Problems solved by technology

Due to the compression of production costs by flotation agent manufacturers, the current production of domestic flotation collectors is mostly a very simple soap production process, and many key processes that can strengthen saponification and promote product quality stability have been omitted, resulting in the market. The quality of the collector fluctuates greatly

Embodiment 1

[0009] Example 1: 70 grams of palmitoleic acid and 30 grams of cottonoleic acid required for the production of a collector for a customer in Hubei were placed in a steam reactor, stirred and heated to 80°C to completely dissolve it, and then an appropriate amount of caustic soda was added in the Saponification at 85° C. for 1 hour, then adding 5% citric acid of the total amount of raw materials, and stirring at 70° C. for 2 hours to obtain collector A. Put 70 grams of palm oleic acid and 30 grams of cotton oleic acid, which are required for the production of collectors for a Hubei customer, in a steam reactor, stir and heat to 80°C to dissolve completely, and then add an appropriate amount of caustic soda at 85°C After saponification for 1 hour, collector B was obtained.

[0010] The collectors A and B prepared in this example 1 were respectively used on the ore of the Hubei customer to carry out the reverse flotation scraping test under the same process flow and the same dosa...

Embodiment 2

[0011] Example 2: 80 grams of palm oil and 20 grams of crude bran oil, which are required for the production of collectors from a certain customer in Guizhou, are placed in a steam reactor, stirred and heated to 82°C to completely dissolve them, and then add an appropriate amount of caustic soda at 70 Saponification at ℃ for 1 hour and 30 minutes, then adding 3% citric acid of the total amount of raw materials, and continuing to stir at 85 ℃ for 1 hour and 30 minutes to obtain collector C. Put 80 grams of palm oil and 20 grams of crude bran oil, which are required for the production of collectors for a customer in Guizhou, into a steam reactor, stir and heat to 82°C to dissolve completely, then add an appropriate amount of caustic soda to saponify at 70°C Collector D was obtained in 1 hour and 30 minutes.

[0012] The collectors C and D prepared in this example 2 were respectively used on the ore of the Guizhou customer to carry out the reverse flotation scraping test under th...

Embodiment 3

[0013] Example 3: 75 grams of palmitoleic acid and 25 grams of fur bran oil, which are required for the production of collectors for a customer in Yunnan, were placed in a steam reactor, stirred and heated to 85°C to dissolve completely, and then an appropriate amount of caustic soda was added at 75 Saponification for 1 hour and 20 minutes under the condition of ℃, then adding 6% citric acid of the total amount of raw materials, and continuing to stir for 1 hour under the condition of 90 ℃ to obtain collector E. Put 75 grams of palm oleic acid and 25 grams of fur bran oil, which are required for the production of collectors for a client in Yunnan, into a steam reactor, stir and heat to 85°C to dissolve completely, then add an appropriate amount of caustic soda to saponify at 75°C Collector F was obtained in 1 hour and 20 minutes.

[0014] The collectors E and F prepared in this example 3 were respectively used on the ore of the Yunnan customer to carry out the reverse flotatio...

Abstract

The invention relates to a method capable of effectively enhancing the quality of a flotation collector product. The method comprises the following steps that raw materials needed for producing the collector are placed in a steam reaction still, stirred and heated to 80-90 DEG C to be dissolved completely; then an appropriate amount of caustic soda is added, saponification is conducted for 1-1.5 hours at the temperature of 80-90 DEG C; and 2-10% of citric acid is added, continuous stirring is conducted for 1-2 hours at the temperature of 70-90 DEG C, and the collector with the relatively high saponification degree is obtained. The method capable of effectively enhancing the quality of the flotation collector product can effectively solve the problems of incomplete saponification and substandard product quality of a collector caused by overlarge system viscosity in the saponification process of collector production.

Description

technical field [0001] The invention relates to a method for producing a flotation collector, in particular to a method for effectively improving the product quality of the flotation collector. Background technique [0002] Flotation collector is an important medium for mineral processing production, and product quality and stability are of great significance to the stability of the production and operation of the mineral processing plant. Due to the compression of production costs by flotation agent manufacturers, the current production of domestic flotation collectors is mostly a very simple soap production process, and many key processes that can strengthen saponification and promote product quality stability have been omitted, resulting in the market. The collector quality fluctuates greatly. Therefore, it is particularly urgent to develop a method that requires only a simple modification of the traditional flotation collector production process to achieve a stable impr...
