Abstract: This article about of flotation color and precious metals used are known surface active substance (SAS) — foaming agents on the basis of local secondary material cubes in enrichment separation copper-molybdenum ores Almalyk Mining Metallurgical Plant (MMP) of Uzbekistan tests were carried out blowing agent samples (HA-1, HA-2).
Keywords: metallurgical plants, foaming agents, surfactants, ores, copper, blowing agent, flotation, potassium butyl xanthate.

The results of the experiments, as well as the visual monitoring of the process of flotation showed that these agents have a foaming capability close to the standard, compared with the known T-92. At a flow rate of blowing agent 30,0 g/t, in the experiment with HA-1-foaming weaker and rougher concentrate output below 2,42% or less copper recovery in the concentrate to blister 7,86%, compared to an experiment conducted with T-92 reagent.
In the experiment where a mixture of blowing agents taken NA-1-15,0 g/t + T 92-15,0 g/t — concentrate primary lower yield (1,55%), and copper extraction below respectively — to 591%, in comparison with experiment with only one t-92-30,0 g/t. Front flotation biased towards the control of flotation: Exit the main concentrate — 2,43%, the control of the concentrate — 5.11%, copper
recovery in the control of flotation concentrate was — 23,76%.
The foaming agent HA-2 has lower foaming ability than HA-1. Results of the experiments showed the feasibility of conducting further experimental tests based on blowing agent CO ANC for the flotation of copper-molybdenum ores processed in the factory [3].
The foaming agent HA-2 has lower foaming ability than HA-1. Results of the experiments showed the feasibility of conducting further experimental tests based on blowing agent CO ANC for the flotation of copper-molybdenum ores processed in the factory.
Conclusion: Thus foaming NA-1 and NA-2 are recommended as blowing agents to further improve and implement the process in the flotation beneficia-tion of non-ferrous and precious metals.
