Abstract

The research of chemical zoning of ore deposits in all types of ores of copper-nickel sulfide deposits "Zapolyarnoe". Within the field of sulfide copper-nickel ores "Zapolyarnoe" are the following types of industrial ores: 1. Rich disseminated ores representing disseminated mineralization in peridotite. 2. brecciated ore, formed by detrital material. 3. Poor disseminated ores are characterized by vein - disseminated mineralization. 4. The solid ore is a massive release of sulphides. Working on the basis of operational and detailed intelligence data. We have been carried out on samples grading of ore types. The results allowed the display of the regression line and its formula for linear dependencies. Analysis of the graphs shows that for all types of ores based copper and cobalt from the nickel content straight, and in densely disseminated and breccia types are similar, but differ greatly distracted disseminated. It is clearly seen that the ratio of copper and nickel in the ore body significantly affect scattered disseminated ores, whereas the ratio of cobalt and nickel is mainly determined by those in the heavily brecciated and disseminated ores. Dependencies among nickel, cobalt and copper in the ores do not remain constant when changing the concentration of nickel in the ore. The same graph shows that Ni / Cu ratio in breccias and diffusely disseminated ore, as well as near ore metaperidotitah substantially constant at different contents of nickel, an average of 2: 1 and 1.5, respectively, and in densely disseminated ore was a trend of increasing ratio with increasing nickel content. Ni / Co increase with increasing Ni concentration relation-ship in all types of ores. The rich ores of growth occurs at speed curve, and in breccia - a straight line. The results will help in the future to calculate reserves of operational units and plan monthly, quarterly and annual plans for the extraction of metals.
