Description
Technical field
The present invention relates to Collophanite flotation technical fields, and in particular to a kind of siliceous Cellophane direct flotation collecting agent and its system
Preparation Method.
Background technique
China is phosphor resource big country, but it is largely low-grade phosphate ore without richness that phosphate rock resource is rich, wherein 80% is siliceous
And silicate mineral, major impurity feature are that high-silicon high is semi-oxidized again, the main floatation process of such ore is direct flotation or just
Reverse flotation, i.e., directly floating phosphorus desiliconization.Key factor therein is exactly the use of floating agent, and in floating agent it is most important just
It is collecting agent.
Currently, the fatty acid collecting agent for selecting collecting agent mainly based on oleic acid that top-ups.The problem of this kind of collecting agent
It is that dosage is high under normal temperature conditions, flotation efficiency is low, poor selectivity, causes flotation flowsheet long, at high cost.For this reason, it may be necessary to study
Soluble efficient direct flotation collecting agent good, collecting ability is strong.
Summary of the invention
The purpose of the present invention is to provide a kind of siliceous Cellophane direct flotation collecting agents and preparation method thereof, solve existing oil

Agent, it is characterised in that be made of the raw material of following parts by weight: 6~9 parts of triethanolamine oleate sodium, anionic surfactant 1~2
Part, 1~3 part of mixed fatty alcohol.
Further technical solution is that the mixed fatty alcohol is made by isooctanol and n-octyl alcohol in the ratio of 1:1.
Further technical solution is that the anionic surfactant is lauryl sodium sulfate, laureth sulphur
Sour sodium, sodium cetanesulfonate it is one or more.
The present invention can also be a kind of preparation method of siliceous Cellophane direct flotation collecting agent, it is characterised in that including following
Step:
1) raw material is weighed by weight: 6~9 parts of triethanolamine oleate sodium, 1~2 part of anionic surfactant, mixing rouge
1~3 part of fat alcohol；
2) it prepares: raw material in step 1) being uniformly mixed at normal temperature, siliceous Cellophane direct flotation collecting agent is made.
Further technical solution is that the mixed fatty alcohol is made by isooctanol and n-octyl alcohol in the ratio of 1:1.
Further technical solution is that the anionic surfactant is lauryl sodium sulfate, laureth sulphur
Sour sodium, sodium cetanesulfonate it is one or more.
Further technical solution is that the collecting agent effective component is 93%~100%.
Further technical solution is the collectors application in low-grade siliceous and silicate-type and mixed type collophane
When direct flotation, 1%~5% concentration need to be diluted with water to.
Compared with prior art, the beneficial effects of the present invention are: providing a kind of siliceous collophane direct flotation of simple process
Collecting agent and preparation method thereof is formed with triethanolamine oleate sodium based raw material with anionic surfactant and higher aliphatic
High concentration mix Cellophane direct flotation collecting agent, it is hydrophilic due to introducing multiple hydroxyls compared with common collecting agent enuatrol
Group, collecting agent CMC value improves 19.58 times or more, increases its dissolubility in water, it is water-soluble under normal temperature condition,
Good dispersion；Compared with common collecting agent enuatrol, the present invention in collecting agent molecular cross sectional area byIt increases toMolecular cross sectional area improves 30.81% or more, can effectively improve collophane direct flotation float phosphorus desiliconization concentrate yield and
The rate of recovery improves flotation rate, shortens flotation time.The collecting agent is produced using medicament, and beneficiation cost is low, easily realizes industry
Metaplasia produces, remarkable in economical benefits, is a kind of economic, environmental protection and the suitable efficient room temperature collophane direct flotation collecting promoted the use of
Agent.
By the collectors application in low-grade high silica gel phosphorus ore direct flotation, added under room temperature (15~25 DEG C) after dilution
0.5~0.7kg/t collecting agent, by roughing operation of once top-uping, compared with oleic-acid collecting agent, since molecular area increases,
In 3 minutes flotation times, flotation yield and the rate of recovery are respectively increased 6% and 9% or so, and flotation time shortens 40% or more,
It is a kind of efficient room temperature Cellophane direct flotation collecting agent.
