Description
Technical field
The invention belongs to mineral metallurgical technology field, and in particular in a kind of recovery lead oxide ore the leaching method of lead and its
Leaching agent.
Background technology
Lead is important non-ferrous metal, with the increasingly increase in world wide to lead metal demand, primary lead ore
It is faced with reserves deficient, the pressure for the multiaspect such as dressing and smelting process is seriously polluted.In nature, it can be used for reclaiming the industrial mineral of lead
Sulfide mineral and oxide mineral including lead.The main galena of galena thing (PbS), if lead oxide ore owner's cerussite
(PbCO3).Vulcanized lead mineral have preferable floatability, and concentrate can be readily available using flotation, due to high-grade vulcanized lead
Ore resources are increasingly reduced, and then lead oxide ore becomes the valuable source for reclaiming lead.For the sulfide mineral of lead, oxidation
Mineral dissolution degree is larger, and hydrometallurgy is a kind of approach for reclaiming lead from lead oxide ore well.
Chemically see in nature, lead minerals and metal are soluble in nitric acid (HNO3), boron fluoric acid (HBF4), silicofluoric acid
(H2SiF6), acetic acid (CH3COOH) etc.；Hydrochloric acid only works with the surface of lead and is formed and almost do not dissolved at normal temperatures with sulfuric acid
PbCl2And PbSO4Skin covering of the surface.Therefore, using industrially conventional " three acid " as solvent, all it is less suitable for being used for wet method refining
Lead, because the PbSO of generation4、PbCl2Solubility is smaller in aqueous；And make the Pb (NO of solvent formation with nitric acid3)2In water
Less stable in solution, easily generates volatile nitrogen oxide.Here it is wet method refines the where the shoe pinches of plumbing large-scale production,
It is also that the refining of lead bullion is had to using H costly2SiF6Make the reason of electrolyte.In addition, country advocates ecological environmental protection,
Green economy is encouraged, therefore, the requirement also more and more higher to reclaiming the leaching agent of lead in lead oxide ore.
The content of the invention
The deficiency existed for above-mentioned prior art, it is an object of the present invention to provide a kind of high new recovery oxygen of leaching efficiency
Change the leaching agent of lead in lead ore.
To achieve these goals, technical scheme is specific as follows：
A kind of leaching agent of lead in recovery lead oxide ore, the leaching agent is that 5-sulphosalicylic acid and water are uniformly mixed.
In an embodiment of the present invention, concentration of the leaching agent containing 5-sulphosalicylic acid is 0.1mol/L~0.5mol/
L。
For above-mentioned prior art exist limitation, it is an object of the present invention to provide a kind of leaching efficiency it is high, simple to operate and
The leaching method of lead in the low new recovery lead oxide ore of process costs.
To achieve these goals, another technical scheme of the invention is specific as follows：
A kind of above-mentioned leaching agent of use reclaims the leaching method of lead in lead oxide ore, and this method is specially：It is to lead grade
14%~75% lead oxide ore carries out muck, ore grinding, and the percentage by weight that ore grain size is less than 65 μm is 70%~96%；Will
5-sulphosalicylic acid solution and lead oxide ore miberal powder are according to 5~20:1 quality liquid-solid ratio mixing, and be sufficiently stirred for 20min~
60min, wherein extraction temperature are controlled in 20 DEG C~60 DEG C；Obtain being adapted to next step extraction, electrodeposition with containing lead solution.
The technical principle of technical solution of the present invention：The 5-sulphosalicylic acid includes 3 functional groups-OH ,-COOH ,-
SO3H, 5-sulfosalicylic acid can partly or entirely dehydrogenation, 5-sulfosalicylic acid mainly exists with five kinds of structure types, specifically such as
Shown in lower.
If 5-sulfosalicylic acid is ionized completely in aqueous, carried out by following reaction equation (3) and (4)：
C7H6O6S(s)→C7H3O6S3– (aq)+3H+ (aq) (1)
Because the essential mineral in lead oxide ore is cerussite, following reaction side can occur in 5-sulfosalisylic acid solution
Formula (2)：
3PbCO3(s)+2C7H6O6S(s)→3Pb2+ (aq)+2C7H3O6S3– (aq)+3H2O(aq)+3CO2(g) (2)
The ionization of 5-sulfosalicylic acid in aqueous produces hydrogen ion, promotes copper oxide mineral to dissolve, this is 5-sulfo group
The acidleach effect that salicylic acid has.
The beneficial effects of the invention are as follows：The present invention by using certain density 5-sulphosalicylic acid as leaching agent, it is right
From lead oxide ore metallurgical extraction obtain contain lead solution, in reaction vessel by control optimal extraction temperature, ore grain size,
Leaching agent and powdered ore quality solid-to-liquid ratio and agent concentration is leached, lead leaching rate in lead oxide ore can be made close to 97%；And should
Leaching method does not need high temperature, pressurized equipment, and simple to operate, and process costs are low, so as to provide suitable next step lead extraction
Take with electrodeposition processing containing lead solution.
