Abstract

The present invention relates to one kind of mineral floating activating agent and its preparation. The mineral floating activating agent is prepared with the materials including water, gypsum, animal oil, fish oil and sodium carbonate in the weight ratio of 0.2-2 to 0.2-0.5 to 0.1-1.0 to 0.2-2.0 to 0.1-1.0 and through several technological steps. It is white water soluble powder of grain size 0.02 mm. The mineral floating activating agent is used as catalyst in sulfide mineral floating operation, and can activate collecting agent and foaming agent to reach effective separation of adhered gangue and non-sulfide mineral and ensure high floating effect.

Description

technical field [0001] The invention relates to a mineral flotation active agent and a preparation method thereof. The active agent acts as a catalyst in the sulfide flotation operation, and activates the components of the collector and foaming agent in the ore dressing to achieve more effective separation Paste gangue and non-sulfide minerals on precious gold ore to ensure selectivity, improve flotation effect, increase yield and concentrate grade. Background technique [0002] With the development of the metallurgical industry, the number of easily-selected ores gradually decreased, and the grades of ores produced by many mines were far lower than those in the 19th and 20th centuries. Some useless minerals seriously hinder the improvement of flotation technical indicators. The first ones that reduce the flotation indicators are arsenic ore, followed by pyrite, arsenopyrite, magnetite, mica, mud mica, interlayer mica, antimony, bismuth, etc. metal minerals. Therefore, the...
