摘要：

Placer gold mining wastes may be assumed an important source to replenish mineral and raw materials supply of the gold mining industry in Russia's Far East. The tests are carried out on samples of placer gold mine waste of gravel size and fines. The article gives mineralogical and petrographical characteristics of the samples. Admixtures of platinum, silver, titanium and iron are traced in the sample composition. Results of the gravity concentration with the preliminary magnetic separation of the samples are reported. The yield of magnetic fraction makes 39.77%, and it is found that magnetite contains titanium. Gold recovery in the gravity concentrate is 91.6% with 0.06 g/t content of platinum and 57.7 g/t content of silver.
