Abstract
The invention discloses a hydrometallurgy reactor and hydrometallurgy method capable of improving the target element leaching rate. The hydrometallurgy reactor comprises a reactor body and a stirring device, top air inlet pipes stretching into the lower end inside the reactor body are distributed on the top of the reactor body, bottom air inlets are distributed in the bottom of the reactor body, and side face air inlets are distributed in the side face of the rector body. In the hydrometallurgy experimental study and industrial production process, due to the facts that a reaction medium is large in viscosity and small in density, and the density of metallic mineral is large, a solid body sinks to the bottom quite easily, the gas phase, the liquid phase and the solid phase are in insufficient contact, and the metallic mineral conversion rate is reduced. Due to the adoption of the reactor design capable of enhancing the mixing and mass transfer effect of the gas phase, the liquid phase and the solid phase, the aims that the target element leaching rate is higher, and the leaching rate is improved by 10 percent to 50 percent compared with the leaching rate in the traditional technology can be achieved.
Description
Technical field
The invention belongs to technical field of wet metallurgy, especially a kind of reactor and method that improves hydrometallurgy process object element and turn the rate of soaking.
Background technology
Hydrometallurgy is exactly metalliferous mineral raw material carries out chemical treatment or organic solvent extraction, separating impurity, extraction metal and compound thereof process at the aqueous solution of acidic medium or alkaline medium.Modern hydrometallurgy has almost contained all metal smeltings except iron and steel, and its whole smelting technologyes of some metals belong to hydrometallurgy, adopts wet processing but great majority are mineral decomposition, extraction and removal of impurities.
Hydrometallurgy comprises the following steps: 1. useful component in raw material to be proceeded to solution, i.e. leaching; 2. leach solution and separate with residue, simultaneously by the solvent for metallurgy and the metal ion washing and recycling that become entrained in residue; 3. leach purification and the enrichment of solution, often adopt ion-exchange and solvent extraction technology or other chemical precipitation methods; 4. extract metal or compound from scavenging solution.Wherein in hydrometallurgy, main control step is for turning the stage of soaking, and the height that turns the rate of soaking directly determines feasibility and the economy of technique, affects extremely great and stir with the effect of mixing on leaching yield.
Stir and have a wide range of applications with being blended in hydrometallurgy industry, its operation object can be divided into following four aspects substantially: 1. prepare uniform mixture: as mediation, emulsification, solid suspension, kneading and granule mix etc.2. promote mass transfer: as extraction, leaching, dissolving, crystallization, gas absorption etc.3. promote to conduct heat: heating or cooling in steel basin.4. the combination, particularly some rapid reactions between above-mentioned three kinds of objects has higher requirement to mixing, mass transfer, stirs the controlling factor that often becomes process with the quality of mixing.
Although stir with to be blended in hydrometallurgy process be a kind of very conventional unit operation, due to its steady complicacy that flowed, the research of theoretical side is also not enough, the design to whipping appts and operation are so far still with very large empirical.Cause in hydrometallurgy experimental study and commercial process, because reaction medium viscosity is large, metalliferous mineral density is large, causes that solid is as easy as rolling off a log to be sunk to the bottom, and gas-liquid-solid three-phase contact is insufficient, and metalliferous mineral transformation efficiency reduces.Mix mass transfer so strengthen gas-liquid-solid three-phase, solid particulate fully disperses, and is to realize the high prerequisite that turns the rate of soaking.
Stir with mixing device and be mainly made up of agitator, agitator is divided into axial flow agitator, radial flow agitator and mixed flow agitator by flow-pattern.Paddle agitator is mainly used in the circulation of fluid, can not be used for Gas-Liquid Dispersion operation; Propeller agitator is axial flow agitator, and it is simple in structure, easily manufactured, and internal circulating load is large, and power of agitator is little, is usually used in the stirring of low viscosity fluid; Turbine type agitator is suitable for that material viscosity scope is wide, and shearing force is larger, dispersing fluid effective, and straight leaf and curved leaf turbine agitator mainly produce radial flow, and hinged joint turbine agitator mainly produces axial flow; Anchor formula and grid agitator are simple in structure, easily manufactured, are applicable to the material that viscosity is large, treatment capacity is large, and the large surface coefficient of heat transfer that is easy to get can reduce the generation of " wall built-up ".
