Activated granular coal is widely used in processing plants, both in Russia and
abroad. There are two problems at Kubaka mining and processing plant (MPP) during
hydrometallurgical processing of gold-containing raw materials: loss of coal during
sorption due to partial abrasion, decrease in sorption properties and, as a result, deterioration
of coal quality as a result of clogging of pores with dissolved compounds in
the pulp. This in turn leads to a decrease in the efficiency of sorption leaching of goldbearing
ores and an increase in the cost of gold. The aim of the study is to improve
the quality of activated carbon of the GOLGCARB 207C 6X12 brand based on the use
of reduction processes in order to increase the sorption capacity. Research objectives
are as follows: development of a research methodology; determination of parameters
of changes in the kinetic properties of activated carbon; step-by-step assessment of
changes in the properties of activated carbon in the technological process; identification
of the effect of coal treatment with alternative reagents (NaOH, hydrochloric
acid, sulfuric acid, lime) on improving the quality of activated carbon. The object of
the study is activated carbons of the GOLGCARB 207C 6X12 brand used at the
Kubaka MPP (Magadan region). Research methodology and methods are as follows:
a comprehensive methodology for the study of activated carbon, laboratory studies
and pilot tests. The effect of activated carbon on the efficiency of sorption leaching of
gold-bearing ores in laboratory conditions with the approbation of a new technological
solution in semi-industrial tests has been studied. The effect of acid treatment and reactivation
of coal on its sorption properties has been experimentally proven. Optimal
conditions for cleaning the pores of coal from impurities of organic, carbonate and
sulfur-containing compounds and an increase in sorption activity were achieved by
acid treatment (replacement of hydrochloric acid with sulfuric acid) and pH control |
