Abstract

The paper is devoted to analysis and examination of DC-80 (ДК-80) nonionic surface-active reagent based on acetylene alcohols aberrant behaviour mechanism during flotation of non-ferrous metal ores, coking coals and carbon nanomaterials. Presented are results of the properties and flotation behaviour comparison for DMIPEC (ДМИПЭК) and DC-80 allied reagents based on acetylenic alcohols. The DMIPEC and DC-80 reagents are obtained by interaction of acetylene and acetone. The main matter in DMIPEC reagent has a conjugated -electrons system, consisting of a combination of acetylene and ethylene bonds, and DC-80 molecule possesses single acetylene bond. Acetylene bond is prone to selective interaction with cations of non-ferrous and noble metals. In the view of the authors, the DC-80 reagent being a surface-active substance by diphilic molecule structure and possessing high aqueous solubility due to hydrophilic and lipophilic balance, doesn’t reveal any surface activity and hence it can be absorbed as an additional collector by means of -complexes formation on the surface of sulphides and a frother should be required for the flotation realization. However, practice of flotation has shown the effect identity of DC-80 and DMIPEC reagents. It is shown in the paper that acetylene-based reagents demonstrate properties of selective surface hydrophobization of sulphide minerals and carbonic materials and at the same time gain foaming capability. At that, selectivity and speed of flotation, quality of concentrates, increase of flotation capacity and efficiency, reduction of material capacity are provided.

This study has been carried out in the framework of Fundanental and Applied Research and Development program No. 816, under Goverment Assignment No. 2014/113.
