Embodiment 1

[0012] Implementation 1: In parts by weight, mix 0.7 parts of cottonseed acidified oil and 0.3 parts of fatty acid methyl ester raw materials, heat the mixture to 120°C, add sodium hydroxide solution and stir for saponification, control pH = 10, and use saponification Add 0.04 parts of sodium dodecylbenzene sulfonate and 0.03 parts of No. 2 flotation oil produced by Zibo Rongbang Chemical Co., Ltd. to obtain the finished product.

[0013] Normal temperature flotation test of a "Haizhou-style" medium and low-grade phosphate rock in Hubei: when the natural temperature of the slurry is 6°C, the raw ore P 2 o 5 When the concentration is 15.60%, the closed-circuit process of one coarse one fine one sweeping is adopted, the collector is 1.20kg / t, and the concentrate P can be obtained through direct flotation 2 o 5 It is 33.70%, and the recovery rate reaches 94.06%, which is a good indicator.

Embodiment 2

[0014] Example 2: In parts by weight, mix 0.8 parts of cottonseed acidified oil and 0.2 parts of fatty acid methyl ester raw materials, and heat the mixture to 110 ° C, add sodium carbonate solution and stir for saponification, control pH = 9, after saponification Add 0.03 parts of sodium dodecylbenzenesulfonate and 0.02 parts of No. 2 flotation oil produced by Zibo Rongbang Chemical Co., Ltd. to obtain the finished product.

[0015] Normal temperature flotation test of a "Haizhou-style" medium and low-grade phosphate rock in Hubei: when the natural temperature of the slurry is 6°C, the raw ore P 2 o 5 When the concentration is 15.30%, the closed-circuit process of one coarse one fine one sweeping is adopted, the collector is 1.20kg / t, and the concentrate P can be obtained through direct flotation 2 o 5 It is 34.10%, and the recovery rate reaches 93.95%, which is a good indicator.

Embodiment 3

[0016] Example 3: In parts by weight, 0.9 parts of cottonseed acidified oil and 0.1 part of fatty acid methyl ester raw materials were mixed, and the mixture was heated to 100°C, ammonia solution was added and stirred for saponification, pH=8 was controlled, and the saponified The semi-finished product was added as the standard part by adding 0.02 part of sodium dodecylbenzenesulfonate and 0.03 part of No. 2 flotation oil produced by Zibo Rongbang Chemical Co., Ltd. to obtain a finished product.

[0017] Normal temperature flotation test of a "Haizhou-style" medium and low-grade phosphate rock in Hubei: when the natural temperature of the slurry is 6°C, the raw ore P 2 o 5 When the concentration is 15.80%, the closed-circuit process of one coarse one fine one sweeping is adopted, the collector is 1.20kg / t, and the concentrate P can be obtained through direct flotation 2 o 5 It is 33.80%, and the recovery rate reaches 95.44%, which is a good indicator. .

Abstract

The invention relates to a phosphorite low-temperature foam flotation collector and a preparation method thereof. The collector consists of the following substances in part by weight: 0.7 to 0.9 part of cottonseed acidic oil, 0.1 to 0.3 part of fatty acid methyl ester, 0.01 to 0.05 part of sodium dodecyl benzene sulfonate, and 0.01 to 0.05 part of foaming agent. The preparation method comprises the following steps: mixing the 0.7 to 0.9 part of cottonseed acidic oil and the 0.1 to 0.3 part of fatty acid methyl ester; heating the mixture to the temperature of between 100 and 120 DEG C; adding alkali liquor into the mixture, stirring the mixture for saponification; controlling pH to be between 8 and 10; and adding the 0.01 to 0.05 part of sodium dodecyl benzene sulfonate and the 0.01 to 0.05 part of foaming agent into the mixture by using the saponified semi-finished product as a reference part to prepare the phosphorite low-temperature foam flotation collector. When the collector can be used in 'Haizhou type' phosphorite low-temperature direct flotation, the produced product still can achieve low sesquioxide concentrate and has higher recovery rate. Compared with the conventional 'Haizhou type' phsophorite low-temperature direct flotation collector, the collector has the characteristics of high collection capability, high selectivity, small using amount, low-temperature resistance, low mineral separation cost and the like.

Description

technical field [0001] The invention relates to an ore foam flotation collector, in particular to a phosphate rock low-temperature foam flotation collector and a preparation method thereof. Background technique [0002] From Qichun, Huangmei and Huangmailing in Hubei, through Susong and Feidong in Anhui to Jinping in Jiangsu in eastern China, there are a series of small and medium-sized sedimentary metamorphic apatite deposits, which are customarily called "Haizhou-style phosphate deposits". The shape of the ore body is mainly layered and layered, and a small part is lenticular, veined and irregular. The ore structure mainly includes granite metamorphic crystal structure, phosphorus flake metamorphic crystal structure, phosphorus flake granomorphic crystal structure, leaching residual structure and fragmentation structure. The ore structure mainly includes sheet structure and gneiss structure. According to the mineral composition of gangue in the ore, it can be roughly div...
