Abstract
Diatomaceous method is purified from raw ore the invention discloses one kind, including：(1) crush：Diatomite original ore is crushed into by pulverizer powdered；(2) sieve：Powdered diatomite is sieved by vibrating screen, abandons bulky grain, forms diatomite mixed powder；(3) slurrying：In diatomite mixed powder, the sulfuric acid of lower addition 38 ± 2% is stirred continuously, is by weight sulfuric acid：Diatomite mixed powder=1: 1 dosage, heat boil 12~16 it is small when, stand 30 minutes, then press filtration；(4) lotion, drying：And the diatomite after being washed with hot water is put into dryer and is dried, and is then taken out from dryer, is packed after natural cooling, become finished product purified silicious earth.The present invention purifies diatomaceous method technique from raw ore and simply easily grasps, and the purification rate of recovery is high, is adapted to industrialized production.
Description
Technical field
The present invention relates to mineral to purify field, more particularly to a kind of that diatomaceous method is purified from raw ore.
Background technology
Diatomite is time immemorial diatom fossils waste, is widely used in building materials and chemical industry and food processing field.It is logical
Normal diatomite is in earthy discrete particles, and presence is deposited in a manner of mineral deposit, mineralizing process it, be mixed with sandstone, montmorillonite and she
The mineral material such as sharp stone, exists as impurity.Obtain cleaning diatomite, it is necessary to remove be mixed with diatomite it is miscellaneous
Matter.
The method of the common purification of diatomite at present is there is process conditions requirement height, and oxide impurity content is more, purifying
The shortcomings of degree is poor, acid consumption is big, waste acid water is seriously polluted.Diatomite after sulfuric acid-treated, oxide impurity content is also very
It is high, it is impossible to extract the diatomite of high-purity.
The content of the invention
In order to solve the technical problem that Purification of Diatomite is inefficient, effect is bad at present, the present invention provides a kind of from original
Diatomaceous method is purified in ore deposit, is comprised the following steps：
(1) crush：Diatomite original ore is crushed into by pulverizer powdered；
(2) sieve：Powdered diatomite is sieved by vibrating screen, abandons bulky grain, forms diatomite mixing
Powder；
(3) slurrying：In diatomite mixed powder, the sulfuric acid of lower addition 38 ± 2% is stirred continuously, is by weight sulfuric acid：
Diatomite mixed powder=1: 1 dosage, heat boil 12~16 it is small when, stand 30 minutes, then press filtration；
(4) lotion, drying：And the diatomite after being washed with hot water is put into dryer and is dried, then from dryer
Take out, packed after natural cooling, become finished product purified silicious earth.
Further, suitable hydrofluoric acid is added in sulfuric acid, it is sulfur acid 10~20% to obtain solution concentration, hydrofluoric acid
4~8%.
Further, drying temperature is 1000 DEG C.
Further, dispersant can also be added during the washing.
Further, the dispersant in polyacrylamide, sodium citrate, sodium tripolyphosphate any one or appoint
Anticipate and a variety of formed according to arbitrary proportion.
The obtained diatomite of diatomaceous method is purified from raw ore the present invention also provides one kind.
The present invention also provides a kind of application of diatomite in production rubber reinforcing filler, filter aid, coating or releasing agent.
Compared with prior art, the present invention has the following advantages：Purification of Diatomite method technique of the present invention is simply easily grasped,
It is high to purify the rate of recovery, the purification soil for purifying generation meets level-one soil standard, available for rubber reinforcing filler, filter aid, coating, the demoulding
Application in the production such as agent, effectively improves the utilization rate of diatomite resource, improves the economic benefit of enterprise.
Use the method for the present invention can with efficient separation, low-grade diatomite ore, obtain high-recovery and high-quality diatom
Smart soil.And it is good to the adaptability of diatomite original ore, production line flow process is short, and floor space is small, diatomite ore ore dressing easy to implement
Heavy industrialization.By the diatomite grade of the method for the present invention preparation is high, impurity is few, pure, wide application.Suitably as life
Produce pure diatomite application.
Embodiment
Below by embodiment, the present invention is described in detail.
