Abstract

Термическая обработка тугоплавких золотоносных руд осуществляется в окислительной атмосфере с добавлением топлива. Для того, чтобы снизить выделение оксида азота и двуокиси серы в атмосферу, добавляют воду или водяной пар.Международная заявка была опубликована вместе с отчетом о международном поиске.Heat treatment of refractory gold-bearing ores is carried out in an oxidizing atmosphere with the addition of fuel. In order to reduce the release of nitric oxide and sulfur dioxide to the atmosphere, water or water vapor is added. The international application was published along with an international search report.
