Utilizing The Weathering-typesepiolite To Prepare Metal Gangue Liquor Treating Compound

The text carried out the experimentation and research for the sepiolite deal with the mine waste water. That based on the investigate and analytical about the course , mechanism of the environmental pollution produced by the solid offal of mine. Especially for the fluid flow mineral dissolving and crystallization, metal mineral weathering and oxidization, heavy metal removal in the metal mine gangue storehouse.The weathering-typesepiolite is a kind of natural mineral which has very strong absorbs ability , the special structure conduced that it has good absorbs nature , rheological property, catalyzing. For solve gangue liquid pollution to environment from source, I utilize the weathering-typesepiolite, produced in LuoNan county, purified , soaked , activated by acid , to preparation a new clarificant to treatment gangue liquid. The text carried out the apart absorbing experiment about separately experiment and mix experiment of absorbing of solution to Pb²⁺,Cu²⁺, Zn²⁺ three heavy metal liquid. The result indicates , mix in three kinds of heavy metal in liquid, three kinds of ion have certain interference, different with the result while absorbing alone. Especially the behavior of Pb²⁺ is relatively obvious, so has carried on Cu²⁺ , Zn²⁺ two mixed kinds of experiment of absorbing of the solution, then the result is different for two ion absorb and Pb²⁺ absorbing.1.5mol/L sepiolite modified by hydrochloric acid has the best removal of rate to different density Pb²⁺, Cu²⁺, Zn²⁺. In the separately absorbing experiment of three kinds of ion heavy metal liquor: 99.9% best removal rates of Cu²⁺, 99.38% best removal rates of Zn²⁺, 97.05% best removal rates of Pb²⁺, the result of absorbing of Cu²⁺ is the best, and then the Zn²⁺ is better than Pb²⁺. And this conclusion has just proved: Ion radius more littler, absorbing result more better(Ion radius Cu²⁺ < Zn²⁺ < Pb²⁺); Mix liquid of three kinds of heavy metal: 99.38% best removal rates of Cu²⁺, 99.6% best removal rates of Zn²⁺, 99.94% best removal rate of Pb²⁺, violated the conclusion that Ion radius more littler, absorbing result more better; In...
