Embodiment 1

[0025] The scheelite flotation collector of this embodiment is prepared from the following raw materials in weight percentage: 20% of tetrasodium sulfosuccinic acid, 25% of iquipon T, 15% of isooctyl phosphate, fatty acid Sodium 40%, weigh the raw materials respectively according to the above weight percentage, heat fatty acid sodium to 60°C-70°C, add tetrasodium sulfosuccinic acid and stir, then add iquipon T and isooctyl phosphate Stir for 1.5 hours, and stir evenly to prepare a scheelite flotation collector.

[0026] Using the prepared scheelite flotation collector, the flotation grade of raw ore is 0.45%, and the obtained tungsten crude concentrate grade reaches 1.25%, and the recovery rate is a good indicator of 88.17%.

Embodiment 2

[0028] The scheelite flotation collector of this embodiment is prepared from the following raw materials in weight percentage: 21% of tetrasodium sulfosuccinic acid, 26% of Iquipon T, 14% of isooctyl phosphate, fatty acid Sodium 39%, weigh the raw materials respectively according to the above weight percentage, heat fatty acid sodium to 60°C-70°C, add tetrasodium sulfosuccinic acid and stir, then add iquipon T and isooctyl phosphate Stir for 1.5 hours, and stir evenly to prepare a scheelite flotation collector.

[0029] Using the prepared scheelite flotation collector, the flotation grade of raw ore is 0.45%, and the obtained tungsten crude concentrate grade reaches 1.26%, and the recovery rate is a good indicator of 87.62%.

Embodiment 3

[0031] The scheelite flotation collector of this embodiment is prepared from the following raw materials in weight percentage: 22% of tetrasodium sulfosuccinic acid, 27% of iquipon T, 13% of isooctyl phosphate, fatty acid Sodium 38%, weigh the raw materials respectively according to the above weight percentage, heat fatty acid sodium to 60°C-70°C, add tetrasodium sulfosuccinic acid and stir, then add iquipon T and isooctyl phosphate Stir for 1.5 hours, and stir evenly to prepare a scheelite flotation collector.

[0032] Using the prepared scheelite flotation collector, the flotation grade of raw ore is 0.45%, and the obtained tungsten crude concentrate grade reaches 1.25%, and the recovery rate is a good indicator of 87.85%.

Abstract

The invention provides a flotation collector for scheelite and a preparation method thereof. The flotation collector forscheelite disclosed by the invention is prepared from the following raw materials in percentage by weight: 20%-40% of sulfobutanediamide acid tetrasodium salt, 20%-40% of Yijipeng, 5%-15% of isooctyl phosphate and 20%-40% of sodium aliphatate. The flotation collector for scheelite is used for scheelite flotation, has good water solubility and selectivity and high collecting capacity, and enables rough scheelite concentrate with a high grade and a high recovery rate to be obtained.

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] 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 the low temperature weather in winter, many concentrators are forced to stop production due to poor indicators, resulting in a huge waste of resources. The low temperature in winter has a great influence on the dispersion performanc...
