial composition parameters and technological properties of raw materials, supplied to processing at concentration plant. Application of real-time forecast on the basis of mathematical processing methods gives an efficient information about parameters of substantial composition of extracted ore, which is going to be processed at concentration plant in the nearest time (in 2-3 days). This will make it possible to carry out the opportune corrections of technological modes.
