Abstract

The invention belongs to the technical field of mineral processing, and particularly relates to a multi-polar-group non-vulcanized ore flotation combined collecting agent and a preparation and use method thereof. The multi-polar-group non-vulcanized ore flotation combined collecting agent is prepared from the following components in mass percentage: 82-94% of 1-octoxyl 5-carboxyl para-decyl amine, 3-9% of alpha-bromo-octanoic acid and 3-9% of 3-octoxyl propylamine. The multi-polar-group non-vulcanized ore flotation combined collecting agent disclosed by the invention is used for reverse flotation of quartz with hematite iron ore, direct flotation of CaF2 with fluorite ore and direct flotation of apatite with phosphorite, is good in selectivity and high in collecting performance, and can realize effective separation of target minerals from other minerals.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, and in particular relates to a multipolar-based non-sulfide ore flotation combined collector and a preparation and use method. Background technique [0002] The "United Nations Framework Convention on Climate Change" is an international agreement to comprehensively control the emission of greenhouse gases such as carbon dioxide in order to deal with the adverse effects of global warming on the human economy and society. It is also the international community's international cooperation on global climate change issues A basic framework. my country's future economic and technological development plans will inevitably be restricted by this framework convention. Therefore, low-carbon development and energy conservation and emission reduction should be the primary considerations for future scientific and technological development. In the not-too-distant future, technological constraints on...
