Abstract
The present invention discloses a preparation method for preparing a fluorite flotation collecting agent, which comprises the following steps: using coarse fatty acid or mixed fatty acid as the intermediate products of the manufacture of oleic acid as a raw material; adding concentrated sulphuric acid accounting for 3% to 15% of the weight of fatty acid into the raw material to generate sulphating reaction; adding an ore dressing foaming agent accounting for 0.4% to 3% of the weight of the fatty acid into a reaction product to prepare a product. The preparation method for preparing a fluorite flotation collecting agent provided by the preparation method has low production cost. The fluorite flotation collecting agent prepared by the preparation method has the advantages of strong collection ability and good water solubility and dispersivity. The fluorite flotation collecting agent is suitable for floating fluorite at normal temperature and low temperature.
Description
The present invention relates to the preparation method that a kind of fluorite selects factory's flotation agent, specifically be exactly adopt that present fluorite factory generally adopts fluorite collector agent---intermediate products croude fatty acids or fatty acid mixed in the oleic acid production process are the method that base stock prepares the fluorite agent.
At present, both at home and abroad the fluorite flotation collector that selects factory generally to adopt is an oleic acid.Oleic acid can be the raw material processing with edible oil, but because edible oil price height and resource-constrained, thereby some producers use oil foot instead or acidifying oil is raw material processing oleic acid in recent years.The oil foot here is meant the byproduct that oily factory processing and eating vegetable and animals oils is produced, and promptly divides emulsion layer and the sediment go behind the product oil; Acidifying oil is meant that oil foot processes the resulting aliphatic acid and the mixture of hydrolysing oil not through preliminary acidification hydrolization, and acid value is 110～130 milligrams (milligram kOH/ gram samples).
The general process scheme of preparation oleic acid is: raw material oil foot or the hydrolysis under acidity or alkali condition of acidifying oil generate croude fatty acids; Behind the croude fatty acids branch vibration layer, drying dehydration, distillation, output accounts for the fatty acid mixed of croude fatty acids amount 85%, produces simultaneously to steam at the bottom of the byproduct still to stay thing; Fatty acid mixed is through freezing squeezing, output final products oleic acid, and its output accounts for fatty acid mixed amount 65%～75%, simultaneously output by-product solid acid.
Find out from the technological process of above oleic acid production, the cycle that oleic acid is produced is long, distillation and freezing squeezing energy consumption are big, and very low or lower bottoms and the solid acid of two kinds of value of output, final products oleic acid accounts for the ratio of initial intermediate products croude fatty acids and only has an appointment 50%～65%, this just makes the price of oleic acid become expensive, thereby has increased the production cost that uses the fluorite factory of oleic acid.Moreover, some producer is because of freezing squeezing imperfection, and often output contains the more oleic acid of solid acid, adopts this oleic acid to make fluorite collector agent, under cryogenic conditions, and the remarkable variation of sorting result, collecting ability descends significantly.
Purpose of the present invention be exactly at oleic acid in the problems referred to above of producing and in fluorite is used, existing, and a kind of low production cost, the medicament collecting ability that propose are strong, are suitable for the preparation method of the fluorite agent of flotation at low temperature.
The preparation method of fluorite agent of the present invention is undertaken by following technology, step; Intermediate products croude fatty acids or fatty acid mixed with oleic acid production are raw material, its acid value should be greater than (165 milligrams of KOH/ gram samples), content of unsaturated acid 〉=80%, adding weight to it is the concentrated sulfuric acid of fatty acid wt 3%～15%, control reaction temperature at 20 ℃～40 ℃, 40～90 minutes reaction time; After sulfating reaction finishes, through wash, leave standstill, branch vibration layer, add the foaming agent for ore dressing that weight is fatty acid wt 0.4%～3% again, mixing promptly becomes finished product.
The preparation method of fluorite agent provided by the invention is when institute's enriching sulfuric acid amount is that 5%～8% of fatty acid wt is the best.Addition is excessive, and the finished product foamability is too strong, and selectivity descends; Addition is too little, and then sulfating reaction is insufficient.Add 0.5～1% of the preferential selected fatty acid weight of foaming agent for ore dressing.Addition is excessive, and then foaming characteristic is too strong, the selectivity variation; Addition is too small, has then reduced the collecting performance of medicament.
The foaming agent for ore dressing of above-mentioned adding can be a kind of in alcohols such as terpenol, polyalcohols ethers such as polypropylene glycol ether, oxygen alkanes such as the triethoxybutane, or with other foaming agents that above-mentioned a few class foaming agent for ore dressing have similar quality, be all present technique field those of ordinary skill and know.Preferentially select No. 2 oil of foaming agent for ore dressing (alcohols, Main Ingredients and Appearance and effective ingredient are terpenol) of extensively selling in the market for use.
Compare with the oleic acid production method, adopt method provided by the invention to prepare the fluorite agent, have the following advantages:
(1) needn't discharge the cheap by-product of value, maximally utilise raw material, reduce production cost.
(2) the fluorite agent of the present invention's production, its processing technology compares with oleic acid preparation technology, with 40～90 minutes sulfating reaction, replaced drying and dehydrating, the distillation of system oleic acid, the long period of freezing squeezing, reduce energy consumption significantly, thereby reduced cost.
(3) adopt sulphation to handle, make the part unrighted acid generation sulfating reaction in the raw material.Sulfating product is introduced sulfate group, can increase the absorption of medicament to ore, thereby increase the collecting performance of medicament.Sulfating product is water-soluble better, and it and low-melting foaming agent join in the fatty acid molecule arrangement together, have increased the emulsifying dispersivity of medicament in ore pulp, have increased the coverage rate at mineral surfaces, has also just increased the collecting ability of medicament greatly.
(4) adopt the fluorite agent of this method preparation, water-soluble, better dispersed because of its emulsification and solubility property are improved, thus be suitable for flotation fluorite under normal temperature or low temperature.
Below in conjunction with embodiment, method provided by the invention is described in further detail.
