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
The present invention relates to the ore foam flotation collector, relate in particular to a kind of phosphorite low-temperature foam flotation collector and preparation method thereof.
Background technology
The Eastern China is from Qichun, Hubei, yellow plum, Huang Mailing, Susong, Feidong through Anhui, and the silk screen to Jiangsu is distributed with a series of middle-size and small-size sedimentary metamorphic apatites mineral deposit, is referred to as " Haizhou formula phosphorus ore " traditionally.The ore body form is main with stratiform, like stratiform, and few part is lenticular, veiny and irregular.The ore structure mainly contains granoblastic texture, phosphorus sheet blastic texture, phosphorus film clips hilllock blastic texture, leaching relict texture and cataclastic texture.Structure of ores mainly contains sheet structure, gneissic structure.Roughly be divided into phosphorite, siliceous feldspathic phosphorite, mica matter phosphorite, siliceous phosphorite, manganese matter phosphorite and white clouds matter phosphorite etc. according to gangue mineral composition in the ore.Apatite is the relict glue, crystallization is granular.Apatite is six side's short columns more, drusy aligning, and local normal remnants have collophane.Relevant scholar studies this type of phosphorus ore, and natural form, infrared spectrum and the crystal-chemical formula of comprehensive apatite can confirm that ore mineral has two types; A kind of is fluor-apatite, and another kind is little carbonate fluorapatite, and this type of phosphorus ore is easy to flotation.Many uses is fatty acid collecting agent in the flotation, and this type of medicament is micella shape mostly under the normal temperature in alkaline medium; Seldom be the active shape of swimming, for a long time, at the phosphorus ore direct flotation; Need ore pulp is heated,, obtain comparatively ideal separation index so that collecting agent keeps the dispersiveness of height.Expense is too high but ore pulp is heated.Preresearch estimates, ore pulp are warmed to 35 ℃, and the required coal of raw ore per ton is 28.4KG.Present research mainly is to concentrate in normal temperature (about the 20 ℃) flotation, is (natural temperature) flotation of not heating.But in winter, the temperature in most of mines is lower, and after the ore grinding, the temperature of ore pulp possibly cause floatation indicators to descend at 5～8 ℃.
Summary of the invention
The object of the invention is in order to overcome defective and the problem that above-mentioned prior art exists; And a kind of phosphorite low-temperature foam flotation collector and preparation method thereof is provided; Phosphorite low-temperature foam flotation collector provided by the invention goes for " Haizhou formula " phosphorus ore when being 5～8 ℃ of temperature at low temperatures; Still can produce up-to-standard phosphorus concentrate product, and the concentrate rate of recovery is high, beneficiation cost is low.
The present invention realizes through following technology:
Phosphorite low-temperature foam flotation collector; It is characterized in that: form by following substances; Each material is by weight: 0.7～0.9 part of cottonseed acid carburetion, 0.1～0.3 part of fatty acid methyl ester, neopelex and foaming agent are 0.01～0.05 part of benchmark part with the semi-finished product after cottonseed acid carburetion and the fatty acid methyl ester saponification respectively; The fatty acid methyl ester of 0.7～0.9 part cottonseed acid carburetion with 0.1～0.3 part mixed; And mixture is heated to 100～120 ℃, add alkali lye and stir saponification, control pH=8～10; Be that benchmark part adds 0.01～0.05 part neopelex and 0.01～0.05 part foaming agent with the semi-finished product after the saponification again, make phosphorite low-temperature foam flotation collector.
The preparation method of phosphorite low-temperature foam flotation collector; By weight, the fatty acid methyl ester of 0.7～0.9 part cottonseed acid carburetion with 0.1～0.3 part mixed, and mixture is heated to 100～120 ℃; Add alkali lye and stir saponification; Control pH=8～10 are that benchmark part adds 0.01～0.05 part neopelex and 0.01～0.05 part foaming agent with the semi-finished product after the saponification again, make phosphorite low-temperature foam flotation collector.
Described foaming agent is No. 2 flotation oils that Zibo chemical industry Co., Ltd of flourish nation produces.
Described alkali lye is NaOH, sodium carbonate or ammoniacal liquor.
Collecting agent provided by the invention has that collecting ability is strong, selectivity is high, consumption is few, low temperature resistant, beneficiation cost is low and use advantages such as wide; Be not only applicable to the ore dressing production of " Haizhou formula " phosphorus ore; Also can be used for the ore dressing production of various rocks phosphate in powder, and at flotation temperature during at 5～8 ℃, the phosphorus concentrate quality of being produced still reaches qualified requirement and the rate of recovery is very high; This has very important meaning for the utilization of China's low-grade in a large number " Haizhou formula " phosphate rock resource.
Collecting agent provided by the invention, its mixture, NaOH, neopelex, G 30 serial foaming agents with oil prodution industry discarded object (cottonseed acid carburetion) and fatty acid methyl ester are that primary raw material is processed, these raw material sources are wide, be easy to get; Preparation technology's flow process is simple; Easy operating, production cost is low, and the concentrate rate of recovery is high; Sesquichloride content in the concentrate is low, and beneficiation cost is low.
