Abstract
A floatation collector of sillimanite is prepared from the acid sludge as the by-product during the sulfonation of lubricating oil additive through washing in water, separation, purification, saponification to obtain main product, addition of sodium salt of fatty acid (5-20%) and raffinate oil after sulfonation or sulfonated oil in same type (2-20%), and reaction at 60-80 deg.C for 40-90 min. Its advantages are widely available raw materials, low production cost, less environmental pollution, stable quality of product, and high selectivity and collecting ability.
Description
The present invention relates to the preparation method that a kind of sillimanite selects factory's flotation collector, is the method for feedstock production floatation collector of sillimanite to produce the by-product acid sludge that produces in the lube oil additive sulfonation process exactly specifically.
According to relevant document introduction, sillimanite selects the flotation collector of factory's employing to be generally aliphatic acid and soda soap both at home and abroad at present, and is to sort under the alkali condition of pH=8.5～9.5.As everyone knows, the primary raw material of industrial production aliphatic acid is a natural oil, and it obtains through methods such as squeezing, leaching, meltings from using animal-plant oil, as soya-bean oil, cottonseed oil, coconut oil, butter, lard, cod-liver oil etc.These greases are not only some industrial important source material, but also are indispensable materials in the daily production of people.
Method with the aliphatic acid of grease production mainly contains three kinds of methods, i.e. caustic soda Hydrolyze method, catalyzing hydrolysis method and water under high pressure solution, in the chemical industry at present the most frequently used method be the catalyzing hydrolysis method." floating agent " P95 page or leaf of publishing metallurgical industry publishing house in August, 1981 has been introduced the method that catalyzing hydrolysis prepares aliphatic acid, this method is handled in the grease wash away grease of protein and other impurity to(for) the toxic effect of catalyst with the concentrated sulfuric acid earlier, a certain amount of water of adding and catalyst are mixed in grease then, mix the back and adopt vapour cooking 20～48 hours, whole hydrolysis divides 2～4 sections substeps to carry out.The advantage of this method is to save a large amount of caustic soda, and equipment is easier.Its weak point is: the production cycle is long, complex process, energy consumption height, production cost height; Product purity is low, need reduce the yield of product through repeatedly purifying; Byproduct is many, easily causes the pollution to environment.And the aliphatic acid medicament of producing is to the poor selectivity of sillimanite flotation, flotation under alkali condition, and the gained concentrate needs embathe in 80～90 ℃ hydrochloric acid solution, has more aggravated the pollution to environment.Therefore, when adopting aliphatic acid and soda soap thereof as floatation collector of sillimanite, the production cost of sillimanite concentrate is higher, and mineral processing index is also not satisfactory.
Purpose of the present invention is exactly at the above-mentioned problems in the prior art, and provide a kind of low production cost, technology simple, to the pollution of environment little and collecting and the selectivity preparation method of floatation collector of sillimanite all preferably.
For achieving the above object, the technical scheme that the preparation method of a kind of floatation collector of sillimanite of the present invention adopts is:
The preparation method of floatation collector of sillimanite of the present invention is undertaken by following processing step: to produce the by-product acid sludge that produces in the lube oil additive sulfonation process is raw material, through washing, separate purification, saponification and major product, the mean molecule quantity of this major product is greater than 380, and content of organics is greater than 38%.Add in major product then that weight accounts for the fatty acid sodium salt of major product weight 5～20% and 2～20% sulfonation is raffinated oil or sulfonated oil of the same type,, promptly get final products 60～80 ℃ of reactions 40～90 minutes down.
The mean molecule quantity of above-mentioned major product between 420～550, content of organics is preferable greater than 40% o'clock effect.
In preparation method's proportioning of floatation collector of sillimanite provided by the invention, the optimised quantity of the fatty acid sodium salt that is added is 10～15% of a major product weight, and addition is excessive, will cause the sticking and poor selectivity of flotation pulp bubble; Addition is very few, and total dosing increases flotation cost height.The fatty acid sodium salt that adds, molecular weight is moderate, and average carbochain number better, can be any in animal, plant fatty acid soap, paraffin soap, tall oil soap, the rosin soap between 15～19, also can be several mixtures wherein.It is the best that the sulfonation that adds is raffinated oil to account for 5～8% of major product weight, and addition is very few, and the flotation pulp bubble is sticking, poor selectivity; Addition is too much, and selectivity is good, but steep crisp, the cost height.The oil product that the adding sulfonation is raffinated oil is decompression four or five line dewaxed oils, or dewaxed oil of the same type, and the sulfonation degree of oil product is between 10～60%.
Compared with prior art, preparation method of the present invention has the following advantages:
1. with the petrochemical industry by-product---producing the acid sludge that produces in the lube oil additive sulfonation process is primary raw material, raw material sources are wide, steady quality, cheap, avoid a large amount of animal and plant oil consumptions of causing with aliphatic acid, also solved the problem of environmental pollution that the chemical industry by-product causes simultaneously to a certain extent.
2. production technology is simple, and is with low cost, and the cycle is short, and the reaction time only is 40～90 minutes.
3. adopt the floatation collector of sillimanite of the inventive method preparation, flotation under the normal temperature mild acid conditions does not have corrosiveness substantially to common steel floatation equipment.Gained Floatation Concentrate Grade height, metal recovery rate is big, has fundamentally solved consumption of raw materials and the extremely serious environmental pollution problem that acidleach caused of need heating of fatty acid soaps alkalescence flotation concentrate.
4. prepared floatation collector of sillimanite is easy to use, and making up a prescription does not need any special installation, and the quality of liquid medicine of preparation is extremely stable, places under 5～80 ℃ condition and can forever use.
For describing the present invention better,, preparation method provided by the invention is described in further detail below in conjunction with embodiment:
