Problems solved by technology

However, flotation requires a large amount of fatty acid raw materials, and most of the raw materials are expensive, the origin is far away, the dosage is large, and the components fluctuate greatly, resulting in unstable production and high cost.

Embodiment 1

[0019] A method for preparing a collophosite reverse flotation carbonate mineral collector with waste oil, characterized in that it consists of waste oil, alkali and water, and the ratio of waste oil: alkali: water = 1:0.15 in parts by mass Mix at a ratio of ~0.3:400, and react for 1 to 1.5 hours at a constant temperature of 40 to 80°C to prepare a collector for carbonate minerals in reverse flotation of collophanite. The steps are as follows:

[0020] a. Heat the waste oil to 40-80°C, filter and precipitate to remove solid waste, and then dehydrate until the water content of the waste oil is less than 1%;

[0021] b. Detect the components of waste oil, and prepare a mixture with the content of C12~C18 in the waste oil components, and the content of C12~C18 in the waste oil components accounts for about 65% of the total components;

[0022] c. Mix according to the ratio of waste oil: alkali: water = 1:0.15~0.3:400, saponify at a constant temperature of 40~80°C for 1~1.5 hours,...

Embodiment 2

[0025] Detect the components of waste oil, and adjust the content of C12~C18 in the components to account for about 75% of the total components; saponify the raw materials to obtain reverse flotation carbonate mineral collectors. When raw ore P 2 o 5 Content of 22%, MgO content of 5.6% collephosite, add 400 g / ton of raw ore reagent for reverse flotation operation, the content of MgO in the concentrate is 0.85%, and the removal rate of MgO is up to 88%.

Embodiment 3

[0027] The components of waste oil were detected, and the content of C12~C18 in the components was adjusted to about 85% of the total components; the raw materials were subjected to saponification reaction to obtain reverse flotation carbonate mineral collectors. When raw ore P 2 o 5 Content of 22%, MgO content of 5.6% collephosite, add 300 g / ton of raw ore reagent for reverse flotation operation, the content of MgO in the concentrate is 0.80%, and the removal rate of MgO is up to 90%.

Abstract

The invention relates to a method for preparing collophanite reverse flotation collecting agent with drainage oil turned into wealth from waste materials. The method comprises the steps that a. the low-quality drainage oil is heated to 40-80 DEG C, solid waste is removed by filtering and precipitating, dehydration is then carried out until water content of the drainage oil is lower than 1%; b. the component of the drainage oil is detected, blending is carried out until the content of C12-C18 in the component is larger than 60% of the whole component; c. through saponification, the pH of the drainage oil is adjusted to 11, the collophanite reverse flotation carbonate mineral collecting agent is obtained; d. 300-500g of drainage oil saponification matter is added into one ton of raw ore in industrial production of low-grade collophanite reverse flotation carbonate minerals with MgO content of 3-7%, high-quality phosphorus concentrate with MgO content lower than 1% is obtained, and removal rate of MgO is larger than 80%. According to the method, the drainage oil can be turned into wealth from waste materials for reuse, purchasing cost of flotation agent raw materials is greatly lowered, economy and environment protection are achieved, and the method is suitable for popularizing use of the drainage oil.

Description

technical field [0001] The invention relates to a chemical production method, in particular to a method for converting waste oil into valuables and preparing a carbonate mineral collector for collophosite reverse flotation. Background technique [0002] With the rapid development of the phosphate fertilizer industry, the mining and consumption of phosphate rocks have also increased sharply, and the overall grade of phosphate rocks has been declining. More than 80% of the phosphate rocks need to be flotation to obtain phosphate concentrates for phosphoric acid production. However, flotation requires a large amount of fatty acid raw materials, and most of the raw materials have high prices, far-away places of production, large dosages, and large fluctuations in components, resulting in unstable production and high costs. For this reason, it is necessary to study reagent raw materials with wide sources of raw materials, near production areas, and low prices. [0003] As a larg...
