Embodiment
The method and apparatus that iron is removed in a kind of zinc abstraction technique, the manganese powder adding method is in solution of zinc sulfate exit
Add manganese powder, its adding conditional be temperature be 70 DEG C, pH value be between 2.5 ~ 3.0.
Further, the pipe of solution of zinc sulfate is lengthened to outside workshop before manganese powder warehouse.
Further, deironing apparatus includes in zinc abstraction technique：Frame 1, mono beam overhead crane 101, color steel tile roof truss 102 plus powder
Platform 2, hoisting port 201, hopper 202, disk feeder 203, chute 204, mixing channel 205, the middle part of frame 1 are provided with
Plus powder platform 2, described to add the one end of powder platform 2 to be provided with hoisting port 201, the other end of described plus powder platform 2 is provided with hopper
202, the lower end of hopper 202 is provided with disk feeder 203, and the disk feeder 203 passes through chute 204 and mixing channel
205 connections, the mixing channel 205 is connected with solution of zinc sulfate outlet；
The top of frame 1 is provided with mono beam overhead crane 101, and the mono beam overhead crane 101 is driven by motor, and the top of frame 1 is set
It is equipped with color steel tile roof truss 102.
The general principle of the present invention：The pipe of solution of zinc sulfate is lengthened to outside workshop before manganese powder warehouse, passes through motor
Mono beam overhead crane 101 is driven, manganese powder bag is risen to from hoisting port 201 plus powder platform 2, then passes through hopper 202 and hopper
The conveying manganese powder of the continuous uniform of disk feeder 203 of 202 lower ends, last manganese powder is entered in mixing channel 205 by chute 204；
Because the outlet of mixing channel 205 and solution of zinc sulfate is connected, the temperature for now controlling mixing channel 205 is 70 DEG C, pH value is 2.5 ~ 3.0
Between, the ferrous ion of solution of zinc sulfate fully reacts to form ferric ion with manganese powder, under the conditions of temperature and pH value from
And make the oxidation of manganese powder fully play out, therefore manganese powder consumption than relatively low；Plus the pipe solution of zinc sulfate
Son is lengthened to outside workshop before manganese powder warehouse, therefore reduces manganese powder pollution, improves working environment；And manganese powder is applied to add
Adding system, improves production efficiency.
Embodiment is named, the present invention is further illustrated with.
Embodiment
The decline of the grade of ore, along with the increase of manganese powder consumption.By the grade of ore 20-22 at the initial stage of founding the factory when, often
Individual manganese powder consumption on duty is 500 kilograms -1 ton；The grade of ore drops at 13 points till now, each manganese powder consumption on duty
For 8-10 tons.With the more and more higher of impurity content in raw ore, the manganese powder of input is also more and more.Group member counts
Manganese powder consumption in 2012.Such as following table：
1 2012 years manganese powder consumptions of table
Solution of zinc sulfate in grader with ore pulp after mixing, and temperature now is 45 DEG C, and pH value is 5 or so, with existing
Condition remove iron, 3000 milligrams of iron of iron content in every cubic metre of solution are dropped to 20 milligrams, it is necessary to 2.4-2.3 kilograms of manganese addition powder.
The need for flow could being met.The following is experiment table：
The temperature of table 2 is 45 DEG C, and pH value is 5 or so manganese powder additions
Solution of zinc sulfate and the mixed solution of ore pulp are warming up to 55 DEG C by group member, and pH value is 5.0, add manganese powder except iron, examination
Test result such as following table：
The solution of table 3 is warming up to 55 DEG C, and pH value is 5.0, manganese powder addition
From the point of view of the result of analysis of experiments 2, mixed solution temperature be 55 DEG C, HP values it is constant in the case of, every cubic metre is contained
3000 milligrams of iron drops to 20 milligrams, it is necessary to add 2.1 kilograms of manganese powder.
Solution of zinc sulfate and the mixed solution of ore pulp are warming up to 70 DEG C by group member again again, and pH value is transferred to
Between 2.5-3.0, add manganese powder and remove iron, result of the test such as following table：
The solution of table 4 is warming up to 70 DEG C, and pH value is between 2.5-3.0, manganese powder addition
It can be seen that as long as the temperature of solution reaches 70 DEG C, pH value is transferred between 2.5-3.0, then only need to add 1.4 ㎏ manganese powder just
3000 milligrams of full iron contained in every cubic metre can be reduced to 20 milligrams.That is it is molten after the mixing of analysis 1 and analysis 2
Liquid does not reach the temperature and acidity of oxidation required for manganese powder, and input manganese powder is no in solution to be oxidized completely.
Group investigates and discussed more than and analyzes, and determines a kind of new manganese powder adding method of research, is ensureing Fe contents
On the premise of every cubic metre≤20 ㎎ and the not underproduction, the consumption of manganese powder drops to monthly 720 tons by monthly 886 tons.
Added in ball mill outlet transfer tank.Group has spot-check on April 2nd, 2013 to the ball mill outlet of 8 classes on the 7th
Locate solution of zinc sulfate and the mixed temperature of ore pulp and acidity such as following table：
Solution of zinc sulfate and the mixed temperature of ore pulp and acidity at the ball mill outlet of table 5
Show that addition manganese powder is inadvisable in ball mill outlet transfer tank by this table.Because the zinc sulfate at ball mill outlet
Solution and ore pulp are mixed, and neutral temperature only has 45 DEG C or so, and pH value is 5.0, do not reach the optimum oxidation of manganese powder oxidation
Temperature and acidity.
Directly in the addition of solution of zinc sulfate exit, it is molten to 8 class's zinc sulfate on the 16th that group has spot-check on April 9th, 2013
Temperature and the pH value such as following table in liquid exit：
The temperature and pH value in the solution of zinc sulfate exit of table 6
Manganese powder has been reached by the outlet temperature that can be seen that solution of zinc sulfate to the investigation result of 8 classes on the 16th April 9
Optimum oxidation temperature 70 C, pH value are also between 2.5-3.0.Because solution of zinc sulfate is directly to be sent from leaching workshop,
Before the ore pulp mixing with preparation room, the temperature of adjusting slurry is at 70 DEG C-75 DEG C, and pH value is also between 2.5-3.0.Institute
Directly to add manganese powder in solution of zinc sulfate exit, the addition of manganese powder can be effectively reduced.
On May 15th, 2013 is installed after manganese powder add-on system, after the completion of carried out the examination manganese addition powder of 15 days and tried
Test as follows：
Table 7 is installed after manganese powder add-on system, temperature 70 C, the pH value also manganese powder addition between 2.5-3.0
By this 15 days test as can be seen that solution temperature for 70 DEG C, pH value between 2.5-3.0, all reached manganese powder
Optimum oxidation temperature and acidity.As long as 3000 ㎎ iron contained in every cube can just be dropped to 20 ㎎ by 1.4 ㎏.
Group's manganese powder quantity such as following table consumed since having counted from June, 2013 to November：
Consumed manganese powder quantity since table 8 June to November
It can be seen that by the effect before and after above statistical form and installation manganese powder add-on system and the pipe of solution of zinc sulfate be lengthened to car
Between before the manganese powder warehouse of outside, add manganese powder with new manganese powder add-on system, not only reach the temperature and pH value of solution of zinc sulfate
The optimum oxidation temperature and acidity of manganese powder, so that the oxidation of manganese powder fully plays out, is added by each monthly average
886 tons of manganese powder drop to it is average monthly plus 590 tons can just meet production, 720 tons of the desired value than formulation in the original plan is also reduced
130 tons.
