Placer deposits of gold, platinoids, tin, diamonds, rare metals and the titan are known in the Arctic region of Russia. Many of the objects are exploitated already more than half a century and so far are in large part developed, while the remained resources are presented by the objects reaching scales of large-scale and average deposits. The following directions are necessary for developing of the objects: 1 – a research of capacity of the developed areas on nonconventional types of placer deposits; 2 – using of new methods of maning and enrichment of traditional placers relating to potentially economic on mining conditions (borehole hydroproduction, sea drags, application of solid ore schemes of processing for placers, etc.); 3 – search of traditional types of placer deposits in the low-explored areas.
The research of the processes of forming of technogenic placer deposits, use of new technologies of production and enrichment, also as search and prospecting on the shelf and in the low-explored areas allow to increase mineral reserves of the Arctic region.
