Abstract
The invention relates to a technology and equipment for purification of naturally impure realgar ore by sealed smelting. The method includes: crushing naturally impure realgar ore, then placing it in a sealed smelting tank, conducting heating to melt the arsenic sulfide (AsS) in the ore into an ore solution and boiling the solution into ore gas, and making the ore gas enter an adjacent condensation tank through a conduit so as to be reduced into bright orange red realgar with high purity. The product quality meets the national standard WMB9-60. AsS is greater than or equal to 90%, and AS2O3 is smaller than or equal to 0.4% (arsenic). A smelting distillation tank is cast into a barrel shape from temperature-resistant, anti-corrosion and nickel-containing pig iron. The top of the smelting distillation tank is provided with an ore inlet, the bottom of the smelting distillation tank is provided with a slag outlet, and the middle part is provided with an ore gas conduit. The smelting distillation tank is also connected to the cooling reduction tank. During smelting, the ore inlet, the slag outlet and a product outlet are all sealed. During smelting purification, the extraction rate can reach 95%, and no environmental pollution is caused.
Description
Technical field
The present invention relates to a kind of arsenic disulfide close smelting arsenic disulfide purification techniques and equipment that realgar ore impure nature (containing orpiment ore, as follows) is purified by smelting
Background technology
At present, known by the method for the unique purification of realgar stone impure nature, only have gravity treatment and flotation by ore dressing industry.But there is defect.
(1), the impure height of product realgar concentrate, red arsenic (AsS) content is difficult to praise standard WMB9-60 to portion, AsS >=90%, As2O3 (arsenic)≤0.4%
(2), mine tailing, flotation tailings water, easily contaminate environment.
(3), can not change raw ore product colour after ore dressing.
(4), mineral processing circuit complexity, equipment is many, the rate of recovery low (difficulty reaches 95%), and contain beneficiation reagent in concentrate affects quality product.
Summary of the invention
In order to overcome, existing in the time that ore dressing is purified, casting yield is lower, and quality product is difficult to reach the pharmaceutical standard of high purity, and flow process complex apparatus is many, unique purification arsenic disulfide such as environmental pollution method.It is a kind of by smelting purification arsenic disulfide Processes and apparatus that type of the present invention provides, not only break of all times, when fire is smelted arsenic disulfide, its product must be the traditional technology of arsenic, and percentage extraction, quality product AsS reach more than 95%, its color is all orange redness, and equipment, flow process are simple, do not add other medicaments, non-environmental-pollution.
Type of the present invention solves the technical scheme that its technical problem takes: utilize nature realgar ore, and after heating, the physical properties of the volatile one-tenth of realgar (A sS) ore deposit gas (A sS).By nature realgar ore, be placed in the smelting pot of sealing, heating, realgar in ore is flowed out from ore, and evaporate into ore deposit gas (AsS) and enter the conduit of smelting pot, entered cooling (drainer sprays water coolant outward) in the condensation reduction tank being connected with smelting pot by conduit outward and be reduced to the red realgar of high purity orange.
Smelt (distillation) tank and be and cast barrel shape tank, condensation with anticorrosion heatproof nickel-contained pig iron and reduce the thick iron sheet of tank and make.When smelting, the temperature of smelting pot is controlled at 500 ℃～600 ℃, the iron ore feeding hole of smelting pot, and slag notch, the products export of reduction tank is totally-enclosed.
The above-mentioned technique orpiment of can purifying
Type beneficial effect of the present invention is: product reaches high purity, and percentage extraction can be more than 95%, non-environmental-pollution, and equipment is few, and flow process is simple, and product colour is good.

Embodiment
Smelting pot (1) is suspended in stove (17), slag notch (10) stretches out furnace wall, condensation reduction tank (4) is put outside stove (17), airway (2) is connected with smelting pot airway (2), by raw ore (5) after crusher (5) fragmentation, enter sieve (6), sieve+25mm, return to fragmentation, enter again in smelting furnace (1) and smelt, again by slag notch (10), iron ore feeding hole, the reduction tank steam orifice (18) that discharges water, products export (9) sealing, furnace coal, when air blast is warmed to 500 ℃～600 ℃, ore deposit gas is reduced into high purity product (9) in drainer
Claims (3)
1. a close smelting arsenic disulfide purification techniques and equipment, it is by smelting pot, condensation reduction tank, smelting furnace composition, it is characterized in that: utilize in nature realgar ore, after realgar (AsS) is heated, volatile physical properties, realgar ore impure nature is placed in to the smelting pot of sealing, heat, make the realgar (AsS) in ore be molten into ore deposit liquid, and seethe with excitement for ore deposit gas, the cooling reduction of condensation reduction tank that ore deposit gas enters outside smelting pot by the conduit in smelting pot becomes high purity realgar.
2. according to claim 1, type of the present invention, is characterized in that: smelting pot heatproof, anticorrosion nickel-contained pig iron is cast barrel-shaped.When purification, in tank, temperature is controlled at 500 ℃～600 ℃.
3. this Processes and apparatus orpiment of purifying equally, quality product (AsS), percentage extraction reaches more than 95%, and non-environmental-pollution.
