In March 2020, Seligdar Holding will launch a special furnace for preliminary heat treatment of gold-bearing ore of the Samolazovskoye deposit in the republic, Yakutia 24 TV channel reports with the reference to the enterprise’s press service.
“Here, we have worked out all the reserves of oxidized ore, but the bowels still contain reserves of primary ore. It is not to be enriched by traditional methods. Engineers proposed an original way – to pre-burn the ore, and then send it for further processing by heap leaching,” the company says.
It is stated that the holding plans to extract about one ton of gold from the refractory ores of the Samolazovsky deposit.
“Samolazovsky ore is considered refractory not due to sulphide gold, like the many other domestic gold miners, but because the gold it contains is submicron,” the press service explains.
According to Interfax, Samolazovsky’s reserves are estimated at 7,2 tons of gold, and based on the results of exploration, the company expects to increase it by five tons.
Seligdar Holding was created in 2008 on the basis of the same name gold-mining cooperatives and other gold mining enterprises. In terms of production, the Seligdar group is among the top 15 largest gold mining companies in Russia. Now, in addition to the gold cluster, the holding includes a tin cluster, as well as other enterprises. The holding is controlled jointly by the management and the Russian Funds group and related companies.
