Problems solved by technology

At present, there are certain problems in the cyanogen gold tailings treatment process. The biggest problem is to find a "temporary tailings pond" for tailings treatment in the concentrator, that is, it is impossible to realize "tailing-free" discharge; and because gold minerals are mainly enriched In sulfur concentrates, and in the sales process of sulfur concentrates, gold is generally not priced and cannot be recovered effectively, which affects resource utilization and reduces the economic benefits of production
[0004] Chinese patent "A Gold Extraction Process for Cyanide Tailings Containing Primary Sulfide Encapsulated Gold", patent application number 2006100465324, which discloses only the gold extraction method for tailings, and a large number of tailings still need to be stored after gold extraction mine pools, without development and utilization, not the comprehensive utilization of tailings, the waste of resources is still huge

Embodiment Construction

[0022] The raw ore of embodiment sorting is a kind of tailings after gold-containing oxidized ore cyanogen gold, wherein mainly contains valuable components such as iron, sulfur, gold, and its raw ore grade is:

[0023] Au 1.13g / t, Ag 17.70g / t, TFe 34.30%, S 8.79%.

[0024] First adjust the pulp concentration to 18-20%, then add activator H 2 SO 4 1000g / t and CuSO 4 300g / t, add collector (butyl xanthate + diesel oil) (1:1) 200g / t, foaming agent 2 # Oil 30g / t is used for sulfur roughing, and the sulfur rough concentrate obtained by roughing is subjected to a blank beneficiation; after sulfur roughing, two sweeps are carried out, and the dosage of the first sweeping agent is: activator CuSO 4 100g / t, collector (butyl xanthate + diesel oil) (1:1) 200g / t, foaming agent 2 # The oil is 10g / t, and the agent dosage for the second sweep is: collector butyl xanthate 20g / t. The closed-circuit selection results are shown in Table 2:

Abstract

The invention relates to the recycle of tailings of oxidized ore containing gold with high content of sulfur and iron after cyaniding and gold extraction, in particular to a recycling and processing method of gold-cyaniding tailings. The invention uses the technology of flotation of sulfur, acid preparation with sulphur ore concentrate and gold extraction and iron obtaining by cyaniding acid sludge, magnetizing roasting and magnetic separation for obtaining iron and of selection sulfur tailings after dehydration as additive in cement to realize recycling of the gold-cyaniding tailings, realize single separation and final no-tail of gold mineral and provide the route of proper technique for recycling the gold-cyaniding tailings. The invention has the advantages of low processing cost and wide application range and is a recycling technique of the gold-cyaniding tailings, which is economic, simple and applicable and has good processing effect.

Description

technical field [0001] The invention relates to the recovery and reuse of gold-containing oxidized ores with high sulfur and iron content after gold extraction by cyanidation, in particular to a recovery and treatment method for gold cyanide tailings. Background technique [0002] With the continuous development and utilization of resources, the reserves of resources on the earth are becoming less and less, but a large amount of waste generated during the production, development and use of resources is threatening the environment of human life and affecting human life. The treatment, disposal and comprehensive recycling of these wastes have very important economic and social significance, and the comprehensive recycling of useful components in waste is particularly important. The comprehensive recovery and utilization of valuable mineral resources in the tailings of the concentrator is also forced by the situation and the general trend. [0003] At present, the development ...
