Problems solved by technology

At present, the flotation collectors used in phosphate rock are mainly fatty acid collectors, but there are disadvantages such as large dosage, poor solubility, high flotation temperature, and resistance to hard water, which lead to high energy consumption
Paraffinic base oil is a kind of classification by foreign companies according to the nature of crude oil and processing technology. Now it is generally classified by viscosity, but there has been no strict standard. API divided base oil into three types according to saturated hydrocarbon content, viscosity index and sulfur content in 1993. Category 5

Embodiment 1

[0024] (1) Weigh 20g of paraffin-based base oil into a 250ml three-necked flask with a thermometer, and put it into the rotor; then put the three-necked flask into a magnetic heating stirrer filled with simethicone oil, and start the rotor at a speed of 320 rpm / min, the temperature rises to 140°C. Preparation of hot potassium permanganate solution: Dissolve 0.04g of potassium permanganate (the amount of potassium permanganate added is 0.2% of the mass of the paraffin base oil) in 0.5ml of 100°C hot water in advance. Add the prepared hot potassium permanganate solution to the paraffinic base oil. After the temperature rises to 140°C, use 0.15m 3 / h air flow into the air, react for 24h, to obtain the liquid after the reaction.

[0025] (2) After reacting for 24 hours, weigh 1g of the reacted liquid into a 500ml beaker, add 300ml of deionized water, put it in a water bath, and raise the temperature to 60°C. Add 0.32 g of a 10% sodium hydroxide solution dropwise, stir well unt...

Abstract

The invention relates to a method for preparing an apatite collecting agent by utilizing paraffin base oil. The method comprises the steps of adopting the paraffin base oil as a raw material, and adding a hot potassium permanganate solution at the temperature of 125 to 140 DEG C; then feeding air while continuously stirring, wherein the air feeding amount is 0.15 to 0.20m<3> / h; and after continuously reacting for 24h, using 10 percent of sodium hydroxide for saponifying at the temperature of 60 to 65 DEG C, and obtaining the apatite collecting agent. The medicament prepared by the method provided by the invention is utilized as the collecting agent, so that apatit can be flotated at the normal temperature, and the method is simple in process and convenient to operate, and has better industrial application prospect.

Description

technical field [0001] The invention relates to a method for preparing an apatite collector by using paraffin-based base oil, in particular to the modification of paraffin-based base oil, a by-product of the petroleum industry, and belongs to the field of mineral flotation agents in mineral processing engineering. Background technique [0002] Phosphate rock is an important mineral chemical raw material and an important mineral for extracting phosphorus. Phosphorus has important applications in agriculture and industry. It can be used to make phosphate fertilizer, and it can also be used to make yellow phosphorus, phosphoric acid and other phosphates. At the same time, it can also be used in industries and departments such as medicine, food, matches, dyes, sugar, ceramics, and national defense, and has been used for more than 100 years. In recent years, with the rapid development of China's economy, my country's demand for phosphorus resources has also increased. Therefore...
