Abstract

A bulk coal sample from the Erkovetsky deposit was studied at Amur experimental and engineering complex. Separate fractions of coal combustion products (slag, fly ash and sludge) were obtained for the first time, in which the morphology, fineness of gold and the composition of inclusions were studied. A consistent decrease in gold size and content was established after coal combustion, transportation in a gas-smoke stream, and subsequent condensation. A comparative analysis of gold in the combustion products of coal and in ore bodies of the fold-mountain framing of the Zeya-Bureinsky basin was carried out, the ways of its migration to peat bogs were considered.
