Scheelite flotation collecting agent

Abstract

The invention provides a scheelite flotation collecting agent and a preparation method thereof. The preparation raw materials of the flotation collecting agent comprise, by weight, 10%-50% of tetrasodium N-(1,2-dicarboxyethyl)-N-octadecyl sulfosuccinamate, 40%-65% of sodium aliphatate, 0.5%-2% of water glass and 0.5%-5% of sodium fluoride. The scheelite flotation collecting agent is used for scheelite flotation, is good in water solubility, good in selectivity and high in collecting capacity, and can obtain scheelite rough concentrate with high grade and high recovery rate. The preparation method of the scheelite flotation collecting agent has the advantages of being wide in raw material source and simple in preparation process, the prepared scheelite flotation collecting agent tetrasodiumN-(1,2-dicarboxyethyl)-N-octadecyl sulfosuccinamate contains three carboxyl groups and one sulfonic acid group and is very easy to dissolve in water, an aqueous solution has a foaming effect, and thecollecting effect is fast.

Description

technical field [0001] The invention relates to a flotation collector, in particular to a scheelite flotation collector and a preparation method thereof, and belongs to the technical field of mineral flotation collectors. Background technique [0002] Although the reserves of tungsten ore resources in my country are large, they have fine particle size and many associated metals, but the poor, fine and miscellaneous deposits in the scheelite reserves account for the majority. Flotation technology is the most important beneficiation method for scheelite. In recent years Such resources are becoming increasingly depleted, and the efficient development and utilization of tungsten ore has become an important issue that must be solved to achieve efficient resource utilization. In view of the low winter temperature in a certain area, it has a great impact on the dispersion performance of fatty acid collectors in the pulp. The effect of the collector is not good for a period of time, a...

Problems solved by technology

But, the ammonium benzyl hydroxamate of this invention has low toxicity, and its production cost is higher, has limited its extensive popularization and application in mineral flotation

[0004] At present, oxidized paraffin soap, oleic acid, and sodium oleate are mostly used in industry for flotation. This process has disadvantages such as large amount of reagents, poor selectivity of reagents, and high requirements for flotation temperature.

Using this type of agent, once the slurry temperature is lower than 15°C or even 20°C, the collector is easy to form micelles, the activity decreases, and the flotation effect becomes poor, resulting in a significant drop in production indicators

In low temperature weather in winter, many concentrators are forced to stop production due to poor indicators, resulting in a huge waste of resources
