A kind of iron-removing concentrating process of potassic feldspar belongs to ore-dressing technique.It comprises conventional crushing process and sieving technology, also comprise and wash mud, sorting, selected, purify, with the smart powder of sulfuric acid washing, the smart powder craft of screening potassium, sub-elect silt, iron, mica material according to processing step, byproducts such as di-iron trioxide and tri-iron tetroxide obtain iron content at last and are lower than 0.24% finished product.To smart powder, the rate of recovery reaches more than 90% from raw ore in the present invention; Its technological process is simple, and is easy to operate.The byproduct kind of production and processing in this technology is many, all is the primary raw material that industry needs, the resource utilization height.Whole technology is not provided with the silt storehouse, and minimizing occupies cultivated land, closed circulation production, the problem that does not stir up a cloud of dust; Industrial water recycles, the amount of conserving water, protection environmental resource.
Description
Technical field
The present invention relates to a kind of ore-dressing technique, specifically a kind of iron-removing concentrating process of potassic feldspar.
Background technology
The beneficiation method that is used at present potash feldspar deferrization both at home and abroad mainly is magnetic separation and flotation.As Geju City, Yunnan potash feldspar ore, he adopts the choosing of dry powder magnetic force, although its easy processing, its technological process is aging, and is outmoded, the processing cost height, power consumption is big, and profit is few, and usefulness is low, the product dullness, byproduct can not fully utilize, and one meets wind slightly, stirs up a cloud of dust, and air pollution is serious.The Hubei potash feldspar ore adopts flotation, and its weak point is, need add chemical substance, the production cost height, and serious waste of resources, environmental protection efficacy is poor.
Summary of the invention
Goal of the invention of the present invention is exactly at the above-mentioned defective that exists in the prior art, provides a kind of technology simple science, and production cost is low, and sealing is produced free from environmental pollution, produces the iron-removing concentrating process of the high potassic feldspar of multiple byproduct comprehensive utilization ratio.
Realize the foregoing invention purpose by the following technical solutions: a kind of iron-removing concentrating process of potassic feldspar, it comprises: with the potassic feldspar crusher in crushing, broken material is sent into the rotary screen screening, granularity is that the particle below 6 millimeters is sent into grinding machine and ground to form 20-200 purpose fine powder, also comprise following processing step
A, wash mud: 20-200 purpose powder material is sent into spiral chute, separate sorting, select silt;
B, sorting: the material that will remove silt after sorting is sent into shaking table, washes out di-iron trioxide;
C, selected: the material that will remove di-iron trioxide is sent into the strong magnetic gravity concentrator of 1024 types and is carried out selectedly, selects iron, mica material, then material is sent into the general magnetic separator of 1018 * 2 types, selects iron, mica material once more;
D, purification: will send into the high frequency shale shaker screening through the material of gravity treatment and general election, and reject di-iron trioxide and tri-iron tetroxide in the material powder, and obtain the potassic feldspar fine powder;
E, the smart powder of pickling: use sulfuric acid as mordant, blend according to the concentration of sulfuric acid and the iron-holder of potassic feldspar fine powder, under the situation that sulfuric acid concentration is determined, the iron-holder of potassic feldspar fine powder is directly proportional with the sulfuric acid weight that is added, thoroughly remove di-iron trioxide and tri-iron tetroxide through pickling, isolate copperas solution, obtain the smart powder of potassic feldspar;
F, the smart powder of screening potassic feldspar: the smart powder of potassic feldspar is sent into the screening of 20-200 mesh sieve, and screenings is that iron content is lower than 0.24% finished product.
According to technique scheme, compared with prior art, to smart powder, the rate of recovery reaches more than 90% from raw ore in the present invention; Its technological process is simple, and is easy to operate.The byproduct kind of production and processing in this technology is many, all is the primary raw material that industry needs, and the resource utilization height reaches the purpose of comprehensive utilization.It is also advantageous in that significantly whole technology is not provided with the silt storehouse, and minimizing occupies cultivated land, closed circulation production, the problem that does not stir up a cloud of dust; Industrial water recycles, the amount of conserving water, protection environmental resource.
The specific embodiment
The invention is further illustrated by the following examples:
Potassic feldspar adopts Qianxi County, Hebei province and the domestic potassic feldspar of Zunhua County, and essential mineral content (weight) is: potassic feldspar is more than 90%, annite 2%, iron 5%, kaolin 2%.
Concrete processing step is as follows:
By ore dressing routine operation method with potassic feldspar with 500 * 700 crusher in crushing, it is broken once more that broken material is sent into 135 hammer-crushers, particle after the fragmentation is sent into 1.2 * 3.6 meters rotary screen screening, the undersize degree is that the particle below 6 millimeters is sent into 1.83 * 7 meters grinding machine and ground to form 20-200 purpose fine powder, and its fineness is selected according to customer requirements.
Also comprise following processing step,
Wash mud: 20-200 purpose material is sent into 1.2 * 4 * 40 spiral chute, and material per ton adds 6 tons of water and separates sorting, selects byproduct silt (kaolin);
Sorting: the material that will select behind the silt is sent into 2.5 * 6 * 25 meters shaking table, washes out Fe

Selected: as will to wash out Fe through shaking table
2O
3Material send into the strong magnetic gravity concentrator of 1024 types and carry out selected, material is that to carry out wet high-intensity magnetic under the field intensity of 8000-10000 selected in magnetic field intensity, select byproduct iron, mica material, then material is sent into the general magnetic separator of 1018 * 2 types, be that to carry out magnetic under the field intensity of 1200-1600 selected in magnetic field intensity, select iron, mica material once more;
Purify: will send into 2.4 * 3.2 * 4 meters high frequency shale shaker screening through the material of gravity treatment and general election, screenings is the potassic feldspar fine powder, and oversize is byproduct Fe
2O
3And Fe
