The listing on the London Stock Exchange has been revived by its owners, Russian billionaires Andrey Melnichenko and Sergei Popov. The proposal was initially made in mid-2008, but was withdrawn following chaos in the markets.
The plan is expected to kick off a chain of mining listings, including that of Mozambique-based Ncondezi in London.
The scale of the transaction, which could involve 25% of the companies listed in London and Moscow, has drawn interest from major investment banks such as Morgan Stanley, Credit Suisse, UBS, Goldman Sachs, Deutsche, VTB and Renaissance Capital.
Funds from the listing would be used for development of projects.
This week, a second round of interviews might be conducted, with formal appointments likely to be finalised shortly after.
