Реферат | Brown coals of Kansko-Achinsk pool (KAP), humus, groups 2БВ, low-ash, are characterized raised goldfields. At their burning the basic part of mineral components, including gold, concentrates in ashes. Last decades the basic quantity of gold is taken from solutions and pulps on carbon sorbents technology, with application of high-strength carbon sorbents with the developed porous structure. On the basis of brown coals of KAP, thanking their low-ash and to the high maintenance vitrinit in petrographic structure, the carbon sorbents which are meeting the requirements carbon sorbents technology, can be received. Industrial realization of complex processing of brown coals of KAP with reception of strong carbon sorbents with the developed porous structure will allow to introduce in region carbon sorbents technology, of extraction of gold from the solutions formed at its selective extraction by chemical reagents from ashes from burning of brown coals of KAP. In article the technological scheme of processing of brown coals of KAP, quality and scope indicators brown coal sorbents are resulted. The raised maintenance of gold in ashes from burning of brown coals of KAP, formed in large quantities, causes economic feasibility and necessity of working out of technological methods of exhaustive extraction of gold from the cindery rests. Geotechnology methods can be applied to extraction of gold from the cindery rests of burning of brown coals. Received on the basis of brown coals of KAP carbon sorbents as crushed and spherical, meet high requirements of process of extraction of gold from solutions and pulps — the big specific surface at high durability on abrasion. |
