Problems solved by technology

However, since the collector uses non-ionic surfactants as raw materials, and these raw materials must be obtained through chemical synthesis, its unit price is much higher than that of fatty acid collectors from nature, and it does not have the prospect of wide application.

Embodiment 1

[0020] Put 30Kg of industrial grade lard fatty acid, 5Kg of sodium hydroxide and 55kg of water into the reaction kettle, stir at 80°C for 3h, after saponification, add 3Kg of dodecyl betaine, 2Kg of dodecylamine, fatty alcohol poly Oxyethylene ether (AEO-10) 3Kg, Tween-20 2Kg, coconut oil fatty acid diethanolamide (6501) 1Kg and continue to stir until they are evenly mixed.

[0021] The prepared reverse flotation collector is pumped into the phosphate rock slurry stirring tank and mineralized with the ore pulp. The amount added is 0.25Kg / t raw ore. After one flotation, the flotation index of the phosphorous concentrate is P 2 o 5 28.5%, MgO 0.7%, Fe 2 o 3 1.56%, Al 2 o 3 1.65%, P 2 o 5 The recovery rate reaches 87%, which meets the requirement of ore for dihydrate wet-process phosphoric acid production.

Embodiment 2

[0023] Put 30Kg of industrial grade lard fatty acid, 5Kg of sodium hydroxide and 55kg of water into the reaction kettle, stir at 80°C for 3h, after saponification, add 3.5Kg of dodecyl betaine, 1Kg of dodecylamine, Tween -20 2Kg, fatty alcohol polyoxyethylene ether (AEO-10) 3Kg, coconut oil fatty acid diethanolamide (6501) 1Kg and continue to stir until evenly mixed.

[0024] The prepared reverse flotation collector is pumped into the phosphate rock slurry stirring tank and mineralized with the ore pulp. The amount added is 0.25Kg / t raw ore. After one flotation, the flotation index of the phosphorous concentrate is P 2 o 5 28.5%, MgO 0.7%, Fe 2 o 3 1.56%, Al 2 o 3 1.65%, P 2 o 5 The recovery rate reaches 87%, which meets the requirement of ore for dihydrate wet-process phosphoric acid production.

Embodiment 3

[0026] Put 35Kg of industrial grade tallow fatty acid, 8Kg of sodium bicarbonate and 42Kg of water into the reaction kettle, stir at 80°C for 3h, after saponification, add 4Kg of lauryl betaine, 2Kg of octadecylamine, Tween-40 3Kg, 4Kg of fatty alcohol polyoxyethylene ether (AEO-15), and 2Kg of sodium dodecylbenzenesulfonate continue to stir until they are evenly mixed.

[0027] The prepared reverse flotation collector is pumped into the phosphate slurry stirring tank and the slurry is mineralized. The addition amount is 0.3Kg / t raw ore. After one flotation, the flotation index of the phosphorus concentrate is P 2 o 5 29.3%, MgO 0.68%, Fe 2 o 3 1.49%, Al 2 o 3 1.55%, P 2 o 5 The recovery rate reaches 85%, meeting the requirement of dihydrate wet-process phosphoric acid production ore.

Abstract

The invention discloses a reverse-flotation collophanite collecting agent and a preparation method thereof. The collecting agent comprises the following raw materials in parts by weight: 30-40 parts of industrial-grade animal oil fatty acid, 5-10 parts of inorganic base, 3-5 parts of dodecyl betaine, 1-3 parts of fatty amine, 2-4 parts of Tween, 3-5 parts of fatty alcohol polyoxyethylene ether, 1-3 parts of a foaming agent and 33-55 parts of water. The collecting agent provided by the invention has the advantages of good dispersing performance, low working temperature, high efficiency and the like; as compared with that of the conventional reverse-flotation magnesium-removal collophanite collecting agent, the dosage of the collecting agent provided by the invention can be reduced by about 10%.

Description

technical field [0001] The invention belongs to the technical field of collophosite reverse flotation, and in particular relates to a collophosite reverse flotation collector and a preparation method thereof. Background technique [0002] Phosphate rock is an important chemical raw material, widely used in agriculture, medicine, military, food and energy industries. Although my country's phosphate rock reserves are relatively large, compared with Morocco and the United States, my country's phosphate rock has a lower grade and relatively poor flotation performance. In addition, there are many lean ores and few rich ores in our country. Phosphate rock must be enriched through ore dressing to meet the production requirements of wet-process phosphoric acid. [0003] Generally speaking, phosphate rock is divided into carbonate type, silicate type and mixed type according to the form of its gangue. For carbonate type collophosphine, its gangue mainly exists in the form of dolomit...
