In 1996, after the closure of the tungsten and molybdenum mining plant, the Buryat government decided to reclaim the land in Zakamensk. Not long before, Russia had passed a law on environmental protection that obliged the owners of mining enterprises to clean up polluted areas. However, the owner in Zakamensk declared bankruptcy, so all the costs of eliminating the accumulated environmental damage fell on the state. In 2005, a project was developed, and six years later, the first phase of the reclamation began.
At the same time, a new resource company emerged: Zakamensk JSC. In 2009, it received a license for the exploration and mining of minerals, including the use of waste from mining and related processing operations. It built its own concentrator in Zakamensk. It sits on a tailings dump in the Barun-Naryn area and is surrounded by 35 mln tons of slag. The company employs 200 people. Workers process the tailings and get a tungsten concentrate. The ultimate beneficiary was Federation Council Senator Akhmet Palankoev, a businessman and president of Akropol Group.
In 2011, Zakamensk JSC won an open tender for work to liquidate the accumulated environmental damage and received R500 mln from the state. Under the project, over 3 mln tons of slag from two large urban sites were to be removed and transported to the Barun-Naryn tailings dump, where in the Soviet years workers had exported contaminated slag.
